In this volume of the Barley Genetics Newsletter, sixty-four new and revised Barley Genetic Stock (BGS) descriptions are published (Table 1). The current lists of new and revised BGS descriptions, including those in Table 1, are again presented by BGS number order (Table 2) and by locus symbol in alphabetic order (Table 3) in this issue. Information on the description location, recommended locus name, chromosomal location, previous gene symbols, and the primary genetic stock (GSHO number and/or NGB number) are included in these lists. The GSHO stocks are held in the USDA-ARS Barley Genetic Stocks collection at the National Small Grains Collection (U.S. Department of Agriculture – Agricultural Research Service, National Small Grains Germplasm Research Facility, 1691 S 2700 W) Aberdeen, ID 83210, USA. The NGB stocks are held in the Nordic Genetic Resource Center (Nordgen), P.O. Box 41, SE-230 53 Alnap, Sweden. This information is available through the Internet at the following addresses:

* Recommended locus symbols are based on utilization of a three letter code for barley genes as approved at the business meeting of the Seventh International Barley Genetics Symposium at Saskatoon, Saskatchewan, Canada, on 05 August 1996.

 

Chromosome numbers and arm designations are based on a resolution passed at the business meeting of the Seventh International Barley Genetics Symposium at Saskatoon, Saskatchewan, Canada, on 05 August 1996. The Burnham and Hagberg (1956) designations of barley chromosomes were 1 2 3 4 5 6 and 7 while new designations based on the Triticeae system are 7H 2H 3H 4H 1H 6H and 5H, respectively.

 

The seed stock associated with each BGS number is held as a GSHO stock number in the Barley Genetics Stock Collection at the USDA-ARS National Grains Germplasm Research Facility, Aberdeen, Idaho, USA.

 


 

BGS 52, Chlorina seedling 15, fch15

 

Stock number:             BGS 52

Locus name:               Chlorina seedling 15

Locus symbol:             fch15

 

Previous nomenclature and gene symbolization:

Orange seedling = or (3).

Inheritance:

Monofactorial recessive (3).

Located in chromosome 2HS (3), about 18.5 cM distal from the fch1 (chlorina seedling 1) locus (2, 3); associated with SNP markers 2_1338 to 2_0699 (positions 74.97 to 126.33 cM) in 2H of the Bowman backcross-derived line BW357 (1), likely in 2H bin 06.

Description:

The normal color of seedlings is altered to "apricot yellow" when plants are grown in the field under low temperature. Plants respond better to higher temperatures and can be grown to maturity in suitable environments (3, 4). The yellow plant color is stable nearly to maturity (4).

Origin of mutant:

A spontaneous mutant in Trebi (PI 537442) (3).

Mutational events:

fch15.x (or1.a) in Trebi (Trebi IV, GSHO 49) (3).

Mutant used for description and seed stocks:

fch15.x in Trebi (GSHO 49), fch15.x in Bowman (PI 483237)*2 (BW357, NGB 20596).

BGS 55, Chlorina seedling 1, fch1

 

Stock number:             BGS 55

Locus name:               Chlorina seedling 1

Locus symbol:             fch1

 

Previous nomenclature and gene symbolization:

Chlorina seedling = f (6).

Light green = lg (5).

Light green 8 = lg8 (4).

Light green 10 = lg10 (4).

Inheritance:

Monofactorial recessive (3, 5, 6).

Located in chromosome 2HS (3, 10), in the centromeric region and about 4.0 cM distal from the eog1 (elongated outer glume 1) locus (3, 7), associated with SNP markers 1_1493 to 2_0458 (positions 76.05 to 96.47 cM) in 2HS of the Bowman backcross-derived line BW351 (1), likely in 2H bin 07.

Description:

Seedling and immature leaves are very pale yellow-green (chlorophyll deficient) (6). The leaves gradually change to a green color beginning with the leaf tip. Plants can be grown to maturity in the field, but they have a slightly yellow-green color and are stunted easily by stress. Plants of the Bowman backcross-derived line BW351 headed about 10 days later than Bowman and were slightly shorter. Plants produced a few more kernels per spike and rachis internodes were slightly shorter. Kernels were 10 to 15% lighter and they were slightly shorter and thinner. Grain yields were 1/2 to 2/3 of normal (2).

Origin of mutant:

A spontaneous mutant in Golden (Gull, CIho 1145, GSHO 466) (6).

Mutational events:

fch1.a (GSHO 112) in Gull (6, 9); fch1.p (lg) (Minn 80, GSHO 548) (5, 9); fch1.q (lg8) (No 155, GSHO 8) (4, 8); and fch1.r (lg10) (No 157, GSHO 154) in Himalaya (CIho 1312) (4).

Mutant used for description and seed stocks:

fch1.p in Minn 84-7 (GSHO 548); fch1.p in Bowman (PI 483237)*9 (GSHO 1886, BW351, NGB 20690).

BGS 62, Subjacent hood 1, sbk1

 

Stock number:             BGS 62

Locus name:               Subjacent hood 1

Locus symbol:             sbk

 

Previous nomenclature and gene symbolization:

Subjacent hood = sk (9).

Hooded awn 2 = k2 (12).

Hoods = kr (11).

Calcaroides-a = cal-a (4, 5).

Inheritance:

Monofactorial recessive (8, 9).

Located in chromosome 2HS (8, 9, 10), distal from molecular marker CDO057 (7), associated with SNP markers 1_0326 and 1_1059 (positions 16.91 and 17.96 cM) in 2HS of the Bowman backcross-derived line BW767, markers 1_1059 to 2_0563 (positions 17.96 to 21.19 cM) in 2HS of the Bowman backcross-derived line BW766, and marker 1_0326 (2), in 2H bin 02.

Description:

Unlike the Kap1 (hooded awn 1) mutants, the lemma appendage or its modification is situated somewhat below the top of the lemma. Lemma modifications may include a central cup-like cavity or sac in some alleles and/or pronounced lemma wings in other alleles (1, 7). The modified lemma bears a short distal awn. Only a few florets of the spike have malformations in alleles cal-a.3, -a.6, -a.7, and -a.17 and these alleles are associated with the formation of pronounced wings (7). There are no rudiments of a floral organ within the hood-like cavity (7, 8, 9). Leaf knots and leaf curling are present in some alleles (7). In the homozygous condition, the sbk1.a gene is epistatic to Kap1.a and to Lks1.a (awnless) genes (8). Plants of the Bowman backcross-derived lines BW103, BW766, and BW767 were much less vigorous than Bowman, about 3/4 of normal height and 3 to 4 fewer fertile rachis nodes. The kernel of the BW766 and BW767 plants were about 1/2 of normal weight, and grain yields were about 1/10 of normal. Plants of the BW103 line were more vigorous with kernel weights about 3/4 of those for Bowman and grain yield of about 1/2 of normal. The effects of the sbk1 mutants on plant vigor were less pronounced in cooler environments (3).

Origin of mutant:

A spontaneous mutant identified as Tayeh 13 (OUC335) (6); an X-ray induced mutant in Bonus (PI 189763) (6).

Mutational events:

sbk1.a (GSHO 267) in Tayeh 13 (8); cal-a.1 in Bonus (NGB 114280, 114281) (5, 6); cal-a.3 (NGB 114283), -a.5 (NGB 114285) in Foma (CIho 11333); cal-a.6 (NGB 114286) in Bonus; cal-a.7 (NGB 114287), -a.8 (NGB 114288, 114289), -a.11 (NGB 114290, 114291), -a.12 (NGB 114292), -a.13 (NGB 114293) in Foma; cal-a.16 (NGB 114295), -a.17 (NGB 114296), -a.20 (NGB 114299), -a.21 (NGB 114300) in Bonus (5, 6); sbk1.b (kr) in Montcalm (CIho 7149) (11).

Mutant used for description and seed stocks:

sbk1.a in Tayeh 13 (GSHO 267); sbk1.a via R.I. Wolfe’s multiple recessive stock for chromosome 2 in Bowman (PI 483237)*4 (BW766, NGB 22234); sbk1.b in Montcalm, in Bowman*7 (GSHO 1874, BW767, NGB 22235); cal-a.1 in Bonus (GSHO 286, NGB 114280, NGB 114281); cal-a.1 in Bowman*3 (GSHO 2186), in Bowman*6 (BW103, NGB 20509).

Located in chromosome 2HS (3, 4); associated with SNP markers 1_0525 to 1_0325 (positions 65.03 to 90.54 cM) in 2HS of the Bowman backcross-derived line BW192 and associated with markers 1_0943 to 1_1015 (positions 34.31 to 91.62 cM) in 2HS of the Bowman backcross-derived line BW187 (1); no SNP markers in 2HS were retained in Bowman backcross-derived line BW191 (1).

Description:

The spike is malformed because branch spikes fail to abort and rachis branches form from rachis nodes in the basal half of the spike. Spike branches form at more rachis nodes under favorable conditions for vigor growth (2, 5). Plants of the Bowman backcross-derived lines BW191 and BW192 were slightly shorter than Bowman and often had slightly shorter awns. Kernel sizes were variable for BW191 and BW192 and averages weights were lower than those of Bowman. Kernels were on average shorter and thinner, but BW191 plants had smaller grains than those of BW192. Grain yields of BW191 and BW192 were commonly lower than those of Bowman (2).

Origin of mutant:

An X-ray induced mutant in Donaria (PI 161974) (6).

Mutational events:

com2.f (Mut 2201, GSHO 1700) in Donaria (6); com2.g (GSHO 1703) from the ICARDA-CIMMYT collection of barley freaks (4); com2.k (GSHO 79) in Davis 1153 (), which likely is the same mutant as com2.g based on SNP markers retained in their Bowman backcross-derived lines (1).

Mutant used for description and seed stocks:

com2.f (GSHO 1700) in Donaria; com2.f in Bowman (PI 483237)*7 (GSHO 2233, BW191, NGB 22023); com2.g in a freak stock from CIMMYT (GSHO 1703); com2.g in Bowman (PI 483237)*8 (GSHO 1878, BW192, NGB 22024); com2.k (GSHO 79) in Davis 1153; com2.k in Bowman*3 (BW187, NGB 22019)

BGS 81, Glossy sheath 7, gsh7

 

Stock number:             BGS 81

Locus name:               Glossy sheath 7

Locus symbol:             gsh7

 

Previous nomenclature and gene symbolization:

Glossy sheath 7 = gs7 (3).

Inheritance:

Monofactorial recessive (3).

Located in chromosomes 1H, 2HL or 5H (1), based on segments of the donor parent chromosomes retained in the Bowman backcross-derived line BW410, possible locations based on SNP markers included 1_0259 to 2_0229 (positions 70.78 to 106.61 cM) in 1H, 1_0916 to 2_0681 (positions 187.68 to 247.86 cM) in 2HL, 1_0580 to 1_0955 (positions 54.27 to 69.76 cM) in 5HS, and 2_0367 to 2_1445 (positions 116.66 to 134.85 cM) in 5HL (1).

Description:

The spike, leaf sheath and stem of mutant plants are glossy and bright green in color (wax code - - ++) (3). In early generation backcrosses to Bowman, the glossy sheath 7 segregates headed early and had poor vigor and small spikes. Also, spikes frequently abort after emasculation (2). Plants of the Bowman backcross-derived line were 2/3 to 3/4 of normal height. Kernels are slightly longer and thinner than those of Bowman and kernel weights are about 2/3 of normal. Grain yields are less than 10% of normal (2).

Origin of mutant:

An ethyl methanesulfonate induced mutant in Akashinriki (OUJ659, PI 467400) (3).

Mutational events:

gsh7.ae (GSHO 1759) in Akashinriki (OUM022) (3).

Mutant used for description and seed stocks:

gsh7.ae in Akashinriki (GSHO 1759); gsh7.ae in Bowman (PI 483237)*5 (GSHO 2269, BW410, NGB 20643).

BGS 97, Accordion rachis 1, acr1

 

Stock number:             BGS 97

Locus name:               Accordion rachis 1

Locus symbol:             acr1

 

Previous nomenclature and gene symbolization:

Lax rachis internode = ril (2).

Accordion rachis = acr (5, 6).

Inheritance:

Monofactorial recessive (2, 5, 6), part of a multiple genic series involving acr1, acr2 and acr3 required for expression (3).

Located in chromosome 2HL (3), near the vrs1 (six-rowed spike 1) locus because no recombination with the Vrs1.t (deficiens) allele was observed (3); associated with SNP markers 1_0525 to 2_0667 (positions 65.03 to 117.73 cM) in 2H of the Bowman backcross-derived lines BW009 and BW439 (1), likely in 2H bins 06 to 08.

Description:

Rachis internodes are greatly elongated and often bent or pleaded as the spike emerges from the boot or sheath of the flag leaf (5). The line ACBV89B229, developed by R.I. Wolfe to maximize rachis internode length, exhibits extreme elongation of rachis internodes, rachis internode length values up to 7.0 mm, and occasionally trapping of the spike tip in the boot (3, 7). Elongation of the rachis internodes is associated with slightly elongated outer glumes and the deficiens (Vrs1.t) spike phenotype. Two modifiers, acr2 (see BGS 189) and acr3 (see BGS 241), apparently cause variable expression of the accordion trait in different genetic backgrounds. In crosses to Bowman, segregation for acr1 fit a three gene model based on DNA segments retained in the Bowman backcross-derived lines BW009 and BW439 (1, 3). Although the acr1 gene is apparently associated with the deficiens spike type, the large centromeric segment of 2H retained does not overlap the six-rowed spike 1 (vrs1) locus (1). A pericentric inversion can not be eliminated as a possibility. Plants in the BW009 and BW439 lines were about 3/4 of normal height and peduncles were about 1/2 of normal length. The number of fertile rachis nodes was reduced by about 3 and heading was delayed by up to 4 days. Kernels appeared thinner and weighted about 10% less. Test weights were low and grain yield was about 3/4 of normal (3).

Origin of mutant:

A naturally occurring deviant (4) incorporated into several genetic stocks, acr1.a in Beaverlodge stock ACBV89B229 was used to study this locus (3, 7).

Mutational events:

acr1.a in ACBV89B229 (GSHO 1617) and ACBV89232 (GSHO 1573) (7).

Mutant used for description and seed stocks:

acr1.a in ACBV89B229 (GSHO 1617); acr1.a in Bowman (PI 483237)*4 (GSHO 1899), in Bowman*7 (BW009, NGB 20417 and BW439, NGB 20671).

BGS 146, Calcaroides-d, cal-d

 

Stock number:             BGS 146

Locus name:               Calcaroides-d

Locus symbol:             cal-d

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (5, 6).

Located in chromosome 3H (7), near the centromere and near molecular marker CDO684 (7); associated with SNP markers 1_0672 to 2_1502 (positions 58.56 to 100.48 cM) in 3H of the Bowman backcrossed-derived line BW106 (2), in 3H bin 06.

Description:

At the tip of the lemma proper, in a position corresponding to the transition between lemma and awn, cal-d mutants bear a well-organized ectopic structure, the sac (1, 7). Only the allele cal-d.22 does not produce pronounced lemma wings. The cal-d mutants bear a short distal awn (7). In contrast to the Kap1 (hooded lemma 1) phenotype, the sac does not develop into an epiphyllous flower. The cal-d alleles are associated with leaf curling also (7). The awn malformation of cal-d mutants is associated with developmental activation of the phytomeric triad separating the lemma from awn (4). Plants of the Bowman backcross-derived line for cal-d.4, BW106, were about 3/4 of normal height and headed one day later than Bowman. Awns were 1/2 and peduncles were 2/3 of normal length and leaf blades were slightly narrower. Kernels of BW106 were thin and weighted about 1/3 less than those of Bowman. Test weights were low and grain yields were less than 1/2 of normal (3).

Origin of mutant:

An X-ray induced mutant in Foma (CIho 11333) (6, 7).

Mutational events:

cal-d.4 (GSHO 1698, NGB 114284) in Foma (6); cal-d.14 (NGB 119381) in Kristina (NGB 1500), -d.18 (NGB 114297), -d.22 (NGB 114301, 114302) in Bonus (PI 189763) (5).

Mutant used for description and seed stocks:

cal-d.4 in Foma (NGB 114284, GSHO 1698); cal-d.4 in Bowman (PI 483237)*6 (GSHO 1875), in Bowman*7 (BW106, NGB 20512).

BGS 150, Scirpoides leaf-b, scl-b

 

Stock number:             BGS 150

Locus name:               Scirpoides leaf-b

Locus symbol:             scl-b

 

Previous nomenclature and gene symbolization:

Scirpoides leaf-5 = scl.5 (3).

Inheritance:

Monofactorial recessive (2).

Probably located on chromosomes 3HL or 6HS (1), associated with SNP markers 2_0130 to 1_1172 (positions 151.97 to 190.87 cM) in 3HL and with SNP markers 1_0061 to 1_1205 (positions 70.15 to 82.43 cM) in 6HS of the Bowman backcross-derived line BW777 (1).

Description:

Leaf blades of scl-b plants are folded inward and are narrow compared to those of normal sibs. Folding of the leaf blade persists until maturity (2, 3). Plants of Bowman backcross-derived line BW777 were 15% shorter than Bowman, kernels were narrower and 15% lighter, and grain yields were about 25% lower (2). Plants of BW777 have inward folded leaf blades that are less than 2/3 as wide as those of Bowman (2). When grown in the greenhouse scl-b.5 plants had very narrow leaf blades that showed more inward folding than scl-a mutants. Also, the awns of spikes were often trapped by the collar of the flag leaf during spike emergence (2). A new locus symbol is recommended based on the morphological differences compared to scl-a mutants and the lack of SNP markers retained in chromosome 1HL (1, 2).

Origin of mutant:

A mutant was induced by UV-ray treatment of pollen grains of Bonus (PI 189763) (3).

Mutational events:

scl-b.5 in Bonus (NGB 117103) (3).

Mutant used for description and seed stocks:

scl-b.5 in Bonus (NGB 117103), scl-b.5 in Bowman (PI 483237)*3 (BW777, NGB 20754).

Stock number:             BGS 155

Locus name:               Glossy leaf 1

Locus symbol:             glf1

 

Previous nomenclature and gene symbolization:

Waxless bloom on leaves = w1 (13).

Glossy = gl (11).

Glossy leaves = gl (18).

Glossy leaf = gl (17).

Glossy seedling 2 = gl2 (5, 11).

Eceriferum-zh = cer-zh (6).

Inheritance:

Monofactorial recessive (11).

Located in chromosome 4HL (5, 11, 14, 16); about 7.5 cM distal from the lbi2 (long basal rachis internode 2) locus and about 4.8 cM distal from the Mlg (Reg2, reaction to Erysiphe graminis 2) locus (2); associated with SNP markers 2_0820 to 1_0606 (positions 89.78 to 95.92 cM) in 4HL of the Bowman backcross-derived line BW385 (1), in 4H bin 06.

Description:

Surface wax coating on the leaf blade appears absent from the seedling stage to near maturity, and leaves have a shiny appearance (wax code ++ ++ -) (6). Plants are semidwarf, relatively weak, and late in heading. The stock in the Bonus is highly sterile (6), but the Bowman backcross-derived line has nearly complete fertility. The lack of surface waxes reduces the ability of growing germ tube of certain fungi to find the stomata openings (12). Plants of Bowman backcross-derived line BW385 were 5 to 15% shorter than Bowman and headed about 2 days later. Kernel weights were about 20% lower and grain yields were approximately 3/4 of normal (3).

Stock number:             BGS 186

Locus name:               Slender dwarf 3

Locus symbol:             sld3

 

Previous nomenclature and gene symbolization:

Anthocyanin-free = ant-567 (6).

Proanthocyanidin-free 17.567 = ant17.567 (5).

Slender dwarf e = sld.e (4).

Inheritance:

Monofactorial recessive (2).

Located in chromosome 4HS (3), based on linkage drag with the int-c (intermedium spike-c) locus (3); associated SNP markers 1_0208 to 2_0777 (positions 5.24 to 40.15 cM) in 4HS of the Bowman backcross-derived line BW863 (1).

Description:

The mutant gene sld3.e was isolated as a second mutant in the stock ant17.567 (proanthocyanidin-free 17) (2). Plants show reduced vigor and are about 3/4 normal height. The number of spikelets per spike is about 3/4 that of normal sibs and kernels are slightly smaller. Rachis internodes can be slightly longer and grain yields are about 3/4 of normal. The Bowman backcross-derived line BW863 for sld3.e did not show a reduction in anthocyanin pigmentation or a large reduction in kernel size (2). Plants of BW863 were about 10% shorter than Bowman and peduncles were about 20% shorter. Rachis nodes were slightly longer and kernels per spike can be reduced up to 20% in some environments. Kernels were slightly shorter and thinner than those of Bowman and seed weights were 10 to 15% less. Grain yields were slightly reduced compared to those of Bowman (2).

BGS 189, Accordion rachis 2, Acr2

 

Stock number:             BGS 189

Locus name:               Accordion rachis 2

Locus symbol:             Acr2

 

Previous nomenclature and gene symbolization:

Lax spike = lax (4, 9, 11).

Accordion rachis = acr (7, 9, 12).

Accordion rachis 1 = acr1.a (6).

Accordion rachis b and c = acr.b, acr.c (3, 5).

Laxatum spike stocks = Lax.aa, Lax.ab, Lax.am, lax.ao, (5, 12).

Inheritance:

Monofactorial incomplete dominant for lax spike, one of three factors required for expression of accordion rachis trait (5, 12).

Located in chromosome 4HL; associated with SNP markers 1_0123 to 2_1018 (positions 158.82 to 183.54 cM) in 4HL of the Bowman backcross-derived lines BW445; Bowman backcross-derived lines BW007, BW008, BW009, BW439, BW444, and BW456 have identical heterogeneous SNP markers in 4HL, but their segments from the donor parent are longer than those of BW445 (3), in 4H bin 11 or 12.

Description:

Rachis internodes are elongated and kernels appear longer than normal. The Acr2 gene is in the second of three chromosomal regions associated with expression of the accordion rachis trait in Bowman backcross-derived lines BW009 and BW439. The long rachis internode trait was specifically added to the original accordion rachis stock by R.I. Wolfe (12). Characteristics associated with variants at the Acr2 locus are difficult to determine because only the Bowman backcross-derived line BW444 (Lax.aa or Acr2.aa) did not have more than one chromosome segment from its donor parent (3). Rachis internodes of BW444 plants were about 30% longer, 4.6 vs. 3.5 mm, than those of Bowman. Leaf blades were slightly longer and wider. Kernels were slightly longer and heavier, 61 vs. 58 mg. Grain yields were equal or slightly more than those of Bowman. The donor parent (FN280) of the BW444 line traces to the lines developed by M.L. Martini and H.V. Harlan (8) in Idaho via crosses to six-rowed barley made by D.C. Rasmusson (10). The Bowman backcross-derived lines BW007 (Acr2.b2) and BW008 (Acr2.c2) had the identical segment of chromosome 4HL plus a 1H segment retained from their donor parents; however, the 1H segments in these lines differed for SNP marker patterns (3). The Bowman lines BW007 and BW008 were 10 to 15% taller than Bowman. The rachis internodes of BW007 were about 25% longer than those of Bowman, 4.7 vs. 3.7 mm., Burma Girl (GSHO 1071, Acr2.b2), the original stock for BW007, has several sterile rachis nodes at the base of the spike before spikelet development is initiated (4). BW007 had kernel weights that varied across experiments from smaller to slightly larger than those of Bowman. The rachis internodes of BW008 were nearly twice as long as those of Bowman, 6.8 vs. 3.7 mm, but they did not show the accordion-like bending associated with the accordion phenotype. Kernels of the BW008 line were slightly longer and heavier than those of Bowman (5). Two other Bowman backcross-derived lines, BW439 and BW456, have the 4HL SNP pattern associated with the Acr2 locus. Both originate from the same donor stock AB1398 (GSHO 1115) from Aberdeen, Idaho and are assigned the gene symbol Acr2.am. BW456 was selected based on lax spikes while BW439 was selected based on tall plants (5).

Origin of mutant:

A naturally occurring deviant possibly in Long Rachis Internode (CIho 6164), developed by M.L. Martini and H.V. Harlan (8), or Burma Girl (CIho 14831), donated to the USDA Small Grains Collection by G.A. Wiebe. The Acr2 gene has been incorporated into several genetic stocks from that source.

Mutational events:

Acr2.b2 in Burma Girl (CIho 14831, GSHO 1071) (5, 12); Acr2.aa in FN280 (GSHO 1572) (5, 10); Acr2.a2 in ACBV89B229 (GSHO 1617) and Acr2.ab from ACBV89B232 (GSHO 1573) (12); Acr2.c2 in T188 (GSHO 1480) from R.W. Woodward (2); Acr2.am in AB 1398 [GSHO 1115, likely CIho 14785 from G.A. Wiebe (1)]; all alleles may have been derived from one stock (3, 5).

Mutant used for description and seed stocks:

Acr2.aa in FN280 (GSHO 1572), Acr2.b2 in Burma Girl (GSHO 1071), Acr2.a2 in ACBV89B229 (GSHO 1617); Acr2.c2 in T188 (GSHO 1480); Acr2.am in AB 1398 (GSHO 1115); Acr2.a2 from ACBV89229 in Bowman*4 (GSHO 1899), in Bowman*7 (BW009, NGB 20417 and BW439, NGB 20671); Acr2.aa from FN280 in Bowman*4 (GSHO 2276), in Bowman*5 (BW444, NGB 20676); Acr2.ab from ACBV89B232 (GSHO 1573) in Bowman*4 (GSHO 2277), in Bowman*6 (BW445, NGB 20677); Acr2.b2 from Burma Girl in Bowman *2 (GSHO 1898), in Bowman*5 (BW007, NGB 20415); Acr2.c2 from T188 in Bowman*6 (BW008, NGB 20416); Acr2.am from AB 1398 in Bowman*4 (BW456, NGB 20688).

BGS 190, Thick filament 1, tfm1

 

Stock number:             BGS 190

Locus name:               Thick filament 1 (male sterile genetic)

Locus symbol:             tfm1

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (2).

Located in chromosome 1HL (1); associated with SNP markers 2_0603 to 2_0915 (positions 199.04 to 202.94 cM) in 1HL of a heterozygous plant from the Bowman backcrossed-derived line BW877 (1), in 1H bin 14.

Description:

The filaments supporting the anthers are much thicker (sheath-like) than normal, having a stalk-like appearance and a light green color. Since the filaments do not elongate, the mutant plants are largely male-sterile. Pollen fertility is apparently normal because mutant segregates will set a few seeds. Besides very poor seed, tfm1 plants in Bowman backcross-derived line BW877 appeared normal (2).

Origin of mutant:

A spontaneous mutant in the Volla (PI 280423) induced mutant 7060 backcrossed twice to Bowman (PI 483237) (2).

Mutational events:

tfm1.a in 7060/2*Bowman from Volla (2).

Mutant used for description and seed stocks:

tfm1.a from Volla (7060/2*Bowman), in Bowman (PI 483237)*7 (BW877, NGB 22311).

BGS 191, Chlorina seedling 17, fch17

 

Stock number:             BGS 191

Locus name:               Chlorina seedling 17

Locus symbol:             fch17

 

Previous nomenclature and gene symbolization:

Very yellow 3 = vy3 (3).

Chlorina seedling vy = fch.vy (3).

Inheritance:

Monofactorial recessive (2).

Located in chromosomes 1HL or 3HL (1), associated with SNP markers 1_0830 to 2_0940 (positions 130.68 to about 179 cM) in 1HL and SNP markers 2_0130 to 1_0343 (positions 151.97 to 255.13 cM) in 3HL of the Bowman backcrossed-derived line BW344 (1).

Description:

Seedlings are pale yellow with a slight mottled type streaking and vigor is poor. The second leaf blade is chlorotic with the tip gradually turning green. Mature plants are normal green and have apparently normal vigor (3). In the Bowman backcross-derived line BW344, heading date was delayed by about 9 days compared to Bowman and grain yields were 50 to 70% of normal. Other morphological traits of BW344 plants were similar to those of Bowman (2). A new gene symbol is assigned to the vy3 mutant because no other chlorina mutant with a similar phenotype, except fch7, is associated with either 1HL or 3HL (1, 2).

Origin of mutant:

A spontaneous mutant in Himalaya X Ingrescens (GSHO 681) (3).

Mutational events:

fch17.vy (E 37-517, NSL 30243, GSHO 1079) in Himalaya X Ingrescens (2, 3).

Mutant used for description and seed stocks:

fch17.vy from Himalaya X Ingrescens (GSHO 1079) in Bowman (PI 483237)*5 (BW344, NGB 22139).

BGS 203, Black lemma and pericarp 1, Blp1

 

Stock number:             BGS 203

Locus name:               Black lemma and pericarp 1

Locus symbol:             Blp1

 

Previous nomenclature and gene symbolization:

Black lemma and caryopsis = B (8).

Black pericarp = Bk (1).

Black lemma and pericarp = B (9).

Inheritance:

Monofactorial dominant (1, 6, 8).

Located in chromosome 1HL (5, 7), about 16.0 cM proximal from the trd1 (third outer glume 1) locus (5); about 8.8 cM proximal from RFLP marker ABC261 in 1H bin 13 (2); associated with SNP markers 2_0959 to 2_0603 (positions 173.49 to 199.04 cM) in 1HL of the Bowman backcross-derived line BW062 and SNP marker 2_0940 (about position 179 cM) in 1HL of the Bowman backcross-derived line BW060 (3), in 1H bin 13.

Description:

Black pigmentation of the lemma and pericarp develops slightly before maturation of the spike. Pigmented organs may include all parts of the spike, awns, the upper portion of the stem, and upper leaves. The intensity of pigmentation associated with each of the dominant alleles at the Blp1 locus is characteristic of that allele, and is relatively stable over environments (9). Black seed is produced by melanin-like pigment in the pericarp (1). Woodward (9) reports that the dominance ranking of alleles at the Blp1 locus is related to the intensity of black pigmentation they confer, with the Blp1.b (B) allele conferring extreme black pigmentation. The Blp1.mb (Bmb) allele is associated with medium black and a reduced distribution pattern; and the Blp1.g (Bg) allele is associated with light black or gray coloration (9, 10). In the Bowman backcross-derived lines for the Blp1 locus, BW060 and BW062, the expression of other morphological traits appeared similar to those of Bowman (4).

Origin of mutant:

Natural occurrence in several cultivars (8, 9).

Mutational events:

Blp1.b (B) in Hordeum distichon var nigrinudum No 1 (GSHO 988) (9); Blp1.mb (Bmb) in CIho 2970 (GSHO 226) (9); Blp1.g (Bg) in Blackhull (CIho 878, GSHO 199) and Black Smyrna (CIho 191, GSHO 222) (9).

Mutant used for description and seed stocks:

Blp1.b in Hordeum distichon var nigrinudum No 1 (GSHO 988); Blp1.b from R.I. Wolfe's Multiple Dominant Marker Stock (GSHO 1580) in Bowman (PI 483237)*8 (GSHO 2054, BW062, NGB 20470); likely Blp1.g from a Composite Cross in Bowman *5 (BW060, NGB 20468).

Stock number:              BGS 220

Locus name:                 Chlorina seedling 3

Locus symbol:               fch3

 

Previous nomenclature and gene symbolization:

Chlorina seedling 3 = f3 (3).

Inheritance:

Monofactorial recessive (3, 4).

Located in chromosome 1HS (4, 5, 6, 7), near the tip of 1HS associated with SNP markers 2_0479 to 3_0969 (at position 0.0 cM) in 1HS of the Bowman backcross-derived line BW359 (1), in 1H bin 01.

Description:

Seedlings have bright yellow leaves, which gradually change color to a light green as the plant grows. Plants are vigorous, but remain chlorina or light green until maturity. Plants expressing the fch3.d gene can be distinguished readily from normal plants at all stages of growth (3, 4). Heading of plants in the Bowman backcross-derived line BW359 was delayed by 5 to 8 days, plants were about 3/4 of normal height, seeds were 10 to 20% lighter, and seed yields were less than 1/2 of normal (2).

Origin of mutant:

A spontaneous mutant in an unknown six-rowed cultivar (3).

Mutational events:

fch3.d in an unknown cultivar (Minn 89-4, GSHO 851) (3).

Locus name:               Zebra stripe 3

Locus symbol:             Zeb3

 

Previous nomenclature and gene symbolization:

Zoned leaf c = zbc (2, 4, 5, 6, 9).

Zebra stripe c = zbc (6, 7).

Zoned leaf c2 = zbc2 (2, 4, 5).

Zebra stripe c2 = zbc2 (6).

Zebra stripe 3 = zb3 (7).

Inheritance:

Monofactorial incomplete dominant (2, 8, 9).

Located in chromosome 1HL (2, 4); associated with SNP markers 1_0275 to 2_0997 (positions 63.72 to 89.01 cM) in 1H of a heterozygous plant from the Bowman backcross-derived line BW932 (1), in 1H bin 08.

Description:

Early leaves of homozygous plants have bright yellow bands across a light yellow background when grown under alternating temperatures, warm day and cool night (2). Later leaves have patches of bright yellow. Cool temperatures enhance the yellow banding while warm temperatures increase green pigments. Under very cold conditions, leaves become yellowish white and deteriorate. Heterozygotes have slightly pale green color compared to normal plants (2). The Zeb3.c gene must be maintained as a heterozygous stock because seed production on mutant plants is rare.

Origin of mutant:

A spontaneous mutant from the collection of genetic stocks maintained by Woodward (2, 5).

Mutational events:

Zeb3.c (GSHO 1451) in an unknown cultivar (Utah 41, Alb Acc 43) (2, 3 ,5).

Located in chromosome 1HL (9, 10, 11, 12, 13); slightly distal from the cer-e (eceriferum-e) locus (6, 13, 14); about 19.3 cM proximal from the nec1 (necrotic leaf spot 1) locus (7); associated with SNP markers 1_0259 to 1_0520 (positions 70.78 to 82.35 cM) in 1HL of the Bowman backcross-derived line BW304 (1), likely in 1H bin 08.

Description:

Spikes have a compact appearance caused by a reduction in rachis internode length with rachis internode length values from 1.9 to 2.3 mm. Culms are shorter than those of parental cultivars (12). GA3 treatment of plants as the flag leaf emerges decreased spike density (15). Plants of the Bowman backcross-derived line had slightly shortened peduncles and were about 5/6 of normal height. Rachis internode lengths were 2.9 vs. 3.7 mm. Kernels were slightly shorter and wider and weights were often about 10% higher. Grain yields were about 3/4 of normal (2).

Origin of mutant:

An X-ray induced mutant in Gull (CIho 1145, GSHO 466) (3, 4, 5).

BGS 227, Small lateral spikelet 1, sls1

 

Stock number:             BGS 227

Locus name:               Small lateral spikelet 1

Locus symbol:             sls1

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (3).

Located in chromosome 1HL (3), closely linked to the msg1 (male sterile genetic 1) locus (3); associated with SNP markers 1_0933 to 3_0343 (positions 82.35 to 87.19 cM) in 1HL) of the Bowman backcross-derived line BW867 (1), in 1H bin 08.

Description:

Sterile lateral spikelets become progressively smaller toward the tip of two-rowed spikes in plants, which express the Vrs1.b and int-c.b alleles at the six-rowed spike 1 and intermedium spike-c loci, respectively. The terminal rachis nodes generally have rudimentary lateral spikelets. Expression of the sls1 is affected by genetic background, but express is often stronger in late tillers. The trait can be observed only in two-rowed segregates from crosses between six- and two-rowed cultivars. No significant differences in agronomic traits were observed between backcross-derived BW867 and Bowman, but kernels tended to be wider and heavier and test weights are slightly higher (2).

Origin of mutant:

Natural occurrence in six-rowed cultivars derived from Manchurian introductions, but it can not be observed visually in six-rowed barley cultivars.

Mutational events:

sls1.a in MSS005 [msg1.ca from CIho 5368 in Betzes (PI 129430)*11 (GSHO 1810)], sls1.a (GSHO 2492) in Morex (CIho 15773).

Mutant used for description and seed stocks:

sls1.a in Morex (CIho 15773, GSHO 2492); sls1.a from MSS005 in Bowman (PI 483237)*8 (GSHO 2034, BW867, NGB 22304).

BGS 228, Subcrown internode length 1, Sil1

 

Stock number:             BGS 228

Locus name:               Subcrown internode length 1

Locus symbol:             Sil1

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial incomplete dominant (1).

Located in chromosome 1H (4), based on linkage drag with the sls1 (small lateral spikelet 1) locus (4); associated with SNP markers 1_0259 to 1_0890 (positions 70.78 to 110.10 cM) in the 1H centromeric region of the Bowman backcross-derived line BW852 (2), in 1H bin 08 or 09.

Description:

Plants have relatively short subcrown internodes, 0.0 to 1.0 cm, when planted 9 cm deep in vermiculite. Planting depth and subcrown internode length determine the position of the crown in relation to the soil surface (1). Plants with a deeper crown placement show higher levels of winter survival (5). In generating the Bowman backcross-derived line, the Sil1 gene showed a dominant inheritance pattern. No other morphological effects for the Sil1.a gene were noted in Bowman backcross-derived line BW852 (3).

Origin of mutant:

Natural occurrence in NE 62203 (CIho 15542), a selection of unknown origin (1).

Mutational events:

Sil1.a (GSHO 1604) in winter barley NE 62203 (1).

Mutant used for description and seed stocks:

Sil1.a in NE 62203 (GSHO 1604); Sil1.a in Bowman (PI 483237)*5 (GSHO 2032), Sil1.a in Bowman*7 (BW852, NGB 22289).

BGS 232, High lysine 4, Lys4

 

Stock number:                    BGS 232

Locus name:                       High lysine 4

Locus symbol:                     Lys4

 

Previous nomenclature and gene symbolization:

Shrunken endosperm xenia 5 = sex5g (8).

Inheritance:

Monofactorial incomplete dominant (1, 5).

Located in chromosome 1HS (5, 6, 8), over 35.1 cM distal from the ert-b (erectoides-b) locus (6); associated with SNP markers 2_0373 to 1_0744 (positions 0.0 to 39.84 cM) in 1HS of the Bowman backcross-derived line BW497 (3), in 1H bins 01 to 03.

Description:

At the hard dough stage, kernels homozygous for the Lys4.d gene develop a depression near the center of the lemma, which becomes progressively more distinct as the kernels mature. Grain produced by mutant plants has a 9% increase in lysine content (1, 2). Shrunken endosperm has a pleiotropic association with the high lysine gene Lys4.d (5). Kernels heterozygous at the Lys4 locus may develop a slightly less distinct depression on the dorsal side (5). Maintenance of Lys4.d stocks may be difficult because outcrosses are not recognized easily. Plants of Bowman backcross-derived line BW497 were slightly shorter and kernel weights and grain yields were about 2/3 of normal (4).

Origin of mutant:

An ethyl methanesulfonate induced mutant in Bomi (PI 43371) (2).

Mutational events:

Lys4.d in Bomi (Risø 8, GSHO 2475) (1, 2, 7).

Mutant used for description and seed stocks:

Locus name:               Breviaristatum-t

Locus symbol:             ari-t

 

Previous nomenclature and gene symbolization:

Breviaristatum-25 = ari-25 (3).

Inheritance:

Monofactorial recessive (2, 4).

Located in chromosome 1H (1); associated with SNP markers between 1_0744 to 1_1326 (positions 39.84 to 82.35 cM) in 1H of the Bowman backcross-derived line BW032 (1), in 1H bins 05 to 08.

Description:

The awns of ari-t plants are 2/3 of normal length and slightly curly. Peduncles are coiled and less than half normal length and plants are 1/2 to 2/3 normal height (4, 5). In the Bowman backcross-derived line BW032, leaf blades were shorter and narrower than those of Bowman. Kernels were shorter and narrower, seed weights were about 20% lower, and seed yields were about 1/4 of normal (2). A locus name was assigned based on the unique phenotype and lack of other breviaristatum mutants located in 1H.

Accordion rachis c = acr.c (4).

Accordion rachis 1 = acr1.a (5).

Inheritance:

Monofactorial incomplete dominant for lax spike, the third factor required for expression of accordion rachis 1 (acr1) trait (3, 4).

Located in chromosome 1HL (3), associated with SNP markers 2_1357 to 2_0997 (positions 76.96 to 94.86 cM) in 1HL of the Bowman backcross-derived lines BW009 and BW439 (3), likely in 1H bin 08. Bowman lines BW007, BW009, BW438 and BW456 contain longer overlapping segments of variable length and SNP marker patterns in 1H (3).

Description:

Plants have slightly elongated rachis internodes (1). The Acr3 gene is in the third chromosomal region associated with expression of the accordion rachis trait in Bowman backcross derived lines BW009 and BW439. The contribution of the 1HL region to characteristics of the accordion phenotype is unknown. Only the line BW438 (Lax.an or Acr3.an) has a 1HL donor chromosome segment in a line lacking both the 2H and 4HL segments identified as containing the acr1 (see BGS 097) and Acr2 (see BGS 189) genes, respectively. Plants of the Bowman derived line BW438 were taller than Bowman and had slightly longer rachis internodes (4).

Origin of mutant:

A naturally occurring deviant for lax spike from several sources (3, 4).

Mutational events:

Acr3.a3 in ACBV89B229 (GSHO 1617) and ACBV89B232 (GSHO 1573) (3, 9); Acr3.b3 in Burma Girl (CIho 14831, GSHO 1071) (4, 9); Acr2.am2 and Acr3.an in AB 1398 [GSHO 1115, likely CIho 14785 from G.A. Wiebe (1)]; Acr3.c3 in T188 (GSHO 1480) from R.W. Woodward (2).

BGS 242, Slender dwarf 6, sld6

 

Stock number:             BGS 242

Locus name:               Slender dwarf 6

Locus symbol:             sld6

 

Previous nomenclature and gene symbolization:

Slender dwarf g = sld.g (3).

Inheritance:

Monofactorial recessive (2, 3).

Located in chromosome 1H (1), associated with SNP markers 1_0259 to 1_0552 (positions 70.78 to 88.33 cM) in 1H and SNP markers 2_0226 to 2_0206 (positions 3.14 to 9.61 cM) in 5HS of the Bowman backcross-derived line BW854 (1), likely in 1H bin 07 or 08.

Description:

Plant height of the sld6.g mutant is reduced and leaf blades are much shorter and slightly narrower (2). Plants of the Bowman backcross-derived line BW854 were 15 to 25% shorter than those of Bowman and spikes had about 4 fewer fertile rachis nodes. Spikes were semi-compact with rachis internodes about 25% shorter than those of Bowman. Kernels of BW854 were shorter and slightly thinner than those of Bowman. Kernel weights and grain yields were about 3/4 of normal (3). Based on the heterogeneous SNP marker positions in BW954, sld6.g is not an allele at any of the previously named slender dwarf loci (1, 3).

Origin of mutant:

A sodium azide induced mutant in Glenn (CIho 15769) (2).

Mutational events:

sld6.g (GSHO 2482) in Glenn (2, 3).

Mutant used for description and seed stocks:

sld6.g (GSHO 2482) in Glenn; sld6.g in Bowman (PI 483237)*5 (GSHO 2355), in Bowman*7 (BW854, NGB 22291).

BGS 308, Long basal rachis internode 1, lbi1

 

Stock number:             BGS 308

Locus name:               Long basal rachis internode 1

Locus symbol:             lbi1

 

Previous nomenclature and gene symbolization:

Curved peduncle = cr (1).

Long basal spike internode = bi (5).

Long basal spike internode = lb (7).

Rachisextensum = rac-a and rac-b (4, 8).

Inheritance:

Monofactorial recessive (1, 5).

Located in chromosome 5HL (5), about 16.0 cM distal from the raw1 (smooth awn 1) locus (5); located in chromosome 1H associated with SNP markers 1_0238 to 2_0550 (positions 55.85 to 130.68 cM) or in chromosome 5HS with SNP markers 2_0226 to 1_0553 (positions 3.14 to 26.06 cM) of the Bowman backcross-derived line BW471 (2).

Description:

The first or basal rachis internode is much longer than the other rachis internodes. Basal internode lengths range from less than 1 cm to more than 20 cm (5, 9). Genotype, environmental conditions, and tiller health alter basal rachis internode elongation in plants homozygous for the lbi1.a gene. Expression of the lbi1.a gene is commonly more pronounced in six-rowed genotypes than in two-rowed ones. In many environments, plants of the Bowman backcross-derived line BW471 were about 10% taller than Bowman and had longer peduncles. Rachis internodes were slightly longer and spike often had one or two more fertile rachis nodes. Kernels of BW471 plants were often slightly longer and heavier than those of Bowman (3). The marker data for BW471 conflict with the previously reported chromosomal location for lbi1.a, but the presence of the SNP marker pattern of the donor parent segments in BW471 suggests a six-rowed origin of the segments (2).

Origin of mutant:

Natural occurrence in Wisconsin Pedigree 38 (Barbless, CIho 5105, GSHO 580) (5), and in many other six-rowed cultivars of Manchurian origin (5, 8).

Mutational events:

lbi1.a (GHSO 580, CIho 5105) in Wisconsin Pedigree 38 (5); rac-a.2 (NGB 114845) and rac-b.1 (NGB 114844) in Bonus (PI 189763) are not alleles of each other (6); but both rac-a.2 and rac-b.1 are reported to be alleles at the lbi1 locus (8).

Mutant used for description and seed stocks:

lbi1.a in Wisconsin Pedigree 38 (GSHO 580); lbi1.a in Bowman (PI 483237)*5 (GSHO 2144), in Bowman*6 (BW471, NGB 20701).

BGS 315, Six-rowed spike 3, vrs3

 

Stock number:             BGS 315

Locus name:               Six-rowed spike 3

Locus symbol:             vrs3

 

Previous nomenclature and gene symbolization:

Six-rowed spike 3 = v3 (3).

Intermedium spike-a = int-a (6, 7, 9, 13).

Intermedium spike-g = int-g (6, 7, 11).

Inheritance:

Monofactorial recessive (3, 5, 7, 9, 11).

Located in chromosome 1HL (4, 8, 14), near the centromere and proximal from the ert-b (erectoides-b) locus (8, 14); int-a.1 is associated with SNP markers 2_0619 to 1_1361 (positions 50.96 to 82.35 cM) in 1H of the Bowman backcross-derived line BW419 (1), vrs3.f is associated with SNP markers 1_0575 to 1_0075 (positions 37.21 to 82.35 cM) in 1H of the Bowman backcross-derived line BW902 (1), in 1H bin 07 or 08.

Description:

The upper half of the spike appears six-rowed, but lateral spikelets in the lower half are reduced in size. The basal portion of the spike appears two-rowed. Awns on the lateral spikelets range from normal near the top, to awnletted or pointed in the middle, to awnless at the base of the spike. Seeds may develop in lateral spikelets of only the upper two-thirds of the spike. Lateral spikelets may be pedicellated in some stocks. Central spikelets often have double awns, one on the lemma and one on the palea. The rachilla may be deformed (3, 4, 5, 6, 11, 12). In Bowman backcross-derived lines BW419 and BW902, plants were often slightly shorter, rachis internodes were slightly longer, and kernels were thinner than those of Bowman. Kernel weights for BW419 ranged from 70 to 85% of normal compared to only 60 to 75% for those of BW902. Grain yields of Bowman lines BW419 and BW902 were often lower than those of Bowman (2).

Origin of mutant:

A gamma-ray induced mutant in Hakata 2 (OUJ807, PI 263407) (3, 5), an X-ray induced mutant in Bonus (PI 189763) (7).

BGS 356, Glossy sheath 6, gsh6

 

Stock number:             BGS 356

Locus name:               Glossy sheath 6

Locus symbol:             gsh6

 

Previous nomenclature and gene symbolization:

Glossy sheath 6 = gs6 (16).

Eceriferum-c = cer-c (5).

Eceriferum-cqu = cer-cqu (14, 22).

Inheritance:

Monofactorial recessive (5, 16, 18).

Located in chromosome 2HS (18, 19, 20), in a subterminal position (17); associated with SNP markers 1_0326 to 2_0563 (positions 16.91 to 21.19 cM) in 2HS of the Bowman backcross-derived line BW409 (1), in 2H bin 02.

Description:

A bright, glossy green color is apparent on the spike, leaf sheath, and stem (16). The gsh6 locus is the cer-c component of the complex locus cer-cqu (2), which controls formation of β-diketone lipids in epicuticular wax layer (21, 22). Most alleles have the wax code - - ++, but a few alleles show delayed development of surface waxes on the sheath (wax code - +/- ++) (5, 15). The only observed morphological difference between Bowman and the backcross-derived line BW409 was an increase in kernel length (3).

Origin of mutant:

An X-ray induced mutant in Bonus (PI 189763) (5), a radiation induced mutant in Domen (CIho 9562) (16).

BGS 400, Eceriferum-e, cer-e

 

Stock number:             BGS 400

Locus name:               Eceriferum-e

Locus symbol:             cer-e

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (5).

Located in chromosome 1HL (2, 14), close to the centromere and near the ert-b (erectoides-b) locus (4, 14, 15); associated with SNP markers 1_0764 to 1_1326 (positions 61.55 to 82.35 cM) having the Bonus haplotype in 1H of the Bowman backcross-derived line BW109 via Wolfe’s Recessive Marker Stock 5.2 (1), likely in 1H bin 08.

Description:

Surface wax coating on the spike appears absent or greatly reduced (wax code

-/+ ++ ++) (5). A translocation is present in the allele cer-e.18, but it is not linked to the cer-e locus (5). The Bowman backcross-derived line has less wax on the spike and upper leaf sheath (wax code - + ++). Plants of the Bowman backcross-derived line BW109 had slightly longer awns and rachis internodes than Bowman. Kernels weights were slightly lower, but grain yields were equivalent (3).

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (3).

Located in chromosome 1H (1), associated with SNP markers 1_0764 to 2_1126 (positions 61.51 to 110.10) in 1H of the Bowman backcrossed-derived line BW110 (1); previously located in chromosome 7H (8), near the centromere and about 4.5 cM proximal from the ert-d (erectoides-d) locus (8, 9, 10), and about 6.3 cM distal from the nud1 (naked caryopsis 1) locus (9, 10).

Description:

In the original stock surface wax coating on the spike, leaf sheath, and stem is reduced (wax code + + ++) (3). Reduced surface wax coating was apparent only on the spike (wax code + ++ ++) in the Bowman backcross-derived line, BW110. Plants BW110 were slightly taller than Bowman. Kernel weights varied from slightly lower to slightly more; grain yields were slightly less (2). Allelism tests need to be conducted to confirm that BW110 has the cer-f.9 mutant.

BGS 413, Glossy sheath 8, gsh8

 

Stock number:             BGS 413

Locus name:               Glossy sheath 8

Locus symbol:             gsh8

 

Previous nomenclature and gene symbolization:

Eceriferum-u = cer-u (6).

Glossy sheath 8 = gs8 (4).

Inheritance:

Monofactorial recessive (6).

Located in chromosome 2HS (17), based on close association with the gsh6 (glossy sheath 6) locus (2, 5, 17, 18), in a subterminal position (16); associated with SNP markers 2_1377 to 1_0919 (positions (20.11 to 66.78 cM) in 2HS of the Bowman backcross-derived line BW411 (1), in 2H bin 02 or 03.

Description:

The wax coating on the spike, stem and leaf sheath appears reduced (wax code + + ++) (6). The gsh8 locus is the cer-u component of the complex locus cer-cqu which controls epicuticular wax layer formation on the surface of the spike, leaf sheath, and stem (19, 20). Deposition of $-diketone lipids is reduced or eliminated by mutants in the cer-cqu locus (20), specifically the cer-u mutants have impaired hydroxyl group insertion (19). The original cer-u.21 stock has reduced seed set (6). Morphological differences, except for surface waxes, were not observed between Bowman and its backcross-derived line BW411 (3).

Origin of mutant:

A gamma-ray induced mutant in Bonus (PI 189763) (6).

Stock number:             BGS 422

Locus name:               Eceriferum-zd

Locus symbol:             cer-zd

 

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (8).

Located in chromosome 3HL (2, 9), about 9.4 cM proximal from the uzu1 (uzu 1) locus and about 4.6 cM distal from the breakpoint in the ert-c.1 (erectoides-c) line (10, 11, 12, 13); associated with SNP markers 1_0672 to 1_0281 (positions 58.56 to 98.41) in 3H of the Bowman backcross-derived line BW160 (1), likely in 3H bin 05.

Description:

Surface wax coating on the leaf blade appears absent (wax code ++ ++ -) (8). Concerning the chemical epicuticular wax composition, the amount of wax cm-2 is reduced and is accompanied by a decrease of the size and morphological complexity of the wax bodies. The bodies are smaller, simpler, and less dense. The wax class distribution is the same as in the mother variety (14). Plants of the Bowman backcross-derived line BW160 were 10 to 15% shorter than Bowman and headed about 2 days later. Kernels of BW160 were slightly thinner and 10 to 15% lighter. Grain yields were about 2/3 of normal (3)

Origin of mutant:

A neutron induced mutant in Bonus (PI 189763) (8).

Previous nomenclature and symbolization:

None.

Inheritance:

Monofactorial recessive (4).

Location in chromosome 1H, associated with SNP markers 1_0764 to 1_0552 (positions 61.55 to 88.33 cM) in 1H of the Bowman backcross-derived line BW176 (1), in 1H bins 06 to 08.

Description:

Surface wax coating on the spike appears absent, the wax coating on the leaf sheath and stem is reduced (wax code - + ++) (4). Leaf blades become golden yellow at or shortly after heading and later necrotic spots develop on the upper surface of the blade (3). The necrosis was observed in selections from crosses to Bowman, but this trait was not retained in the Bowman backcross-derived line BW176. Other significant deviations from the Bowman phenotype were not observed in BW176 (2).

Inheritance:

Monofactorial recessive (7, 8, 9).

Located in chromosome 5HL (11, 12), near the srh1 (short rachilla hair 1) locus (12); between the ert-n (erectoides-n) and the lax-a (laxatum-a) loci (11), but widely different estimates of their distance from the srh1 (short rachilla hair 1) locus are reported (6, 11); associated with SNP markers 1_0974 to 1_0641 (positions 41.99 to 108.33 cM) in 5H of the Bowman backcrossed-derived line BW189 (1); associated with SNP markers 3_0745 to 1_0641 (positions 99.51 to 108.33 cM) in 5HL of the Bowman backcross-derived line BW605 (1), likely in 5H bin 06.

Description:

The spike is branched from the rachis of the bottom 1 to 10 spikelets. Awns, which vary from normal to thread-like, and protruding branches are bent in various directions because of "packing" problems in the boot (7). More spike branches develop from rachis nodes under favorable environmental conditions.

Stock number:             BGS 474

Locus name:               Laxatum-a

Locus symbol:             lax-a

 

Previous nomenclature and gene symbolization:

Laxatum-01 = lax-01 (5, 9, 14).

Laxatum-a = lax-a01 (15).

Inheritance:

Monofactorial recessive (10, 14).

Located in chromosome 5HL (10, 13), about 2.4 cM proximal from the ari-e (breviaristatum-e) locus (7, 16), and about 3.1 cM from the ert-g (erectoides-g) locus (7, 15, 16); associated with SNP markers 2_1065 to 2_1275 (positions 40.91 to 104.73 cM) in 5H of the Bowman backcross-derived line BW457 (lax-a.8) and SNP markers 1_0621 to 2_1275 (positions 56.40 to 104.73 cM) in 5H of the Bowman backcross-derived line BW458 (lax-a.ap) (2), in 5H bin 08.

Description:

Florets have five anthers with two developing from transformed lodicules (5, 18); however, the extra anthers are deficient in having two rather than four microsporangia (1). The grain is thin and angular and caryopses are exposed between the lemma and palea. The awn has a very wide base, without a distinct notch in the lemma attachment region. Rachis internodes are about 15% longer than normal. Tillers arise at oblique angles giving isolated plants an appearance of a tufty growth habit (9). Treatment of leaves after tillering with GA3 increases rachis internode length (17). Plants of Bowman backcross-derived line BW457 are 4/5 of normal height and anthesis is delayed by 3 to 4 days. Awns can be slightly shorter than those of Bowman. Kernels are generally short and thin and highly variable in size. Compared to Bowman, BW457 plants had kernel weights about 60% of normal, test weights were low, and grain yields were about half of normal (4).

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (4).

Located in chromosome 1HS (1), near the tip of 1H associated with SNP markers 3_0969 to 3_0918 (positions 0.0 to 17.27 cM) in 1HS of the Bowman backcross-derived line BW141 (1), likely in 1H bin 01 or 02.

Description:

Surface wax coating on the leaf blade appears absent on the upper three leaves (wax code ++ ++ -) (4). Plants of the original stock are semidwarf (about 3/4 normal height), but those of the Bowman backcross-derived line were not. Changes in the expression of other morphological trait were not observed in the Bowman backcross-derived line BW141 (2).

Origin of mutant:

A neutron induced mutant in Bonus (PI 189763) (3).

Mutational events:

cer-yj.667 (NGB 111155, GSHO 1543) in Bonus, -yj.1217 (NGB 112105) in Kristina (NGB 1500) (3); cer-yj.937 (NGB 111825) in Bonus (5); cer-yj.1150 (NGB 112038) in Kristina, -yj.1811 (NGB 117359) in Bonus (6).

Mutant used for description and seed stocks:

cer-yj.667 in Bonus (NGB 111555, GSHO 1543); cer-yj.667 in Bowman (PI 483237)*3 (GSHO 2214); cer-yj.667 in Bowman*4 (BW141, NGB 20567).
