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 milling quality.
1b. Approach (from AD-416)
Single row plots for all 685 association lines will be grown in an augmented design. Agronomic traits evaluated prior to harvest will include; 1) heading date, 2) plant height, 3) lodging, and 4) maturity. Four hundred grams of seed will be harvested and sent to Aberdeen, ID for quality analysis including: 1) groat percentage, 2) percentage plump kernels, 3) 1000 kernel weight, 4) groat plumpness, 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 Cornell University.
3. Progress Report
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 Ithaca, NY. The population is being grown under natural environmental conditions and agronomic data like lodging and heading date have been collected for all 685 lines. Communication and exchange of work has taken place via meetings. The project is funded through a reimbursable agreement with USDA NIFA AFRI and North American Millers’ Association trust.
