[目的]筛选出适宜阿勒泰地区种植的青贮玉米品种。[方法]2013年在阿勒泰地区挑选5个青贮玉米品种，进行田间品比试验，比较各品种生育期、主要农艺性状和产量。[结果]参试玉米品种的生育天数为113～134 d，除新饲玉12号生育天数为134 d、新贵1号生育天数为125 d外，其余3个品种生育天数相差不大；参试玉米品种株高从高到低依次为新饲玉12号、隆牧1号、新贵1号、新青1号、SC704；参试玉米品种产量由高到低依次为新饲玉12号、隆牧1号、新贵1号、新青1号、SC704；新饲玉12号、隆牧1号以及新贵1号产量均在100500 kg／hm2以上。[结论]隆牧1号品种适应性较强，产量较高，表现较好，适宜在阿勒泰地区大面积推广。%Objective] To screen the silage corn varieties suitable for Altay Region.[Method] Five silage corn varieties were selected in Altay in 2013,the growth period,main agronomic traits and yield were compared.[Result] The growth days of tested silage corn varieties were from 113 to 134 days.Except that the Xinsiyu 12 was 134 d and Xingui 1 was 125 d, other three varieties showed little differences in growth days.Plant height of tested silage corn varieties were in the order of Xinciyu 12, Longmu 1, Xingui 1, Xinqing 1 and SC704.Yield of tested silage corn vari-eties were in the order of Xinciyu 12, Longmu 1, Xingui 1, Xinqing 1 and SC704.Among them, yields of Xinciyu 12, Longmu 1 and Xingui 1 were all above 100 500 kg/hm2.[Conclusion] Longmu 1 has relatively strong adaptation, yield and performance, which is suitable to be extended in Altay Region.
