Resistance of the major commercial rape varieties in Yunnan Province and seven clubroot resistant rape varieties from other rape breeding institutions in China was studied in the Gaohai village, Banqiao town, Longyang region, Baoshan city in 2010 where the clubroot spread most extensively. The results showed that the Plasmodiophora brassicae were aggravated by artificial simulating waterlogging at seeding stage, while the yield was reduced greatly. The clubroot harmed rape from seedling period and was most severe at bolting stage while the disease index and disease incidence reduced at silique mature period. The sixteen rape varieties were divided into three classes according to their resistance to the clubroot. Tress varieties A35, Huayou No.7, Yunyoushuang No.1 showed high resistance during all growth period and could be used as dominant breeds for further study on resistant breeding.
