The peanut varieties（lines） were subjected to mild, moderate, and severe drought stress during the peanut pod setting period using a potted method（with normal water supply as the control）, and the dry matter quality of roots and pods was measured during the peanut ripening period. Evaluate and analyze the drought resistance of 22peanut varieties through the yield drought resistance coefficient method and variety comprehensive index method.According to yield-drought coefficient and composite index the peanut varieties were divided 3 grade. The most adaptable varieties in arid regions were Kainong1768, Shanhua11, DF31, L52, kainong65, CTWE, Huayu662,Fuhua27, Jihua16, Yuanza9102. The stronger adaptable varieties include Huyu962, Puhua28, S51, FB4, Huyu20,Luhua15. The poor adaptable varieties include L107, Weihua13, Fuhua22, Huayu27, Luohua6, Jihua4. On severe stress can be more accurate evaluated of the peanut varieties compared with the 3 intensity.
