Abstract: The objective of this study was to use 2 gene molecular markers of clubroot resistance from Chinese cabbage (SC2930 and KBrH129J18R), to identify clubroot resistance genes in 78 resources of Chinese cabbage.The results showed that there were 34 resources with SC2930 resistance marker in 78 resources.Including 17 heterozygous loci materials and 17 homozygous loci materials.37 resources had KBrH129J18R resistance marker.Including 22 heterozygous loci materials and 15 homozygous loci materials.20 resources hadn't the resistance markers of CRa or CRb.23 resources had both 2 resistance markers.The study defined the clubroot resistance gene types of CRa and CRb in the 78 resources, and provided a material basis of breeding for clubroot resistance in Chinese cabbage.
