摘  要:
为了评价不同小麦品种(系)对麦二叉蚜的抗性,应用每株麦苗上接1头蚜虫的方法,在温室内用5个指标(发育历期DD、成虫与幼虫的体重差WD、成虫在与发育历期相等时间内的产子数F、相对日均体重增长量MRGR和成虫在与发育历期相等时间内的日均产仔数Rm)测定了10个小麦品种对麦二叉蚜的抗性,并以此为基础用多元方差分析法、多目标综合判别法和聚类分析法评价了这10个小麦品种(系)对麦二叉蚜的抗性,结果表明,Amigo最不适于麦二叉蚜在其上取食,抗性最好,Batis抗性较好,其他品种抗性较弱。

摘  要:
In order to evaluate the resistance of different wheat varieties to greenbugs (Schizaphis graminum),5 biological parameters,including development days(DD),weight difference between the 1st instar larvae and adults(WD),fecundity(F),mean relative growth rate(MRGR) and daily average of offspring-producing(Rm) of greenbugs feeding on the seedlings of 10 wheat varieties(lines) were studied by inoculating 1 aphid to 1 wheat seedling in glasshouses.The resistance of these wheat varieties(lines) to greenbugs was estimated in 3 ways,i.e.multivariate variance analysis,multi-object integrated synthesis and "Ward" cluster analysis.The results showed that the wheat variety Amigo was most resistant to greenbugs,followed by Batis,but other varieties were only slightly resistant.
