Abstract:
Clubroot disease (Plasmodiophora brassicae) is one of the most damaging diseases of vegetable Brassica in the world. Different research groups from various countries of the world have identified eight clubroot resistance (CR) loci; Crr1, Crr2, Crr3, Crr4, CRa, CRb, CRc and CRk in Brassica rapa and twenty seven genetic loci encoding CR in B. oleracea by Quantitative Trait Loci (QTLs) analysis till now. Some CR loci are located in the near position of the same chromosome and others are distributed in different chromosomes. The current status of knowledge of clubroot resistance genes considering the future prospects for the development of CR resistant cultivars only are reviewed. The article provides relevant reviews on the clubroot resistant genes and their accumulation through Marker-assisted selection (MAS) in both B. oleracea and B. rapa.
