摘要: 通过田间抗旱鉴定试验,采用模糊函数法对不同玉米杂交组合的抗旱性进行综合评价,并进一步通过品比试验研究各组合的丰产性,结果表明:411×18599、苏11×449、79-1E×S7913、交51×411、5311×449、5311×S1-1、18599×1125、交51×5311、411×S1-1、S1-1×449和79-1E×449等组合的抗旱性和丰产性表现较好,抗旱性在Ⅲ级中抗以上,产量达80907.70 kg/hm2,是抗旱高产杂交组合,可以在生产上加以应用。

Abstract: We analyzed and evaluated the drought resistance of several hybrid maize materials by method of subordinate function values. We compared their fertility by field test. The result showed that 411×18599、苏11×449、79-1E×S7913、交51×411、5311×449、5311×S1-1、18599×1125、交51×5311、411×S1-1、 S1-1×449和79-1E×449 all had an field average 8090.70 kg/hm2 and drought resistance above level Ⅲ. They can be all extended as high-yield material with drought resistance.
