通过种间杂交将Ogura萝卜雄性不育细胞质导入了紫菜薹，通过连续回交获得了叶色正常、蜜腺正常的紫菜薹Ogura细胞质雄性不育系。将雄性不育的紫菜薹成都品种与雄性可育的武汉紫菜薹品种进行杂交，所配的四个杂交组合都比亲本表现了较强的营养生长优势，其中二早子×九月鲜不但营养体长势较好，而且抽薹较早；阴花红油菜×十月红营养生长势最强，但抽薹较晚。这两个组合都有可能在生产上得到应用。

The male sterile cytoplasm of Ogura radish was introduced into the seaweed via interspecific hybridization, and the cytoplasmic male sterile lines of normal seaweed and normal nectary of Ogura were obtained by successive backcrossing. The male sterile laver breed Chengdu varieties and male fertile Wuhan seaweed sprouts variety hybridization, the four hybrid combinations with the performance of the parents than the strong vegetative growth advantage, of which two early child × September not only nutrition The body grows well, and the bolting earlier; overcast red rape × October nutrition strongest growing potential, but bolting later. These two combinations are likely to be applied in production.
