Abstract

Abstract

Significant differences in freezing resistance and winter hardiness occurred between the F3 populations of certain reciprocal crosses in oats (Avena sativa L. and A. byzantina K. Koch). Heritabilities were high and selection for both freezing resistance and winter hardiness should be effective. Specific combining ability of parents and differences among F3 lines within crosses were important sources of variation for winter snrvival, but general combining ability, maternal effects, and reciprocal effects over all populations were relatively unimportant. The contribution of parents was consistent over locations, but lines within crosses were inconsistent over locations. Transgressive segregation for winter hardiness was common in the F3 populations derived from crosses between the winter and spring parents.
