USDA is awarding $5 million to a consortium of scientists at 19 institutions led by the University of Minnesota to identify genes that produce higher yielding, higher quality, disease-resistant barley, according to a Department statement released Friday.The goal is to develop and use the tools of genomics to develop new barley cultivars. Scientists will develop a detailed genetic "road map" of barley and proceed to identify genes linked to important traits with molecular markers in 10 breeding programs across the country. Molecular markers are landmarks in the chromosome maps that help plant scientists identify specific chromosome segments.Researchers will use the science of association genetics to identify genes controlling yield, food and malt quality, and disease resistance. Association genetics deals with evaluating and measuring the degree of association between the molecular markers (genes) and the traits of interest.Marker-assisted selection technology allows breeders to more precisely select the best trait combinations for specific varieties. For example, a plant scientist might mark a combination of genes known to increase disease resistance. Breeders wanting the disease resistance trait use marker information to identify lines containing that specific combination of genes.In addition, education and outreach will be integral component of the project. Students will be included in all aspects of the projects to ensure the next generation of plant breeders is educated. Data and results will be available to scientists, growers and industry through the project's public Web site at www.barleycap.org.
