摘　　要：为了给山西省春播中晚熟玉米区"一深两增"高产模式提供适用品种,选取大丰30、大丰26、强盛51、强盛101、福盛园52、并单390、潞玉36、先玉335、郑单958和北农110共10个品种为供试材料,研究了其产量构成因素及潜力。结果表明,强盛101及大丰26产量大于16 500kg.hm-2,显著高于其他品种,且在采用"一深两增"高产模式下产量潜力分别达到19 148kg.hm-2和17 691kg.hm-2;强盛51、大丰30、福盛园52、先玉335和郑单958产量表现居中;并单390和潞玉36保苗率表现优异,均高于90%。除北农110外均可作为山西省中晚熟玉米区高水肥水浇地"一深两增"模式下的适用品种。In order to offer suitable varieties to ＇one deep and double increase＇ high yield mode in spring corn area of Shanxi Province,ten maize cultivars,including Dafeng30,Dafeng26,Qiangsheng51,Qiangsheng101,Fushengyuan52,Bingdan390,Luyu36,Xianyu335,Zhengdan958 and Beinong110,were used as the experimental materials to study the potential yield and yield components.The results showed that the yield of Qiangsheng101 and Dafeng26 were significantly higher than those of other varieties,and their yields were both above 16 500 kg·hm-2.Yield potentials of Qiangsheng101 and Dafeng26 in ＇one deep and double increase＇ high yield mode were 19 148 kg·hm-2 and 17 691 kg·hm-2,respectively.Qiangsheng51,Dafeng30,Fushengyuan52,Xianyu335 showed general yield performance.Bingdan390 and Luyu36 had excellent seedling maintained rates which were higher than 90%.In general,all varieties except Beinong110 could be used as suitable cultivars for the high water and fertilizer corn-belt in Shanxi in ＇one deep and double increase＇ high yield mode.
