垩白是一胚乳性状,表现直感遗传(xenia);F_2的分离可在 F_1稻株上的米粒观察到。要选育无垩白米的杂交稻,必需不育系、恢复系均无垩白。观察了 F_1、F_2、B_1和 F_3的垩白分离,认为垩白由二对隐性主效基因控制。
Chalky rice is an endosperm trait showing xenia; F 2 separation can be observed on rice grains on F_1 rice plants. To breed non-chalky rice hybrid rice, must be sterile lines, restore the Department of no chalkiness. The chalky separation of F_1, F_2, B_1 and F_3 was observed, and it was thought that the chalkiness was controlled by two pairs of recessive major genes.
