2010 Annual Report
1a.Objectives (from AD-416)
Conduct a two year multi-location association mapping study to develop marker-trait associations to facilitate the development of new oat varieties with superior agronomics and disease resistance.
1b.Approach (from AD-416)
Single row plots for all 685 association lines will be grown in randomized complete block design with two replications. Agronomic traits evaluated prior to harvest will include;.
4)maturity. Disease severity data will be collected at the appropriate time. Four hundred grams of seed will be harvested and sent to Aberdeen, ID for quality analysis including:.
2)percentage plump kernels,.
3)1000 kernel weight,.
5)groat color, and.
6)percentage broken groats using standardized methods. All data will be collected and analyzed for marker trait associations. Documents Grant with Louisiana State University.
The 685 oat population developed under the USDA NIFA AFRI agreement 5366-21000-028-11R and North American Millers’ Association trust agreement 5366-21000-028-18T was planted in Baton Rouge, LA. The population was grown under natural environmental conditions and agronomic data on plant height was collected for all 685 lines.
Communication and exchange of work has taken place via meetings, conference calls, and laboratory visits.
The project is funded through a reimbursable agreement with USDA NIFA AFRI and North American Millers’ Association trust.
