Research Project: Oat SNP Development and Identification of Loci Affecting Key Traits in North American Oat Germplasm and Crown Rust Testing

Location: Small Grains and Potato Germplasm Research

Project Number: 5366-21000-028-28
Project Type: General Cooperative Agreement

Start Date: Apr 01, 2011
End Date: Mar 31, 2013

Objective:
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.

Approach:
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; 1) heading date, 2) plant height, 3) lodging, and 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: 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.
