- 摘要:
- 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 varieties were used to analyze resistance against northern maize leaf blight and yield in Nehe city which could represent 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
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.
