Clubroot is a devastating soil-borne disease caused by the obligate biotrophic pathogen Plasmodiophora brassica (P. brassicae), which poses a great threat to Brassica oleracea (B. oleracea) production. Although several QTLs associated with clubroot resistance (CR) have been mapped in cultivated B. oleracea, none have been cloned in B. oleracea. Previously, we found that the wild B. oleracea B2013 showed high resistance to clubroot. In this study, we constructed populations using B2013 and broccoli line 90196. CR in B2013 is quantitatively inherited, and a major QTL, BolC.Pb9.1, was identified on C09 using QTL-seq and linkage analysis.
