摘　　要：选择甘蓝型、白菜型、芥菜型三种类型油菜雄性不育系和保持系分别与甘蓝型、白菜型、芥菜型油菜和芸芥进行种间杂交,研究十字花科种间杂交亲和性雄性不育细胞质遗传效应。结果表明:三种类型的不育系均有一致的趋向,即用不育系和保持系与同一亲本杂交的亲和指数,不育系作母本的明显高于以保持系作母本的组合,表明十字花科种间杂交亲和性具有雄性不育细胞质遗传效应。The male sterile lines and their respective maintainer lines of Brassica napus, B.campestris and B.juncea were chosen as the parents in interspecific crosses with B.napus, B.campestris, B.juncea and Eruca sativa in order to investigate male sterile cytoplasmic effects on the interspecific cross incompatibility. The results showed that the compatibility indexes were obviously higher when the male sterile lines were used as the female parent than when their respective maintainer counterparts were used as the female parent, indicating the male sterile cytoplasmic effects on interspecific cross incompatibilities in Cruciferae.
