Identification of Novel Locus RsCr6 Related to Clubroot Resistance in Radish (Raphanus sativus L.).

ABSTRACT: Clubroot is a devastating disease that causes substantial yield loss worldwide. However, the inheritance and molecular mechanisms of clubroot resistance during pathogen infection in radish remain largely unclear. In this study, we investigated the inheritance of clubroot resistance in the F₂ population derived from crossing clubroot-resistant (CR) and clubroot-susceptible inbred lines "GLX" and "XNQ," respectively. Genetic analysis revealed that a single dominant gene controlled the clubroot resistance of "GLX" with a Mendelian ratio of resistance and susceptibility of nearly 3:1. Bulked segregant analysis combined with whole-genome resequencing (BSA-seq) was performed to detect the target region of RsCr6 on chromosome Rs8. Linkage analysis revealed that the RsCr6
