영문 초록

The diallel analysis was conducted with F₁ and F₂ population derived from crossing in all combinations without reciprocals among six rice cultivars, three tropical japonica and three japonica types, with different panicle number and panicle length. The expression was controlled by additive gene action with partial negative dominance in panicle number and partial positive dominance in panicle length. Epistasis was not recognized for the two characters. The narrow-sense heritability was estimated at 92% for panicle number and 82% for panicle length. GCA effects were larger than that of SCA in both characters. There were significant correlations between F₁ and F₂ generation on the ranks of parents GCA effects.
