摘要: 应用50个小麦品种对麦长管蚜抗性鉴定指标值进行模糊统计回归分析,提出了品种自然感蚜量、蚜虫在品种上的累积存活率、平均发育历期、产仔率、内禀增长率(rm)及品种耐害性等抗性指标的模糊隶属函数,建立了品种抗性的模糊综合决策模型。对10个品种的抗蚜性综合决策结果表明,陕167的综合抗蚜性最强,83(37)65、(87)113、82246次之,小偃6号最差。同时,综合型决策模型的决策结果最优,精度高,保留较多信息。

Abstract: The resistance indexes of 50 wheat varieties to Macrosiphum avenae were applied to carry out the fuzzy statistical regression analysis. The fuzzy subordinate function of such resistance indexes as the quantity of aphid natural infection to wheat varieties, the accumulated rate of aphid survivals, the period of average development, the reproduction rate, the intrinsic increase rate(rm) and the harm-resistance of wheat varieties were set up, and the fuzzy comprehensive decision making models of resistance were established. The result indicates that fuzzy comprehensive decision model Vhad a high precision and much information holding.
