Twenty-five cruciferous vegetable varieties,including 19 Chinese cabbage varieties,3 cabbage varieties,3 radish varieties,with resistance to clubroot were concentratedly demonstrated in Changyang County Yichang City and Lichuan City of Hubei Province.The results showed that the pathogenicity of Changyang Plasmodiophora brassicae is much stronger than Lichuan Plasmodiophora brassicae.Majority of the Chinese cabbage cultivas were anti-resistant to Changyang Plasmodiophora brassicae,but resistant to Lichuan Plasmodiophora brassicae,only‘Jingchun CR2’and‘Jingchun CR3’were resistant to the both,and their comprehensive economic characters were excellent.They can be extended in Changyang,Lichuan and similar regions,where have the same clubroot pathogenicity.The other Chinese cabbage cultivas with single resistance to clubroot can be extended in Lichuan and similar regions also.Radish variety‘Xuedan No.3’in Changyang was tolerant to this disease and in Lichuan was resistant variety.Its comprehensive economic characters was good.Cabbage variety‘2012070’was tolerant to clubroot in Changyang,but all tested cabbage varieties were not resistant to Lichuan clubroot disease.
