2007 Annual Report 1a.Objectives (from AD-416) Using genomics tool to. 1)screen agronomically important wheat traits in hard winter wheat from five breeding programs in southern Great Plains, 2) speed up process of incorporation of important genes into commercial wheat cultivars and shorten cultivar release time, and identify QTL for important wheat traits and associated markers for marker-assisted selection. 1b.Approach (from AD-416) Use of high throughput molecular marker technology to identify desirable genes from breeding materials, haplotype breeding parents and provide useful information to help breeders to make breeding plan, map QTL for agronomically important traits, and identify high-throughput markers for traits of breeders' interest and use them for marker-assisted selection. 3.Progress Report This report serves to document research conducted under a reimbursable agreement between ARS and the University of California-Davis, and associated with the Wheat Coordinated Agricultural Project (CAP). Additional details of this research can be found in the report for the parent project 5430-21000-005-00D, Genetic Enhancement for Resistance to Biotic and Abiotic Stresses in Hard Winter Wheat. The objectives of this study were to implement high-throughput marker assisted selection strategies in regional breeding programs to speed up the breeding process and enhance selection efficiency. In 2006, wheat elite lines from the Northern and Southern Regional Nurseries were analyzed for 22 traits using a total 40 molecular markers. In addition, about 10,000 samples were analyzed and generated a total of 49,800 marker data points for the CAP project. Progress on this agreement is monitored by regularly discussing program goals, approaches, and results (on site) and by reviewing annual accomplishments reports.
