| Abstract: | Creation and abortive mechanism of new male sterile lines are hot-topics on Chinese cabbage breeding．F1 hybrid crossing Brassica allohexaploid（AABBCC，n=27），which owns A，B and C chromosomes simultaneously，with Chinese cabbage variety of‘Jinchun’was obtained．Then the F1 as a male parent was crossed with Chinese cabbage variety of‘Yihe No. 5’．Thus male sterile MS200712 was founded due to multiparents crossing．MS200712 owned yellow petal and light-yellow anther．The anthers were regressive，which were 100% male sterility．Stigma of MS200712 was normal and nectaries were vigor. Meanwhile 832172，male parent of‘Beijingnew No. 3’was crossed with MS200712，and male sterile MS20071208-916 was obtained． |
