“…Fitzroy is a relatively new cultivar, gaining malting classiWcation in 2005. Of particular interest was the feed cultivar, Valier, which was released in 2002 as a speciWc cattle feed quality cultivar by Montana State University (Blake et al 2002). Prior to release, feed trials demonstrated that cattle had increased daily weight gain when fed on this cultivar compared to other breeding lines (Boss and Bowman 1996).…”

“…However, from a breeding perspective it is still unclear as to the deWnitive range of values for grain traits that would have a direct and positive inXuence on animal performance. To date, only one "feed" quality cultivar (Valier) with claims of a direct improvement in animal performance has been released (Blake et al 2002). Particle size, ADF, starch and in-sacco dry matter digestibility (ISDMD) were considered to be four factors inXuencing performance (Bowman et al 2001).…”

Grain samples from a combined intermediate and advanced stage barley breeding trial series, grown at two sites in two consecutive years were assessed for detailed grain quality and ruminant feed quality. The results indicated that there were signiWcant genetic and environmental eVects for "feed" traits as measured using grain hardness, acid detergent Wbre (ADF), starch and in-sacco dry matter digestibility (ISDMD) assays. In addition, there was strong genotypic discrimination for the regressed feed performance traits, namely Net Energy (NE) and Average Daily Gain (ADG). There was considerable variation in genetic correlations for all traits based on variance from the cultivars used, sites or laboratory processing eVects. There was a high level of heritability ranging from 89% to 88% for retention, 60% to 80% for protein and 56% to 68% for ADF. However, there were only low to moderate levels of heritability for the feed traits, with starch 30-39%, ISDMD 55-63%, ADF 56-68%, particle size 47-73%, 31-48% NE and ADG 44-51%. These results suggest that there were real diVerences in the feed performance of barleys and that selection for cattle feed quality is potentially a viable option for breeding programs.

“…F 2 plants were advanced to the F 5 generation by SSD in the greenhouse, and F 5 -derived families were grown under field conditions. Valier is a two-rowed, hulled spring barley cultivar developed by the Montana Agricultural Experiment Station (Blake et al 2002), while PI370970 is a six-rowed hulless line selected from the USDA world collection of barley's spring core collection based on its low ISDMD value, large PS, high starch content, and low ADF content (Bowman et al 2001). In total, 116 F 5 -derived families, parents, and check varieties were planted at the A.H. Post Research Farm (Amsterdam silt loam soil) near Bozeman, Montana during the 2002 and 2003 cropping seasons.…”

“…Bowman et al (2001) suggested that selection for low ISDMD, low ADF, larger PS after rolling, and higher starch content will help the barley breeder improve feed quality. Based on these criteria, variety Valier was recently released by the Montana State University Experiment Station, and it is the first barley variety to have documented data on feed quality prior to its release (Blake et al 2002).…”

Quantitative trait loci for dry matter digestibility and particle size traits in two-rowed × six-rowed barley population

et al. 2009

More than half of the barley grown in the USA is used for livestock feed, with the remaining stocks diverted for human food and malting purposes. The use of barley grain as a major source of cattle feed has been criticized because of its rapid digestion in the rumen, which can result in digestive disorders in cattle. In sacco dry matter digestibility (ISDMD) and particle size (PS) after dry rolling have been found to play a role in the feedlot performance of barley as a feed grain. Reducing the rate of ISDMD is predicted to result in significantly improved animal health and average daily gain. A recombinant inbred line population derived from a cross between a high ISDMD, two-rowed barley cultivar (Valier) and a sixrowed Swiss landrace line (PI370970) exhibiting far slower ISDMD has been developed for studying the underlying genetic locations and mechanisms of these traits. To detect associated quantitative trait loci (QTLs), we collected and analyzed data from irrigated and rain-fed environments. A significant negative correlation was observed between ISDMD and PS. High heritability estimates for ISDMD and PS suggest that early selection for these traits during breeding would be achievable. Four QTLs were identified on chromosomes 2H, 6H, and 7H, explaining 73-85% of ISDMD phenotypic variation, while three QTLs on 2H and 7H were associated with variation in PS and explained 58-77% of its variation. A major QTL on chromosome 2H tightly linked to the morphology-modifying gene vrs1 was found to dramatically control 35-62% of the phenotypic variation of ISDMD and 26-53% of that of PS. The impact of the vrs1 locus on ISDMD was validated in two populations representing different genetic backgrounds. Our results suggest that it may also be advantageous to simultaneously overlap these QTLs around the vrs1 locus.

“…As this resource expands, we will find interesting and uniquely useful alleles of many genes that, when assembled into appropriate genetic backgrounds, will result in breakthrough varieties of barley, wheat, oats, and rye. This has already been accomplished in barley (Hayes et al, 2000;Blake et al, 2002;Castro et al, 2003) and is rapidly being implemented by the world's wheat and oat improvement communities.…”

GrainGenes 2.0. An Improved Resource for the Small-Grains Community

GrainGenes (http://wheat.pw.usda.gov) is an international database for genetic and genomic information about Triticeae species (wheat [Triticum aestivum], barley [Hordeum vulgare], rye [Secale cereale], and their wild relatives) and oat (Avena sativa) and its wild relatives. A major strength of the GrainGenes project is the interaction of the curators with database users in the research community, placing GrainGenes as both a data repository and information hub. The primary intensively curated data classes are genetic and physical maps, probes used for mapping, classical genes, quantitative trait loci, and contact information for Triticeae and oat scientists. Curation of these classes involves important contributions from the GrainGenes community, both as primary data sources and reviewers of published data. Other partially automated data classes include literature references, sequences, and links to other databases. Beyond the GrainGenes database per se, the Web site incorporates other more specific databases, informational topics, and downloadable files. For example, unique BLAST datasets of sequences applicable to Triticeae research include mapped wheat expressed sequence tags, expressed sequence tag-derived simple sequence repeats, and repetitive sequences. In 2004, the GrainGenes project migrated from the AceDB database and separate Web site to an integrated relational database and Internet resource, a major step forward in database delivery. The process of this migration and its impacts on database curation and maintenance are described, and a perspective on how a genomic database can expedite research and crop improvement is provided. ) and oat (Avena sativa) crops to plant breeders, pathologists, geneticists, and molecular biologists (Matthews et al., 2003). Originally conceived as a stand-alone database, GrainGenes now encompasses an integrated database and Web site, working intensively with the smallgrains research community to provide an Internet portal for numerous ancillary projects for Triticeae genetics and contributing to the development of informatics tools to support small-grains research. Like many other organism-focused databases, GrainGenes concentrates on genomic aspects; however, it is also an important repository for information concerning genetic resources, pathology, and colleagues.The GrainGenes Database initially was operated using AceDB (http://www.acedb.org), a platform adopted by many early genome projects. AceDB served the GrainGenes project's needs very well with powerful schema, query languages, graphical displays, and the simplicity to be operated completely by a single biologist. The object-like data structures of AceDB worked well for handling the diverse underlying data, enabling straightforward connections between all data types and allowing the schema to be changed easily to accommodate new kinds of data. The AceDB software continued to develop and improve for several years and still has an active user community, providing an excellent resource for biological database deve...
