摘要
利用甘蓝型油菜细胞质雄性不育系与大白菜自交可育系作远缘杂交,采用回交转育方法,将甘蓝型油菜胞质雄性不育系转育为大白菜胞质雄不育系。经过2代杂交、1代自交、4代回交,已育成经济性状优良、遗传性稳定、不育株率和不育度均达100%,且雌蕊健壮、结实良好的大白菜胞质雄不育系及其相应的保持系。
Through distant hybridization between B. campestris sytoplasmic male sterile line and B. pekinensis self-breeding line,and acompanied with backcross,a new sytoplasmic sterile line of Chinese cabbage has been transformed.It is a fully sterile line,with good plant characters stable sterility and strong pistils. The rates for both the sterile plant and sterile degree are of 100 percent,and at same time its maintainer has also been successfully bred.
