摘　　要：以白梗白菜雄性不育材料NY8481为不育源,以青梗白菜自交系709 311等为转育父本,通过杂交和连续回交选育出优良的青梗白菜胞质雄性不育系709 311A,利用其配制的组合709 311A×801 112具有很强的杂种优势。The original male sterile source from the Chinese cabbage-pak-choi with white petiole [Brassica campestris L. ssp.chinensis(L.) Makino var. communis Tsen et Lee] NY8481 was transferred to Chinese cabbage-pak-choi with green petiole inbred line 709-311. A new excellent cytoplasmic male sterile line 709-311A was obtained by crossing and backcrossing. A hybrid using 709-311A crossing with 801-112 shows good growth vigor and higher yield.
