Quantitative Trait Locus Mapping of Clubroot Resistance and Plasmodiophora brassicae Pathotype Banglim-Specific Marker Development in Brassica rapa.

ABSTRACT: Clubroot resistance is an economically important trait in Brassicaceae crops. Although many quantitative trait loci (QTLs) for clubroot resistance have been identified in Brassica, disease-related damage continues to occur owing to differences in host variety and constant pathogen variation. Here, we investigated the inheritance of clubroot resistance in a double haploid population developed by crossing clubroot resistant and susceptible lines "09CR500" and "09CR501", respectively. The resistance of "09CR500" to Plasmodiophora brassicae pathotype "Banglim" was controlled as a single dominant gene, with the segregation of resistance and susceptibility being nearly 1:1. PbBrA08Banglim was identified as having a logarithm of odds value of 7.9-74.8, and a phenotypic variance of 26.0-97.1% with
