摘　　要：[Objective] This study aimed to meet the demand of farmers for highyielding, high-quality, wide-adaptability and multi-resistant new maize cultivars, and to make food production grow continuously. [Method] Comparative test of new maize cultivars was conducted at different altitudes in 2015, and the yield, main economic characters, agronomic traits, growth period and resistance of maize cultivars were analyzed. [Result] Ruidan 26 and Yongrui 16 can be cultivated in the areas below the altitude of 2 200 m; Huaxingdan 88 can be cultivated in the areas below the altitude of 1 750 m; the other new maize cultivars still need to be tested further. [Cenclusion] The research results can be applied in this area and other similar areas, which will effectively promote the upgrading of maize cultivars and improve the yield per unit area.[目的]满足粮农对高产、优质、广适和多抗玉米新品种的需求,使粮食持续增产。[方法]2015年通过不同海拔地区玉米新品种田间对比试验,对玉米产量、主要经济性状、主要农艺性状、生育期和抗逆性等指标进行分析。[结果]芮单26和永瑞16可以在海拔2 200 m以下地区推广种植;华兴单88可以在海拔1 750m以下地区推广种植,其它品种需进一步试验。[结论]该研究结果在该地区和其他类似地区推广应用,将有效促进玉米品种更新换代,提高单位面积产量。
