Abstract：Willimas identification system was applied to identify 2 bacter ia samples of clubroot（Plasmodiophora brassicae）collected from Anning and Yuxi in Yunnan Province. The results showed that the host reactions on both 2 bacteria samples were identical to that on No. 4 physiological race. Eighteen Chinese cabbage〔Brassica campestris L. ssp. pekinensis（Lour）Olsson〕varieties with clubroot-resistance were introduced from domestic and oversea districts，and were planted with the medium inoculated No. 4 physiological race of clubroot. The results showed that ‘CR-huimin’，‘Kanggen 51’and‘Tainengshugen’were resistant to fungus，and the disease rate were 0，0 and 4%，respectively. This indicated that they can be used as resistant resources to breed new disease-resistant materials. Meanwhile，field identification results showed that‘CRhuimin’and‘Kanggen 51’had good economic characters and could be applied and popularized in clubroot prevailing regions of Anning and Yuxi in Yunnan Provin ce.
