以不结球白菜细胞核基因雄性不育系向乌塌菜作物转育

摘要

试验根据大白菜复等位基因遗传假说，以不结球白菜细胞核基因雄性不育系为不育源，向乌塌菜作物中转育，并对细胞核雄性不育基因转育机制进行系统研究。获得如下结果：设计遗传转育模式，完成乌塌菜4个世代雄性不育的转育工作，获得含有乌塌菜基因型的甲型“两用系”、临时保持系和雄性不育系。%In this experiment, based on the multiple allele inheritance hypothesis of Chinese cabbage, male steriliry of non-heading Chinese cabbage GMS was transferred to Brassica chinensis (L.). The experiment has been systematically investigated the transformation mechanism of genetic male sterility. Results showed that four male sterile generations of Brassica chinensis (L.) could be achieved according to the inheritance transformation mode.
