Since the latest overall coordinator’s report in Barley Genetics Newsletter Volume 33, not many important changes of the coordinators have been reported. I do hope that most of you are willing to continue with this work and provide us with new important information and literature search in the future. Unhappily some of the coordinators have definitely retired from their positions or they do not find the time to prepare reports because of other commitments, or they have stopped working on barley research. The coordinator for Chromosome 3H, Roger Ellis, has retired from his position at the Scottish Crop Research Institute, United Kingdom, and we need to find a replacement. Diter von Wettstein, the coordinator for Chloroplast genes has desired to pass over this duty to Mats Hansson at the Department of Biochemistry, Lund University, Lund, Sweden. He promised to make this coordination as he intensively works on these problems. The coordinators for the Inversions, Bengt-Olle Bengtsson and Torbjörn Säll, both from the Institute of Genetics at the University of Lund, Sweden, asked to resign as they are not working with barley genetic research any more. I want to take the opportunity to thank all of them for their good corporation and their reliability of sending informative reports during all the years.
At the end of June, many of us met at the 9th International Barley Genetics Symposium in Brno, Czech Republic, and during a ‘Barley Genetic Linkage Workshop’ where it got intensively discussed if the current system and trait coordination should continue in this manner. I became decided to do so but with a view towards whole genome coordination in the future. The report of this workshop will be published in this or next BGN Volume.
Problems of minor modifications of Rule 6 and 7 of Gene Nomenclature were discussed and accepted at the Barley Genetic Linkage Workshop of the 9th International Barley Genetics Symposium in Brno, Czech republic, on June 19, 2004. Rules for Nomenclature and Gene Symbolization in Barley with the additional amendments will be published in this volume. Revised lists of BGS descriptions by BGS number (Table 1) and by locus symbols in alphabetic order (Table 2) are also published in this volume.

Long et al., 2003 performed a marker regression based on a segregating population of 110 doubled haploid lines, derived from the cross ‘Mundah/Keel’. Grain yield and early dry matter production were associated with the chromosome 1H fragment containing the SSR markers Bmac32 and Ebmac501. For the chromosome 1H fragment with the AFLP markers P13/M49-251 and the SSR marker Awbma35, they found associations with growth habit, early maturity, kernel yield, kernel weight and kernel screening fractions.
Read et al., 2003 localised a QTL for heading date on chromosome 1H in 166 DH lines from a cross between the varieties ‘Sloop’ and ‘Halicon’. The QTL was localised between the SNP locus SOUISC4 and the microsatellite locus Bmac0382. The marker explained 28 % of the phenotypic variance.
Pillen et al., 2003 searched for associations between microsatellite markers and agronomic traits in 136 BC2F2 lines from an advanced backcross involving the wild barley (Hordeum vulgare ssp. spontaneum) line ‘101-23’ and the barley variety ‘Apex’. They found the following associations as expression of putative QTLs on chromosome 1H: an association between the SSR marker GMS21 and heading date, kernels per ear and kernel yield, an association between heading date and the SSR marker Bmac0213, an association between the traits heading date, plant height and lodging with the microsatellites HvALAAT, HVM20 and HVM64 and finally between the same traits and Bmag0211. For all QTLs, apart from the kernel yield related ones mentioned first, the alleles from the wild line were more favourable in relation to common breeding goals.
Mickelson et al., 2003 studied nitrogen storage and remobilization in barley leaves in a RI-population based on a cross between the two barley varieties ‘Karl’ and ‘Lewis’. On chromosome 1H, two regions of interest were detected: one QTL for “total leaf nitrogen at mid-grain fill” near the RFLP marker ABG53 and one QTL near the AFLP marker TB2122 for the traits “total leaf nitrogen at anthesis”, “total leaf nitrogen at maturity” and yield.
Teulat et al., 2003 found a locus with QTL x environment interaction for relative water content near the locus for black pericarp colour (bpc) on the long arm of chromosome 1H. The localisation was carried out in 167 recombinant inbred lines (RILs) from the cross ‘Tadmor/Er-Apm’, and based on data of humid as well as drought environments.
Also targeting towards genes of interest for barley cultivation under drought conditions, Baum et al., 2003 were localising QTL for agronomic traits under mild and heavy drought stress. The analysis was based on 194 RIL lines from a cross between the ICARDA-variety ‘Arta’ and a Spontaneum line. Five QTLs were found on chromosome 1H: one QTL near the SSR marker Bmag0105 for biological yield and plant height, on just beside for growth habit and kernel weight, but only under favourite conditions, one for biological yield and tiller number, one for growth habit and finally one QTL for kernel weight, biological yield and tiller number.
In 150 DH lines from ‘Steptoe/Morex’, Han et al., 2003 localised a QTL for acid detergent fibre (ADF). The locus was detected in the interval between the markers AGA006 and Hor2 and accounted for 23.6 % of the variation for this trait.
Three QTLs for resistance against Fusarium head blight on chromosome 1H were localised by Dahleen et al., 2003 in a DH population(75 lines) resulting from the three-way cross ‘Zhedar 2/ND9712//Foster’. Those three QTLs were environment-specific.
In an attempt to analyse the relation of stoma density and “avoidance” against Puccinia hordei, Vaz Patto et al., 2003 localised QTLs for the respective QTLs in a population of 100 F2 plants derived from a cross between two Hordeum chilense accessions. On chromosome 1H, they detected a QTL for “avoidance”. There was no correlation between stoma density and “avoidance”.
Madsen et al., 2003 described the development and localisation of Resistance Gene Analogues (RGAs) for barley. On chromosome 1H, three RGAs were localized: two (S-9217 and S-112, both between the RFLP locus MWG55 and the SSR locus Bmag0211) in the mapping population ‘1B-87/Vada’ (Backes, et al., 2003) and one (S-9240B, between the RFLP markers PSB67 and WG518) in the mapping population ‘Igri/Triumph’ (Laurie et al., 1995).
In the above mentioned mapping population derived from a cross between the Spontaneum-line ‘1B-87’ and the barley variety ‘Vada’ (121 RI lines), Backes et al,. 2003 localised a QTL for quantitative resistance against powdery mildew (caused by Blumeria graminis) acting additively in the field experiment at or nearby the Mla locus conferring qualitative resistance against the same disease.
Collins et al. used four different mapping populations for the localisation of QTLs for malt extract: a DH-population from the cross ‘Sloop/Alexis’ (Barr et al., 2003), a RI-population from the cross ‘Sloop-sibling/Alexis’ (Barr et al., 2003), a DH-population from the cross ‘Galleon/Haruna Nijo’ (Karakousis et al., 2003) and a DH-population from the cross ‘Chebec/Harrington’ (Barr et al., 2003). On chromosome 1H, they detected two QTLs: one near the centromere in the mapping populations Sloop/Alexis’ (near the microsatellite locus Ebmac0501) and ‘Sloop-sibling/Alexis’ and one on the long arm in ‘Chebec/Harrington’ (near the RFLP locus BCD508).
Clancy et al., 2003 localised QTLs for beta-amylase activity simultaneously in the three segregating populations derived from the crosses ‘Steptoe/Morex’, ‘TR306/Harrington’ and ‘Harrrington/Morex’, ranging from 144 to 150 doubled haploid (DH) lines. In two of the three crosses, they found a major QTL for beta-amylase activity on the short arm of chromosome 1H close by the Hor1 locus. An additional minor QTL for beta-amylase activity and diastatic power was detected on the same chromosome, but only in ‘Steptoe/Morex’.
In a DH population of 65 lines from the cross ‘Tallon/Kaputar’, Cakir et al., 2003 localised a QTL for diastatic power on chromosome 1H.

Dahleen et al., 2003 and Mesfin et al. 2003 published papers on the inheritance of resistance to Fusarium head blight (FHB), incited primarily by Fusarium graminearum Schwabe), in crosses between two- and six-rowed barley. Quantitative trait loci (QTL) for FHB resistance were again reported to occur in chromosome 2H. The reports identified three QTLs for FHB resistance and two coincident QTLs for deoxynivalenol (DON) accumulation in chromosome 2H. One QTL is near the vrs1 (six-rowed spike 1) locus and another is near the Eam6 (early maturity 6) locus. The late two-rowed parents had QTLs for FHB resistance. Mesfin et al., 2003 reported that the largest heading date effect associated with the Eam6 gene was observed in a fall greenhouse nursery.
Krasheninnik and Franckowiak, 2003 studied that FHB resistance in the Harrington/Morex (HM) doubled-haploid population and found the largest QTL for FHB resistance in chromosome 2H. The map developed for the HM population by Marquez-Cedillo et al., 2001 was used in the analysis of data. A QTL for early heading in China, a short-day environment, was at the same position in chromosome 2H as the heading date QTL reported for long-day response. This suggests that Eam6 influences heading date in both long- and short-day environments. A preliminary report by Franckowiak et al., 2003 suggests that Eam6 is ineffective in New Zealand where days are slightly longer than 12 hours at planting.
Tanno et al., 2002 used molecular marker cMWG699, which is very close (01. cM) to the vrs1 locus, to study the origins of cultivated six-rowed barley. Based on marker differences, they divided six-rowed barleys into two distinct groups, types I and II. Type I is widely distributed while Type II is found only in the Mediterranean region. Since both types exist among two-rowed barley cultivars, six-rowed barley probably originated from at least two independent mutations at the vrs1 locus.
Ayoub et al., 2002 studied kernel size and shape in the HM doubled-haploid population. They found a large QTL for kernel size associated with the vrs1 locus. The two-rowed cultivar, Harrington, had larger kernels than the six-rowed cultivar, Morex. Similar results on 1000-kernel weights were reported by Hori et al., 2003 using another two- by six-rowed population of F9 recombinant inbred lines. These results with previous studies that found pleiotropic effects of vrs1 alleles on kernel size.
Weerasena et al., 2003 reported on the conversion of amplified fragment length polymorphism (AFLP) marker P13M40 to a co-dominant marker for Rph15 (reaction to Puccinia hordei 15) locus in chromosome 2HS. This gene conferred resistance all expect one isolate in a collection of over 350 P. hordei isolates (Fetch et al., 1998). The leaf rust resistance gene Rph15.ad was shown to be an allele of the gene Rph16.ae, which was identified by Ivandic et al., 1998 in wild barley (Hordeum vulgare ssp. spontaneum).
Backes et al., 2003 identified a QTL for resistance to powdery mildew (Blumeria graminis f. sp. hordei) in chromosome 2HS and a QTL for leaf rust (Puccinia hordei) resistance in chromosome 2HL. The study was conducted using the progeny of a cross between ‘Vada’ and wild barley accession 1B-87 from Israel.
Decousset et al., 2000 reported on the development of sequence tagged site (STS) primer pairs for the Ppd-H1 or Eam1 locus in chromosome 2HS. Plants with the Eam1 gene are very early when grown under long-day conditions (Tohno-oka et al., 2000).
Canci et al., 2003 identified a minor QTL for kernel discoloration in chromosome 2H. However, two major QTLs for kernel color were found in chromosome 6H and one of these was coincident with a major QTL for high grain protein from ‘Chevron’.
Li et al., 2003 mapped 127 new microsatellite markers in barley. One of the four large clusters of makers that they found was in chromosome 2H.
Arru et al., 2003 mapped a QTL for resistance to leaf stripe (Pyrenophora graminea) in chromosome 2H of ‘Steptoe’. The QTL is at a different position in chromosome 2H than the Rdg1 locus, which also confers resistance to leaf stripe of barley.

The seed dormancy loci SD1 and SD2 of Steptoe barley have previously been mapped to chromosome 7 (5H) (Han et al., 1996). SD2 had been mapped to a 8cM interval between markers ABC 309 and MWG851 at the distal end of the long arm (Ullrich et al., 1996). This locus was subsequently fine mapped to a 0.8cM interval using a substitution mapping approach. The flanking markers were MWG 851D and MWG 851B (Gao et al., 2003). There was probably another dormancy QTL in the ABG 496 - MWG 851C interval of 5H that reduced the dormancy effect of SD2.
The locus Ba YMV/Ba YMV-2, that provides resistance to the two strains of barley yellow mosaic virus from the barley variety Chikurin Ibaraki was mapped to chromosome 5H. Three SSR markers, Bmac 0306, Bmac 0163 and Bmac 0113 cosegrated with the resistance locus. It was concluded that the resistance locus is included in a 4.3cM interval spanned by the three markers (Werner et al., 2003).
It is interesting to note that the barley yellow mosaic resistance locus rym3 has previously been mapped to chromosome 5H (Saeki et al., 1999). The resistance locus was obtained from barley line Ea52. The latter is a gamma ray induced mutant of the variety Chikurin Ibaraki.

Three studies examined polymorphisms among various genotype collections. Russell et al., 2003 sampled landraces from Syria and Jordan and tested polymorphism with 21 SSRs. One of the chromosome 7H SSRs tested showed three alleles while the other SSR locus had 31 different alleles in the 125 landrace accessions genotyped. Sjakste et al., 2003 examined microsatellite allele inheritance in the 37 European ancestors of seven Latvian varieties. The 14 SSRs tested from chromosome 7H two to seven alleles, and an average polymorphism information content (PIC) value of 0.62, a bit above the overall PIC average of 0.57. Allelic pedigrees were constructed to trace the genetic route of each current allele back to the specific ancestral source. Lund et al., 2003 used SSRs to evaluate potential duplicate groups in gene bank collections. The 35 primer pairs tested, six from chromosome 7H, identified 22 homogeneous groups among the 36 groups studied, providing a rapid method for identifying duplicates.
Pillen et al., 2003 conducted a QTL analysis of a BC2F2 population between an H. v. spontaneum and the recurrent spring barley Apex. QTLs for heading date, harvest index, malt tenderness, yield, height, thousand-grain weight, water absorption, and above ground biomass were located on chromosome 7H. Many of the favorable alleles for these important traits were from H. v. spontaneum. Matus et al., 2003 developed recombinant chromosome substitution lines by backcrossing an H. vulgare subsp. spontaneum accession to Harrington barley. They then used 47 SSR markers to determine the percentage of spontaneum introgressed into the lines. The average length of the donor segment in chromosome 7H was 39.0 cM, with segregation distorted towards the donor’s DNA. Baum et al., 2003 tested recombinant inbred lines from another H. v. spontaneum cross, with Arta. They developed a linkage map on 189 markers, including 24 on chromosome 7H. QTLs located on this chromosome included those for grain yield, 1000-kernel weight, days to heading, plant height, beta-glucan content, biological yield, and cold damage. Only the QTL for cold damage was significant in more than one environment. SSRs were used with genomic in situ hybridization (GISH) to evaluate wheat x barley backcross-derived lines (Malysheva et al., 2003). One BC1 plant contained only two small 7H fragments which were not transmitted to the progeny. The other plant contained the complete chromosome 7H. Only the end of the short arm was detected in BC2 progeny. Similar patterns of elimination were observed for other chromosomes.
Several groups reported on the development of additional markers. Li et al., 2003 developed 127 new SSR markers from genomic clones. Nine of the SSRs were located on chromosome 7H. Thiel et al., 2003 developed 76 new SSR markers from EST database information; seven were on chromosome 7H. Kota et al., 2003 also used EST collections to identify single nucleotide polymorphisms (SNPs) in barley. Of the 28 SNPs mapped in this study, three were on chromosome 7H. Another type of marker, based on NBS-LRR class resistance gene analogs (RGAs), was developed and mapped by Madsen et al., 2003. Three of these RGAs mapped to chromosome 7H.
Placement of morphological markers on the molecular maps continued. Pozzi et al., 2003 mapped 29 developmental mutants using RFLP-AFLP techniques. Both the lks2 gene for short awns and the sld4 gene for slender dwarf 4 were placed on the Proctor x Nudinka AFLP map of chromosome 7H. Dahleen et al., 2003 identified linkages between SSR markers on chromosome 7H and the lks.o and bra-a.001 morphological genes. Kikuchi et al., 2003 fine-mapped the naked caryopsis gene, nud, using bulked segregant analysis and AFLP markers. The nud locus was mapped within a 1.5 cM region and cosegregated with two AFLP markers. Their data show that nud is further from the centromere than previously reported.
Gene mapping reports also included those involved in disease response. Chen et al., 2003 compared genomic locations of rice and barley QTLs for resistance to rice blast. The 12 QTLs in barley included three on chromosome 7H. One of these loci was syntenic to a locus on rice chromosome 8. One of the QTL maps for Fusarium head blight (FHB), developed by Mesfin et al., 2003, identified several FHB QTLs, but only detected one small QTL for resistance in the greenhouse on chromosome 7H. Rostoks et al., 2003 isolated and mapped genes homologous to maize hypersensitive-induced reaction (HIR) genes. Hv-hir4 was located on the short arm of chromosome 7H in bin 03. This genes was similar to the other three HIR genes at the amino acid level, but not at the sequence level.
QTL analysis of recombinant inbred lines from a 2-rowed by 6-rowed spring barley cross was conducted using a map developed using the high efficiency genome scanning system (Hori et al., 2003). This system allowed map construction in six months, and QTLs for plant height and spike exertion were located on chromosome 7H. Teulat et al., 2003 located QTLs for relative water content in field-grown barley. One QTL representing main and QTL x E effects and one QTL that was detected only in one environment were located on chromosome 7H. Clancy et al., 2003 conducted comparative mapping of beta-amylase activity QTLs among the three mapping populations from the North American Barley Genome Project. Both populations involving Morex showed coincident QTLs for beta amylase and diastatic power on chromosome 7H. This region contains several other QTL for malting quality. QTLs for kernel discoloration and grain protein content were located by Canci et al., 2003. Two QTLs for kernel discoloration located on chromosome 7H were detected in a single environment, explaining 6.4-10.1 % of the variation for this trait. No regions on this chromosome were associated with grain protein content.

Integrating Molecular and Morphological/Physiological Marker Maps

During the past year I have attempted to integrate the Morphological /Physiological/ Disease resistance markers into the molecular Bin map. The results were sent to GrainGenes to produce an integrated map. My goal is to produce an interactive map that would incorporate pictures of markers that are “photogenic”, decriptions of markers, high resolution maps where available, BAC clone addresses, etc. The results can be viewed at http://ceres.plbr.cornell.edu/cgi-bin/gbrowse. This is obviously a work in progress, but to date it is not very viewer friendly or easy to navigate through, but the information is there. For those who would prefer the information in a less cumbersome form I reproduce it here, minus the pictures and high resolution maps, of course.
Please advise me if you have additions or corrections to this information.
