摘　　要：在三系杂交水稻生产中,不育系的细胞质对杂种一代的表现具有一定的效应。同一种不育细胞质对不同性状的效应是不同的;不同的不育细胞质对同一性状的效应也存在着差异;且对大多数性状表现为负向效应。可通过扩大不育细胞质源以选用优质细胞质或选用强优恢复系来减少或消除其负效应,培育同核异质的多胞质不育系来适应杂交水稻生产的需要。Cytoplasm of CMS line influence the expression of F_1 of hybrid rice.The effect of a certain CMS cytoplasm on different characters of F_1 is dissimilar and different CMS cytoplasms have vary effects on a same character.Most of CMS cytoplasms present negative effects.A practical method to reduce or eliminate the negative effects of CMS cytoplasm is selecting elite CMS cytoplasm or strong restorer by broadening CMS cytoplasm base.It is necessary to breed homokaryon-alloplasm sterile line with multiple cytoplasms for hybrid rice production.
