Clubroot resistance gene Rcr6 in Brassica nigra resides in a genomic region homologous to chromosome A08 in B. rapa

Abstract

Rcr6 was the first gene identified and mapped in the B-genome of Brassica species. It resides in a genomic region homologous to chromosome A08 of A-genome. Based on this finding, it could possibly integrate into A08 of B. napus using marker assisted selection with SNP markers tightly linked to Rcr6 developed in this study.
