摘　　要：用具有 Ogura胞质雄性不育基因的花椰菜雄性不育材料 NYAcms为母本 ,不同花椰菜品种为父本 ,通过连续 6代回交选育 ,育成异源胞质雄性不育系 C5 0 - 2及其相应的保持系 5 0 11- 2。C5 0 - 2不育系具有生长发育正常、抗病、农艺性状优、配合力好等特点 ,通过组合配制试验 ,初步筛选出 2个优良组合在生产上示范推广。Cauliflower alloplasmic cytoplasmic male sterility line C50\|2 was obtained at the sixth generation through backcross and selection by use of cauliflower male sterility MYAcms which contains oguracytoplasmic male sterility genes as female parent and different kinds of carliflower as male parent. Its maintenance line was 5011\|2. C50\|2 was noted for normal growing,disease resistant,well agronomy characters and high combining ability. Two excellent hybrid combinations were obtained and demonstrated and popularized.
