Development of a Sinitic Clubroot Differential Set for the Pathotype Classification of Plasmodiophora brassicae.

ABSTRACT: Plasmodiophora brassicae, which is known for its broad genetic diversity for virulence, is the causal agent of clubroot disease of Brassica crops worldwide. Studies on pathotype characterization with four differential hosts according to Williams' classification system showed the predominance of pathotype 4 in China. However, the genetic variability within pathotype 4 complicates the breeding of durable clubroot-resistant (CR) cultivars. Herein, a Sinitic clubroot differential (SCD) set was developed using a set of eight differential inbred lines of Chinese cabbage with known or novel CR genes. The presence of immense diversity within pathotype 4 of Williams' system was verified, and 11 pathotypes were characterized using the developed SCD system. The scalability and pr
