摘　　要：选用新疆推广较好的主要玉米品种15个,采用随机区组试验设计,进行产量和相关农艺性状的分析,鉴定新疆自育玉米品种和国外玉米品种的产量潜力和机械化种植的适应性,比较国内外品种在农艺性状方面的差异,明确新疆进一步提高玉米育种水平的主要方向。结果表明:国外玉米品种比国内自育品种熟期早,抗倒伏、抗倒折性强,籽粒灌浆脱水速率快,结实性好,其中先玉335、KWS2564等几个品种籽粒产量高、熟期早、抗倒伏性强、出籽率高,是适宜新疆机械化种植的优良品种。This study was to identify the yield potential and mechanical planting adaptability of cultivars of spring maize introduced from Xinjiang and overseas, to compare Xinjiang spring maize cultivars with the introduced maize for agronomic traits, and to make clear the direction for improving spring maize in Xinjiang. The differences of yield potential and agronomic traits from 15 spring maize cultivars were analyzed by randomized block experiment design. The results showed that the spring maize from overseas had earlier maturity, stronger resistance to lodge, faster grain filling and better bear fruit than domestic maize. The cultivar of XIANYU335 and KWS2564 were suitable for mechanical planting in Xinjiang.
