对甘蓝型双低油菜细胞质雄性不育系384A的不育性表现、遗传方式等方面的研究结果表明,该不育系属败药型不育,其败育彻底,育性稳定,花瓣开张正常,不育性的遗传受不育细胞质(S)和一对隐性核不育主效基因(RR)共同控制,属孢子体不育,基因型为S(R),同时也受若干位点上微效基因的影响.“,”In the study,the performance of double low CMS 384A on cytoplasmic male sterile was observed and analysed It has been found that the cytoplasmic male sterility of CMS 384A belongs to typical anther spoilable sterile type Anthers spoiled completely Petals stretch normally The male sterile was stable The cytoplasmic male sterile of CMS 384A belongs to sporophytic sterile type,and its male sterility is derived from the interaction of a cytoplasmic sterile gene (S) with a pair of recessive nucleus genes (...
