Being the first oilcrops in China, rapeseed suffered a severe infection of clubroot disease caused by Plasmodiophora brassicae, resulted in over 66.7×10_⁴ hectors of rapeseed field was affected and thus clubroot has become the first killer for rapeseed safe production. Different ways was applied for controlling this disease, and among them, breeding and cultivating of resistance varieties is regarded as the most economic and effective one. In order to accelerate the genetic improvement of rapeseed for clubroot resistance, in this study we summarized almost all the progresses made in the last decades on resistance germplasms innovation, resistance gene mapping and genetic improvement on clubroot in rapesed, at the same time some important scientific questions were raised according to the different aspects above as mentioned. In case long term of cultivation of varieties containing only single resistance gene will cause losing their resistance, thus in this study we pointed out ways of how to develop the durable resistance varieties and how to utilize them properly.
