摘　　要：利用萝卜细胞质甘蓝雄性不育系 ,对不同类型的青花菜材料进行转育 ,获得了萝卜胞质青花菜雄性不育系BC7 19。该不育系不育性稳定 ,不育率及不育度均达 10 0 % ;不育系的蜜腺大小与其转育父本相近 ,能吸引蜜蜂等昆虫采蜜传粉 ,而且 ,不育系具有正常的雌蕊 ,功能健全 ,结实能力强 ;同时 ,不育系园艺性状与其保持系相近 ,基本无苗期低温黄化现象 。A radish cytoplasmic male sterile line, BC7 19, in broccoli (Brassica oleracea L.var. italica Plenck.) was obtained by crossing and backcrossing from male sterile materials with radish cytoplasm of cabbage, whose sterility was stable, the percentage of sterile plants and the sterility percentage were 100%. The nectary size was not obviously different from the backcross male parents, and the nectary can attract bees and other insects pollinating. Meanwhile, the male sterile line, which is identical to its maintainer in horticultural traits, is characterized by normal pistil with good seeding capability.
