Abstract：Taking the existing anti-clubroot CR9112A and CR9112B lines of straight canister folded common Chinese cabbage〔Brassica campestris L. ssp. pekinensis（Lour）Olsson〕as female parent and stably inherited‘Longyuanhong No.1’JH-1 inbred lines of Chinese cabbage with orange head as male parent, we prepared every generations of F1, F2 and BC1F1. The inheritance rule of‘Longyuanhong No.1’inbred lines was verified, and the relationship between clubroot resistance gene with orange head leaf gene was explored. The identification results showed that there was no linkage relationship between clubroot resistance and orange head characteristics, and these 2 were independently inherited. The gene type of‘Longyuanhong No.1’JH-1 was msmsrrhh. On this basis, the paper put forward a genetic model for transferring clubroot resistance to orange head traits, so as to obtain an excellent orange head Chinese cabbage resistant to clubroot.
