摘 要 ：在1985—1990年,对584个大豆品种(系)进行了抗蝇性研究。经初筛、复筛,最后筛选出4个抗性较好的品种,以豫豆2号抗性最好。并测定了大豆品种(系)对豆秆黑潜蝇的扰生性、耐害性。分析了17种氨基酸与抗性的关系;对大豆不同品种主茎进行切片检查发现,髓部直径与主茎直径比值(X_1)、木质部厚度与主茎直径比值(X_2)与侵入虫量(Y)关系密切。其多元回归方程为:log■=1.3499+0.1694X_1-2.0719X_2

Abstract:The resistance of 584 soybean varieties and lines to soybean stemborer MeIanagromyza sojae(Zehntner)were studied in 1985-1990,4 ofwhich with better resistance,in which the Yudou 2 is most resistant,to this fly were selected after preliminary- and secondar
