Abstract: 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.
