为了明确黑龙江省第三、四积温带玉米种植新区主栽玉米品种抗大斑病特性及产量潜力，以黑龙江省讷河市为玉米新区代表，对该地区推广的16个玉米品种抗大斑病特性及产量进行了评价。结果表明：不同玉米品种对大斑病的抗性表现存在显著差异，病情指数变化范围为4．81～36．30。玉米抗大斑病表现好的品种（病指≤15）为众单1号、齐山2号、龙单39等；中等抗病表现的品种（15＜病指≤30）为德美亚2号和龙单29；抗性表现较差的品种（病指＞30）为绥玉19；不同玉米品种按产量大致可分三个等级，即高产品种为齐山2号、海玉11号和甘玉2号等；中产品种为克单14、众单1号和哈丰3号等；低产品种为德美亚2号和绥玉13。从抗大斑病和产量水平综合分析，供试的16个玉米品种中齐山2号、海玉11和甘玉2号3个品种表现最佳，德美亚2号表现最差。

In order to clarify resistance against northern leaf blight and yield of different maize varieties in the third and fourth accumulative temperature belts (planting new area)of Heilongjiang province ,sixteen maize va-rieties were used to analyze resistance against northern maize leaf blight and yield in Nehe city which could re-present new areas planting maize in Heilongjiang province .The results showed that the resistance of different maize varieties had significant difference ,disease index varied from 4 .81 to 36 .30 .Sixteen varieties were grouped into three resistant levels ,the high resistant cultivars(disease index≤15)included Zhongdan 1 ,Qishan 2 ,Longdan 39 and so on .;The moderate resistant cultivars (15< disease index ≤30)included Demeiya 2 and Longdan 29 ;The low resistant cultivars (disease index > 30)included Suiyu 19 .And they were grouped into three levels according to maize yields ,the high-yield cultivars included Qishan 2 ,Haiyu 11 and Ganyu 2 and other ;the moderate-yield cultivars included Kedan 14 ,Zhongdan 1 and Hafeng 3 and other six varieties ;the low-yield cultivars included Demeiya 2 and Suiyu 13 .Comprehensive analysis on resistance against northern maize leaf blight and yield evatution ,the results showed that three varieties (Qishan 2 ,Haiyu 11 and Ganyu 2) appeared to be the best ,Demeiya 2 appeared to be the worst .
