Goals of the USDA Regional Small Grain Genotyping Laboratories
1) Develop new molecular marker technologies; 2) Implement effective strategies for their application in breeding for small grain crops; 3) Provide breeders the access to sophisticated and state-of-the-art molecular technologies; 4) Maximize the efficiency of small grain breeding programs to speed up the process of new cultivar release.
Crops include soft red and white winter wheat, specialty-purpose wheat, winter barley and winter oats.
We focus on the following main traits for molecular genotyping: 1) Quality traits related to protein functionality, sprouting resistance, milling and baking quality in wheat; 2) Resistance to production risks, including resistance to powdery mildew, Hessian fly, Septoria tritici and Stagonospora nordorum, Fusarium head blight, and leaf, stem and stripe rust in wheat; resistance to crown rust and winter injury in oats; and, resistance to barley yellow dwarf virus in wheat and oats.
