摘　　要：为选育抗根肿病大白菜新品种,根据"复等位基因"遗传假说及大白菜对根肿病的抗性由1对显性核基因控制的结论,以抗根肿病大白菜甲型雄性不育"两用系"的不育株为抗源和不育源,以‘黑叶’大白菜为轮回父本,经过杂交、连续回交、自交、测交、兄妹交和抗病接种筛选鉴定等方法,将抗根肿病基因和核不育基因导入‘黑叶’大白菜中,获得抗根肿病‘黑叶’大白菜新甲型雄性不育"两用系"和"临时保持系"。抗根肿病的大白菜雄性不育系的育成,为抗根肿病新品种选育提供参考。In order to breed new Chinese cabbage variety with anti-clubroot, according to the genetic hypothesis of multi-allele and the conclusion that the anti-clubroot is controlled by a dominant nuclear gene in Chinese cabbage, the resistant gene against clubroot disease and the sterile genes were transferred to‘Heiye’ Chinese cabbage with cycle male parents using anti-clubroot sterile plants of AB lines （type Ⅰ） of Chinese cabbage as resistance resources and infertility resources. By means of crossing, consecutive backcrossing, self-crossing, test cross, sib-mating and resistance inoculation screening, etc., anti-clubroot new AB lines （type Ⅰ） and temporary maintainer lines of‘Heiye’Chinese cabbage were achieved. Breeding the male sterility lines of‘Heiye’Chinese cabbage with anti-clubroot can lay the foundation for selection of new varieties in anti-clubroot.
