摘　　要：通过利用经纯合的甘蓝型油菜雄性不育系117AB与6个菜薹品种进行远缘杂交,对其F1的有效结荚率和亲和指数进行分析,研究117AB与十字花科菜薹品种间的远缘杂交亲和性.结果表明:117AB的远缘杂交亲和性,对于不同十字花科菜薹品种表现出较大的差异性.117AB与菜心品种的杂交亲和性较差,而与红菜薹品种的亲和性较好;117AB×十月红菜薹、117AB×改良十月红及117AB×优选十月红等杂交组合的杂交亲和性较好,其F1具有较高的有效结荚率.117AB, a homozygous male sterile line of rapeseed （Brassica napus L. ）, was crossed with 6 different vegetable varieties of Cruciferae, and the effective podding rates and compatibility indexes of the Fls were analyzed. Remarkable differences in compatibility were observed in different cross combinations. The crosses of llTAB with B. carnpestris ssp. chinensis vat. Purpured Hort had the greatest compatibility, while compatibility was the poorest between B. campestris and 117AB.
