The use of clubroot resistance (CR) genes is an effective and economical approach for controlling Plasmodiophora brassicae, the causal agent of clubroot disease in Chinese cabbage (Brassica rapa) and other Brassica crops. In a previous study, we identified and mapped the CRb locus on chromosome A03 of B. rapa in the doubled-haploid (DH) line ‘CR Sh...

In Chinese cabbage (Brassica rapa), the clubroot resistance (CR) gene CRb is effective against Plasmodiophora brassicae isolate No. 14, which is classified as pathotype group 3. Although markers linked to CRb have been reported, an accurate position in the genome and the gene structure are unknown. To determine the genomic location and estimate the...

In Chinese cabbage (Brassica rapa), the clubroot resistance (CR) genes Crr1 and Crr2 are effective against the mild Plasmodiophora brassicae isolate Ano-01 and the more virulent isolate Wakayama-01, but not against isolate No. 14, classified into pathotype group 3. 'Akiriso', a clubroot-resistant F(1) cultivar, showed resistance to isolate No. 14. ...
