The drought resistance of several hybrid maize materials were analyzed and evaluated by method of subordinate function values and their fertility was compared in field test. The result showed that S1-1×411, 411×79-1E, S1-1×1125, 79-1E×411, S1-1×79-1E, 79-1E×18599, 79-1E×S1-1, S1-1×5311 and S1-1×S7913 all had the yield beyond 9420kg/hm2 and drought resistance was above level Ⅲ. They can be all extended as high-yield material with drought resistance. 18599×Su 11,18599×449 and S1-1×Su 11 were adversity suscept...
