영문 초록

A seven-parent diallel cross of rice was analyzed for fatty acid compsition of phospholipid from leaves. The analysis of variance revealed that differences among parents and F₁ hybrids were highly significant for fatty acid. The variances of parent vs. F₁ hybrids were highly significant for all characters except for linoleic acid. Both general and specific combining ability were highly significant and non-additive genetic variance predominated for fatty acid. In the F₁ generation, over dominance was observed for all fatty acids. Direction of dominance was positive for unsaturated fatty acid, whereas it was negetive for saturated fatty acid. The number of effective gene groups was estimated as one for palmitic acid and stearic acid, and two for oleic acid and linolenic acid. Broad sense heritability was fairly high but narrow sense heritability was low.
