Research Project: OAT SNP DEVELOPMENT & IDENTIFICATION OF LOCI AFFECTING KEY TRAITS IN NORTH AMERICAN OAT GERMPLASM USING BYDV & CROWN RUST TESTING
2011 Annual Report


1a.Objectives (from AD-416)
The objective of this research will be to evaluate the oat association mapping population for resistance to barley yellow dwarf virus (BYDV) and crown rust.


1b.Approach (from AD-416)
This report documents research conducted under a Grant Agreement between ARS and the PURDUE UNIVERSITY. Additional details for the research can be found in the report for the parent project 5366-21000-028-00D, SMALL GRAINS GENETICS AND GERMPLASM ENHANCEMENT. Over the past 48 years world-wide oat production has declined 58%, while production of crops like corn and soybean have drastically increased. Research groups in North America actively working on oat have also declined from 28 (1998) to 11 (2008). The Collaborative Oat Research Enterprise was recently established by the USDA-ARS in Aberdeen, Idaho as an international scientific collaboration to reverse these trends. As part of the project, ARS Aberdeen enlisted the help of the North Dakota State University breeding program to evaluate 685 oat lines for key characteristics improving plant production, including resistance to various diseases; milling efficiency; and health value. Over the last year (2010 – 2011), Field evaluations in two North Dakota locations (Casselton and Fargo) have yielded key information on agronomic and disease characteristics enabling the development of genetic “signpost” for the traits on the map. Seed harvested from Casselton, North Dakota is currently being milled and tested for grain antioxidant and fiber levels. Once these experiments are complete, signpost for each of the genetic locations controlling these characteristics will be added to the map. To date, several signpost have been developed and are being used by the North Dakota State University breeding program as a genetic “GPS” to expedite the development of improved oat varieties. This work will allow target development of high beta glucan lines possible in oat. This work directly relates to the current ARS Aberdeen project plan (5366-21000-024-00D) “Develop improved barley and oat cultivars meeting the needs of conventional and specialty markets for both dryland and irrigated production systems”, objective 2. Monitoring of the project is accomplished via site visits, phone conversations, email, and written reports.
