영문 초록

This study was conducted to find out the genetic characters for chalkiness of rice kernels from partial diallel crosses with four varieties. Values of genetical components were estimated by diallel analysis in F₂ seeds and distributions of the degree of chalkiness were observed. Clear was incomplete dominance to chalky with one major gene and additive gene effect was higher than dominant gene effect. Heritability was very high in both narrow and broad sense. Bi-modal distributions with dominance for clear grain were shown in Japonica × Japonica and Indica × Indica crosses, while Japonica × Indica crosses showed only higher number of grains distributed to the clear. Transgreessive segregations were found to the chalky side in clear × clear cross and Botheclear side in chalky × chalky cross.
