Abstract: Water deficit is one of the major limitation for the production of winter wheat in arid region and semiarid region of China. Wheat in the jointing stage is very sensitive to the lack of water. Therefore,this experiment was conducted under two different water treatment(Normal and mid drought) with Xinong 979 and other 6 cultivars in pot. The superoxide dismutase(SOD) activity,peroxidase(POD) activity,catalase(CAT) activity,relative electric conductivity,MDA content,the soluble sugar content,the soluble protein content and the proline content were measured as physiological indices for evaluating the drought resistance. The results showed that under drought stress,the activities of SOD,POD and CAT,relative electric conductivity,MDA content,the soluble sugar content and the proline content increased at different levels,and the soluble protein content of Jinmai 47,Xiaoyan 22,Aikang 58 and Xinong 979 also increased except for other 3 cultivars. Based on the principal component analysis,the ranking of the tested cultivars was as follows: Jinmai 47 Xiaoyan 22 Aikang 58 Xinong 979 Xinong 509 Zhengmai 366 Zhengmai 9023.
