摘　　要：通过研究不同玉米品种在黄土高原丘陵沟壑区的稳产性及丰产性,以期为该区玉米新品种的筛选及推广提供科学依据。以引进10个玉米品种为试材,对参试各玉米品种的农艺性状、产量及产量特征等指标进行综合分析评价。结果表明,强盛399、伊丹131、金穗1915折合产量高,分别为11850.1、11605.0、11411.9 kg/hm2,较对照品种金穗702分别增产14.54%、12.17%、10.30%;并单39、丰田101、敦玉9号折合产量较低,分别较对照品种金穗702减产3.76%、10.86%、30.76%。利用综合评价法对参试玉米品种进行综合评价并结合产量结果表明,强盛399、金穗306、伊丹131、金穗702表现出良好的丰产性与稳产性,同时表现出静态稳定性高、品质优异、生态适应性强的特点,是适用于黄土高原丘陵沟壑区种植的玉米新品种,建议予以推广。金穗1915、FT806、强盛388综合评价居中,建议继续引种观察。敦玉9号、丰田101、并单39号综合评价较差,建议淘汰。This study evaluated the stability and productivity of different maize varieties in the hilly and gully areas on the Loess Plateau to provide a scientific basis for the selection and promotion of new maize varieties in the area.10 introduced maize varieties were tested for agronomic traits,yield,and yield characteristics.The results showed that Qiangsheng 399,Yidai 131,and Jinsui 1915 had high average yields of 11850.1,11605.0,and 11411.9 kg/ha,respectively,representing increases of 14.54%,12.17%,and 10.30%over the control variety Jinsui 702.On the other hand,Bingdan 39,Fengtian 101,and Dunyu 9 had lower yields,showing decreases of 3.76%,10.86%,and 30.76%compared to that of Jinsui 702.Comprehensive evaluation combined with yield data showed that Qiangsheng 399,Jinsui 306,Yidan 131,and Jinsui 702 exhibited excellent productivity and stability,along with high static stability,superior quality,and strong ecological adaptability,making them suitable for cultivation in the hilly and gully areas on the Loess Plateau.They are recommended for promotion.Jinsui 1915,FT806,and Qiangsheng 388 received middle evaluation remarks and are recommended for continued observation.Dunyu 9,Fengtian 101,and Bingdan 39 were rated poorly and are recommended for elimination.
