The research progress on the genetics of resistance and disease-resistant breeding of the main vegetables clubroot in Cruciferae was reviewed. In respect of inheritance of resistance, more studies about the clubroot of Brassica pekinensis and Brassica oleracea have been done, which were more concentrated on the resistance genes, molecular markers linked to CR loci and genetic mapping of QTL resistance to clubroot. The clubroot of Brassica oleracea belonged to the inheritance of quantitative trait controlled by multiple genes, and more than 20 clubroot resistance QTLs were obtained. The clubroot resistance genes of Brassica pekinensis were relatively independent, and 8 clubroot resistance genes were found. In the field of diseaseresistant breeding, the study of Brassica pekinensis was relatively thorough, and more molecular markers of the clubroot resistance were acquired. Furthermore, some resistant materials have been selected, whose commercial applications were realized. The disease-resistant pure lines of Brassica oleracea were obtained difficultly because of its complex inheritance of resistance, thus the breeding process was slow. Considering the above current situation, the research direction and possibility of cruciferous vegetable clubroot in the future were prospected.
