Nine white clover varieties (Haifa, Huia, Super Huia, Zapican, G18, Emu No.1, Kersey, Pitau and Crau) were selected as sample materials, and the test of seed germination under 10% PEG 6000 osmotic stress and the pot incubation test of water stress and rewatering were detected respectively. The drought tolerance was evaluated by weighted fuzzy membership functions. The results showed seed germination were inhibited in PEG 6000 osmotic stress, but the tolerance of these germination indices to PEG 6000 stress is different, in which vigor index and germination index were inhibited significantly, germination potential and germination rate were inhibited slightly. The indexes of higher weight in the evaluation of PEG stress at the germination stage were relative root volume, relative root surface area, and relative vigor index. The responses of seedlings in different varieties to drought stress varied greatly. Root growth of most white clover varieties were inhibited by drought stress. The indexes of higher weight at the seedling stage were the survival rate, relative root volume, and relative dry weight of aboveground biomass. The order of drought tolerance of 9 white clover varieties at the germination stage was Haifa, Huia, Super Huia, Zapican, G18, Emu No.1, Kersey, Pitau and Crau. The order of drought tolerance at the seedling stage was Kersey, Super Huia, Crau, Huia, Emu No.1, Zapican, Haifa, G18 and Pitau. There was no correlation between the orders of drought tolerance at the germination stage and at the seedling stage. Super Huia had the best drought resistance.
