Locus name: Non-brittle rachis 1
Locus symbol: btr1
Previous nomenclature and gene symbolization:
Non-brittle rachis = r (7).
Inheritance:
Non-brittle rachis = b (2).
Non-brittle rachis 1 = bt1 (1).
Monofactorial recessive in crosses to Hordeum vulgare subsp
spontaneum (2, 3 7).
Description:
Located in chromosome 3HS, very close or semi-allelic to the btr2
(non-brittle rachis 2) locus (5, 6); the Btr1Btr2 complex is about 15.4
cM distal from the alm (albino lemma) locus (6).
Joints at the rachis nodes are tough or non-brittle, which prevents
segmentation or disarticulation of the rachis prior to maturity. Plants
homozygous for the btr1.a allele do not shatter prior to harvest in
contrast to wild barley (Hordeum vulgare subsp spontaneum). All
cultivars with the btr1.a allele have a dominant allele at the Btr2
locus. When crossed to cultivars with the btr2.b allele at the
Btr2 locus (genotype Btr1Btr1btr2btr2), F1 plants have a
brittle rachis. The segregation ratio in the F2 generation is 1
brittle : 1 tough rachis (5). The majority of the cultivars distributed in
Occidental region of the Old World have the btr1.a allele (4, 6).
Origin of mutant:
Probably a spontaneous mutant in Hordeum vulgare subsp
spontaneum.
Mutational events:
btr1.a in an unknown race of Hordeum vulgare subsp
spontaneum (3, 6); the line A222 (CIho 11555) is recommended as the source
line for the btr1.a gene.

Locus name: Chlorina seedling 2
Locus symbol: fch2
Previous nomenclature and gene symbolization:
Chlorina seedling 2 = f2 (9).
Inheritance:
Light green 5 = lg5 (8).
Chlorina seedling f2 = clo-f2 (5).
Monofactorial recessive (1, 2, 9).
Description:
Located in chromosome 3HL (7, 9, 10, 11), about 7.7 cM distal from the
cur2 (curly 2) locus (12).
Seedlings have a pale yellow-green color, which persists until near maturity
under greenhouse or field conditions. Development of homozygotes is delayed,
but the stunted plants survive to produce seed (1). A complete absence or
greatly reduced levels of chlorophyll b were found in mutant plants (1,
2, 5). The respiratory and photosynthetic rates of detached leaves and intact
plants are not significantly different from those of normal plants. However,
the growth rate of mutant plants decreases after the endosperm is depleted (2).
An absence of chlorophyll b-binding proteins in the photosynthetic
membranes is found in fch2 mutants (3, 4).
Origin of mutant:
A spontaneous mutant in progeny from the cross Moister (CIho 2799) X California
Coast (CIho 6115) (1).

Locus name: Low number of tillers 1
Locus symbol: lnt1
Previous nomenclature and gene symbolization:
Reduced number of tillers = rnt (3).
Inheritance:
Intermedium spike-l = int-l (2).
Monofactorial recessive (3).
Description:
Located in chromosome 3HL (3), about 30.5 cM distal from the uzu (uzu)
locus (3, 4).
The tiller number is reduced to 2 to 4 per plant. These tillers are formed soon
after seedling emergence; hence, no late-emerging tillers are observed. Culms
are thick and stiff and leaves are dark green (3). Spike malformations occur in
most environments. The spike may have irregular rachis internode lengths and is
relatively short. The lower portion of the spike appears more dense. Lateral
spikelets in two-rowed cultivars are enlarged and have a pointed apex. Plants
homozygous for a recessive allele at the lnt1 locus head slightly
earlier than normal sibs (2).
Origin of mutant:
A spontaneous mutant in the hybrid Chikurin Ibaragi 2/Miho Hadaka (3).
Mutational events:
lnt1.a in Mitake (OUJ408) (3); int-l.81 in Bonus (PI 189763) (1,

Locus name: Desynapsis 2
Locus symbol: des2
Previous nomenclature and gene symbolization:
Desynaptic chromosomes = ds (1, 2).
Inheritance:
Monofactorial recessive (1, 2).
Description:
Located in chromosome 3H (1, 2).
Synapsed homologous chromosomes disjoin precociously because of an apparent
lack of chiasmata (1). The chromosomes are paired during pachytene and undergo
desynapsis during diplotene. The degree of desynapsis is d = 6.0 +/- 3.3 with a
range from 7 ring bivalents (d = 0) to 2 rod bivalents plus 10 univalents (d =
12). Lagging chromosomes and micronuclei are observed frequently at telophase
I. Microspore tetrads contain an average of 1.8 micronuclei per tetrad and a
range of 0 to 7. Ovule fertility is about 1% and highly variable from spike to
spike on the same plant (3). The very low fertility trait occurs infrequently
in the F2 progeny from the cross to Bowman, but nearly 1/4 the
plants show reduced seed set (about 60%).
Origin of mutant:
An X-ray induced mutant in Husky (CIho 9537) (1).
Mutational events:
des2.b in Husky (1, 4).
Mutant used for description and seed stocks:
des2.b in Husky (GSHO 593).

Locus name: Zebra stripe 1
Locus symbol: zeb1
Previous nomenclature and gene symbolization:
Zebra stripe = zb (1, 4).
Inheritance:
Monofactorial recessive (1).
Description:
Located in chromosome 3HL (1, 3, 4), about 7.0 cM proximal from the uzu
(uzu) locus (2).
Seedlings may have pale green to yellow bands across the leaves when germinated
under cold conditions in the field (1). Cold room studies show that development
of the mutant phenotype in seedlings can be induced by 10 to 15 days of cold
treatment ( 0 to 1 C) if initiated within one day after wetting of the seed
(5). Alternating cold and warm temperatures in the field induce diagnostic
symptoms (5).

Locus name: Six-rowed spike 4
Locus symbol: vrs4
Previous nomenclature and gene symbolization:
Multiflorus = mul (6, 14).
Inheritance:
Intermedium spike-e = int-e (4, 8).
Six-rowed spike 4 = v4 (1).
Monofactorial recessive (1, 2, 3, 5).
Description:
Located in chromosome 3HL (3, 11, 12, 13), about 27.5 cM distal from the
uzu (uzu) locus (3).
Alleles at this locus enhance the development of lateral spikelets and
formation of additional spikelets to various degrees. The int-e mutants,
which were isolated in two-rowed cultivars, have enlarged lateral spikelets
that may set seed in the upper two-thirds of the spike. Kernels in lateral
spikelets are smaller than those from central spikelets in int-e
mutants. The rachilla may be deformed by partial formation of an extra
spikelet. The awn size on lateral spikelets range from a pointed apex to 3/4
normal length (9). The mul1.a and vrs4.k alleles, which were
isolated in six-rowed cultivars, may produce numerous extra spikelets at the
base of the lateral spikelets and on the rachilla (2, 6). Phenotypic
differences among alleles are retained in the Bowman backcross-derived lines.
Origin of mutant:
A gamma-ray induced mutant in MFB 104 (3).
Mutational events:
mul1.a (Alb Acc 321, GSHO 561) in Montcalm (CIho 7149) (6, 14);

Description:
Located in chromosome 3HL (4, 5, 6), over 6.3 cM distal from the uzu
(uzu) locus (4, 6), and about 20.5 cM distal from the uzu locus (5).
Plant height is reduced to about 1/2 to 2/3 of normal, plant development is
delayed, and plants are slightly yellow green in color (2, 5). The normal
distribution of leaves is altered because the peduncle is relatively long in
proportion to the other internodes. Plants homozygous for the sld1.c
allele are slightly weaker and shorter than sld1.a plants in their
respective Bowman backcross-derived lines.

Locus name: Early maturity 10
Locus symbol: eam10
Previous nomenclature and gene symbolization:
Early maturity sp = easp (6).
Inheritance:
Monofactorial recessive (6).
Description:
Located in chromosome 3HL (6), about 2.0 +/- 5.8 cM from the Est1-Est4
(esterase 1, esterase 4) locus (6).
In winter nurseries at Cuidad Obregón, Sonora, Mexico and Davis,
California, USA, plants of Super Precoz 2H head about 11 days earlier than
lines with the genes eam7.g or eam8.k for photoperiod
insensitivity from Atsel and Sv Mari, respectively (6). The eam10.m gene
appears to suppress expression of the eam7.g and eam8.k genes
(6). Plants expressing eam10.m become chlorotic (yellow green) under
photothermal stress. Zeaxanthin increases at the expense of chlorophyll and
other pigments (5). The chlorotic appearance is similar to that observed in
plants homozygous for other recessive genes for early maturity (eam7,
eam8, and eam9) (1, 4, 5).
Origin of mutant:
Present in Super Precoz 2H (PI 527381) from Russia (6), but originating
probably as an induced mutant in MC20 (2, 3, 5).
Mutational events:
eam10.m in Super Precoz 2H plus a dominant maturity enhancer (3, 4, 5);
eam10.m in Amber Nude without the enhancer (3).
Mutant used for description and seed stocks:
eam10.m in Super Precoz 2H (GSHO 2504); eam10.m in Amber Nude
(GSHO 2505).

Locus name: Breviaristatum-a
Locus symbol: ari-a
Previous nomenclature and gene symbolization:
Breviaristatum-6 = ari-6 (1, 2).
Inheritance:
Short awn 7 = lk7 (7).
Monofactorial recessive (2).
Description:
Located in chromosome 3HS (4, 5, 6), probably less than 2.4 cM from the
centromere (5).
A common feature of mutants at this locus is instability in the expression of
awn length, ranging from very short to 5/6 normal length in various
environments. In some environments, secondary or tertiary tillers may show a
drastic reduction in stem internode, spike, and awn length. Awns are thin and
brittle and may flare somewhat on later tillers. Kernels are thin with fine
wrinkles on the lemma (2).

Locus name: Erectoides-c
Locus symbol: ert-c
Previous nomenclature and gene symbolization:
Erectoides-1 = ert-1 (2).
Inheritance:
Monofactorial recessive (5, 6).
Description:
Located in chromosome 3HL (4, 10, 11), about 3.7 cM from the centromere (8, 9),
and about 2.9 cM proximal from the msg5 (male sterile genetic 5) locus
(1).
Spikes have a compact or semicompact appearance caused by a reduction in rachis
internode length, with values from 1.7 to 2.9 mm. The spike has a fusiform
shape with shorter rachis internodes at the base and longer ones near the apex.
The culm length is also highly variable among mutants at the ert-c
locus. Mutants ert-c.66 and ert-c.153 are partially sterile, much
shorter in culm length, and have a more bushy growth pattern than other mutants
at this locus (3, 10). GA3 treatment of plants as the flag leaf
emerges decreases spike density (12). The Bowman backcross-derived line for
ert-c.1 is later and taller than Bowman.
