摘要
用模糊统计分析法分别建立了小麦品种感蚜值、蚜虫在不同品种上的内禀增长率、初羽化无翅雌成蚜胚胎数目、品种对种群的干扰效应值及品种耐害性的隶属函数，将８个小麦品种对禾谷缢管蚜的抗性进行了多目标模糊综合决策．结果表明，８５（６７）２４小麦的综合抗性最强，其次为Ｗ６（４０）２，８５（６７）１５的抗性最差．
The fuzzy subordinate function of the resistant index, such as the infection value of wheat variety to aphid, the intrinsic rate of increase, the embryo number of the adult aphid, the interference effect of variety to aphid and the harm-resistant capacity of variety to aphid etc. , of wheat variety to the aphid were proposed respectively, by applying the fuzzy statistical regression analysis. The fuzzy optimization decision for resistance of wheat varieties to the aphid was made. The result showed that the synthetic resistance of 85 (67)24 is the strongest, w6(40)2.is the next and 85(67)15 is the weakest.
