摘要
[目的]明确齐市地区鲜食玉米品种抗大斑病的表现。[方法]在黑龙江省齐市地区玉米大斑病菌生理小种鉴定的基础上,采用自然侵染的方法测定50种鲜食玉米品种抗大斑病的表现。[结果]在该地区共鉴定出0、1、2和12共4个生理小种类型,其中以0号和l号生理小种为优势生理小种,分别占52.9%,和29.4%。50种鲜食玉米品种对大斑病的抗性表现为具有显著差异,万彩糯3号和斯达44共2个品种表现为免疫;哈糯2018、绿种糯167和小黄糯等20个品种表现为高抗;白糯1308、白糯118和阿尔银甜糯3号等18个品种表现为抗病;农种玉368、金糯262、密甜糯2号和白糯8301共4个品种表现为感病;京科糯2010、白甜糯8302和黄甜糯8401等共6个品种表现为高感。[结论]该研究为齐市地区鲜食玉米抗大斑病品种的选择和合理布局提供理论依据。
[Objective] To define the resistance type of fresh-eating corn hybrids to northern corn leaf blight.[Method] Fifty commercial fresh-eating corn hybrids to northern corn leaf blight was assessed based on identification of physiological races of Setosphaeria turcica under natural infection.[Result] The race 0,1,2,12 were found from the 17 strains collected from 5 urban areas in Qiqihar region.And,the race 0 and 1 were the dominant races with 52.9% and 29.4% of the total,respectively.There were significant differences in resistance of 50 fresh-eating corn hybrids to S.turcica. To determine resistance of the 50 commercial fresh-eating corn hybrids to northern corn leaf blight,two hybrids (Wancainuo 3 and Sida 44) showed immunity.Out of 50 hybrids,twenty commercial hybrids (Hanuo 2018,Luzhongnuo167 and Xiaohuangnuo,etc.) were high resistance.Eighteen commercial hybrids (Bainuo 1308,Bainuo 118 and Kennian1,etc) were resistance.And four hybrids (Nuozhongyu 368,Jinnuo 262,Mitiannuo 2 and Bainuo 8301) were susceptible.Meanwhile six hybrids (Jingkenuo 2010,Baitiannuo 8302 and Huangtiannuo 8401,etc.) were highly susceptible.[Conclusion] The study can provide the theoretical basis for selection and rational distribution of resistant hybrids of fresh-eating corn.
