摘　　要：为避免盲目引种,指导当地农业生产,对黑龙江省高纬地区的16个玉米品种,在82500株·hm^-2密度下的综合农艺性状和产量进行评价。结果表明:可以将参试品种划分为3个熟期,由于植株倒伏和病害情况建议淘汰品种4个,产量超过10000 kg·hm^-2的有先达101、华美2号、吉龙99和富单9号,产量9000~10000 kg·hm^-2的品种有4个,产量8000~9000 kg·hm^-2的品种有7个,产量低于8000 kg·hm^-2的仅有吉盛1号一个品种,产量为7850.10 kg·hm^-2,但其熟期最早,适合极早熟地区种植。In order to avoid blind introduction and guide local agricultural production,the comprehensive agronomic characters and yield of 16 maize varieties in high latitude area of Heilongjiang Province were evaluated under 82500 plant·hm^-2 density.The results showed that the tested varieties were divided into 3 mature periods.Due to plant lodging and diseases,4 varieties were recommended to be eliminated,and 4 varieties with yield over 10000 kg·hm^-2 were Xianda 101,Huamei No.2,Jilong 99 and Fudan No.9,with yield of 9000-10000 kg·hm^-2.There are 7 varieties with a yield of 8000-9000 kg·hm^-2,and only one variety,Jisheng No.1,with a yield of 7850.10 kg·hm^-2,had a yield lower than 8000 kg·hm^-2.However,it had the earliest maturity and was suitable for planting in extremely early maturing areas.
