The experiment materials are CMS line 75-3369A, restore line 7269-10 and F2 population and F3 family of 75-3369A/7269-10 combination. The F2 fertile isolations data of continuous three years were analysed.

• 以细胞质雄性不育系75-3369A、恢复系7269-10及75-3369A/7269-10组合的F_2群体和F_3群体为材料,连续三年对F_2的育性分离情况进行了统计,并结合F_3家系的育性分离情况对恢复基因的遗传规律进行了分析。
