Abstract: By using the techniques of laboratory bioassay, this paper studied the effects of 0.5 mmol/L of cadmium on the germination rate, germination index, vigor index, root length, shoot height and fresh weight of root and shoot to assess the cadmium-resistant ability of wheat by the synthetical effect with 30 wheat varieties mainly cultivated in the province of Guizhou. The results showed that after treated with 0.5 mmol?L-1 of cadmium, seed germination rate was less affected, but germination index, vigor index, root and shoot growth were restrained evidently. Cadmium had more serious impact on root than on shoot. Different wheat varieties had different germination responses to cadmium. Based on their responses to cadmium, the test 30 varieties were clustered into 3 types, ie, tolerant type, medium type, and sensitive type. Fengyou 5, Zaomai 16 and Fengyou 970 were tolerant to Cd and the sensitive varieties include Anmai 5, Chuanmai 10, Fengyou 2 etc.
