摘　　要：以国内收集的23份青贮玉米(Zea mays)品种为试验材料,开展了生育期、农艺性状、产量测定,并利用灰色关联度进行综合评价,旨在筛选出适合新疆昌吉地区推广种植的青贮玉米品种。结果表明:‘曲辰9号’、‘先饲玉1号’、‘大京九23’和‘屯玉168’鲜草产量在120 t·hm^(-2)以上,显著高于其他品种(P <0.05);‘曲辰9号’、‘大京九23’干草产量在37 t·hm^(-2)以上,但倒伏率也较高,倒伏严重。通过灰色关联度综合分析,筛选出适宜该地区推广种植的早熟青贮玉米品种为‘京科青贮932’、‘先饲玉1号’,中熟青贮玉米品种为‘屯玉168’、‘北农青贮3 651’,晚熟青贮玉米品种为‘禾玉36’、‘文玉3号’和‘北农青贮368’。23 varieties of silage maize(Zea mays) collected in China were used as experimental materials to measure the growth period, agronomic traits, and yield. Grey correlation analysis was used to comprehensively analyze each variety aiming to screen out silage maize varieties suitable for popularization and planting in the Changji area, Xinjiang. The results showed that the yield of fresh grass of ’Quchen No. 9’, ’Xiansiyu No. 1’, ’Dajingjiu 23’, and ’Tunyu 168’ was more than 120t·ha^(-1), significantly higher than that of other varieties(P < 0.05). The yield of hay grass of ’Quchen No. 9’ and ’Dajingjiu 23’was more than 37 t·ha^(-1). Combined with lodging rate, we found that the lodging situations of ’Quchen No. 9’ and ’Dajingjiu23’ were higher than those of other varieties. According to grey correlation analysis, suitable varieties were screened out in this area: the early maturity silage corn varieties were ’Jingke Silage 932’ and ’Xianyu1’, medium maturity silage corn varieties were ’Tunyu 168’ and ’Beinong Silage 3 651’, and late maturity silage corn varieties were ’Heyu 36’, ’Wenyu 3’ and ’Beinong Silage 368’.
