Summary
Avena sterilis introductions from the Middle East were useful sources of genes for improving the grain yield of adapted A. sativa cultivars for midwestern US. Introgression of genes from A. sterilis materials into A. sativa oat breeding populations was readily accomplished through a backcrossing procedure. Backcrossing successfully accomplished the recombination required to introgress complexly inherited traits. The BC1F2, BC2F2, BC3F2, and BC4F2 generations appeared to be best for selecting high-yielding transgressive segregates from the A. sativa x A. sterilis crosses.
