Abstract:According to the distribution of physiological races of Plasmodiophora brassicae in Jiangxi province, field disease nurseries were set up in race 4 distribution area in Wuyuan county and race 9 area in Nanchang county respectively. From September to December 2016, the resistance of 108 cruciferous vegetable varieties to clubroot in the field was identified, and 29 species of them were randomly selected for resistance identification by artificial inoculation. As the results show, there were resistance differences between different interspecies varieties of cruciferae to different races of Plasmodiophora brassicae, and different intraspecific varieties also had resistance difference to the same race of Plasmodiophora brassicae. All varieties of cauliflower, cabbage and radish were resistant to race 9 of Plasmodiophora brassicae. Pakchoi varieties Shanghaiheiyewuyueman, Xinnaibai, Jinglvwutacai and 13 chinese cabbage varieties, such as Jingxiawang, Beijingjuhongxin and Jingchunwa No.2 were resistant to race 9 of Plasmodiophora brassicae. Although the tested varieties were less resistant to race 4 of Plasmodiophora brassicae, ten cauliflower varieties, such as Jinhua 6, Jinhua 16, and Songhua 2 and radish variety Mantanghong which can be grown in race 4 areas were screened out.
