摘    要:在大田对18个品种98-10-34、PI-矮、千斤早、XZ1三代、AmigoF3、98-10-30、98-10-35、Tm44、98-10-9、Amigo、XZ13三代、98-10-32、AmigoF2、AmigoF4、PI-高、XZ13母本、陕229及Largo进行耐害性测定,对小麦的感蚜量做了系统调查,分别分析各品种耐害补偿功能及自然感蚜特征之间的关系。结果显示:品种Tm44、AmigoF3、Amigo、AmigoF2、AmigoF4和98-10-9虽然自然感蚜率比较高,但与同类相比减产率却不高;品种Largo、98-10-32、陕229、98-10-35、XZ13母本、PI-高和XZ1三代自然感蚜率比较低,而且其减产率也相对较低;品种PI-矮不仅自然感蚜率高,减产率也排名第二;98-10-34为明显感虫品种,还有98-10-30、XZ13三代和千斤早因为虽然感蚜率最小,但减产率相对较高,所以也是感虫品种。采用室内网罩饲养实验系统研究4个小麦品种陕229、98-10-9、Tm44和largo对麦长管蚜Macrosiphum avenae(Fabricius)生命周期及生殖情况等的影响,同时通过组建不用品种上麦长管蚜繁殖特征生命表,从量的角度揭示小麦品种抗性与麦长管蚜增长之间的关系。结果表明:不同小麦品种对麦长管蚜的存活率,发育历期和净增值率的影响明显不同,品种间抗蚜性存在显著差异。

关 键 词:小麦  麦长管蚜  抗生性  耐害性  累积存活率

Abstract:The tolerance to aphid Macrosiphum avenae(Fabricius)of 18 varieties of wheat and the quantity of aphid in the field were studied to analyze the relationship.The results showed that,(1) Although the quantity of aphid on the varieties of Tm44,AmigoF3,Amigo,AmigoF2,AmigoF4 and 98-10-9 was higher than the others,the rate of product reduction was not larger;(2) The quantity of aphid and rate of product reduction of the varieties of Largo,98-10-32,Shaan 229,98-10-35,XZ13 female parent,PI-tall and third generation of XZ1 were both lower than the others;(3) The quantity of aphid on variety of PI-short was the highest,and the rate of product reduction was second highest.(4) The variety of 98-10-34 was obviously susceptible to pests,and the varieties of 98-10-30,third generation of XZ13 and Qianjinzao were also susceptible to aphid because their rate of product reduction were relatively higher,although they were have infected fewer aphids.The influence of 4 varieties of wheat on life cycle and production of M.avenae were studied indoor.The results showed that different wheat varieties had different effects on survival rate,developmental duration and net reproduction rate of M.avenae,which indicated the significantly different resistance to aphids.
Keywords:wheat  Macrosiphum avenae  antibiosis  tolerance to pests  cumulative survival rate
