摘　　要：为筛选出适应当前玉米密植与机械化快速发展需求的玉米品种,对12个早熟玉米杂交种在我国北部高寒区的适应性进行了综合分析。结果表明:YN1409和JC18两个品种在供试品种中比较突出,较对照有明显增产,熟期相当,在其它各方面没有明显缺点;LKY901和BD8两个品种除产量略低于对照外,没有其它明显问题,尚需进一步验证。The adaptability of 12 early maturing maize hybrids in the northern high latitude cold region of China were analyzed in order to screen out the maize varieties adapting to the rapid development mechanization and close planting.The results showed that yield of YN1409 and JC18was higher than control,maturation stage similar to control,two varieties were no obvious shortcomings in the other aspects;LKY901and BD8 two varieties in addition to the yield were slightly lower than the control,there was no other obvious problem,it still need further verification.
