Technical Abstract: Cultivated oat (Avena sativa) is an important food and feed crop worldwide. The North Dakota State University breeding program has been developing new oat varieties over the last century that have high yield potential and improved nutritional composition. To accelerate the rate of genetic gain and build molecular tools for breeding, we performed a genome wide association study with advanced breeding germplasm. We evaluated 1095 lines over the course of four years and identified several genomic regions that influence traits of interest such as yield, protein, oil, beta-glucan, and crown rust resistance. Validated molecular markers that flag these regions of interest are now available for screening larger populations to predict these traits and accelerate the release cycle of new and improved lines.
