Abstract: The study was conducted to research six sugarcane varieties’response to drought stress in seedling period in Yunnan, to determine their drought resistance. The tested sugarcane varieties were planted with pots by using artificial water control to cause drought stress condition, the physiological indices such as soluble sugar, praline content, chlorophyll content, malondialdehyde content (MDA), moisture content and plasma membrane permeability were measured. Fuzzy membership functions and the cluster analysis method for multiindex comprehensive analysis were adopted to evaluate the drought resistance of the six sugarcane varieties. The results indicated that‘Mintang69-421’showed strong drought resistance,‘ROC22’and‘Guitang11’ showed moderate drought resistance,‘Yuetang93- 159’,‘Yuetang86- 368’and‘Dianzhe01- 58’showed weak drought resistance.
