Estimation of Combining Ability, Hybrid Vigor, and Gene Action for Protein in Avena spp. L.1

H. W. Ohm and F. L. Patterson2

Six Avena sterilis L. introductions, all high in groat protein, were crossed as paternal parents to five A. saliva L. commercial genotypes to estimate combining ability, hybrid vigor, types of genetic effects, and heritability for percent groat protein and protein yield.

F1 hybrids produced a lower percent groat protein than the midparental value. Percent groat protein was maintained from F1 to F2. Contrastingly, a large amount of hybrid vigor existed for protein yield in the F1 but was reduced in F2. General combining ability was highly significant for percent groat protein in paternal and in maternal parental groups. Paternal x maternal interaction effects were generally nonsignificant. Each of the A. sterilis parents appeared to have similar proportions of dominant and recessive genes for percent groat protein when in combination with the given set of A. sativa genotypes Partial dominance for low protein was usually indicated. High percent groat protein was recessive in all crosses. Percent groat protein was highly heritable. Protein yield, dependent on seed yield, had low heritability values. Percent groat protein tended to be negatively correlated with seed yield, although the correlation was low and nonsignificant.

Key Words: Oats • Exotic gernplasm • Percent protein • Protein yield
