摘要: 运用蚜量比值法和模糊识别法,对12个宁夏主栽苜蓿品种(系)进行了田间和室内抗蚜评价试验。田间蚜虫种类以豌豆蚜(Acyrthosiphon pisum)为主,占混合种群数量的80%以上。田间和室内结果综合分析表明:供试12个苜蓿品种(品系)中,惊喜、WL343HQ和德宝3个品种为高感品种,其蚜量比值均大于1.25,并与其他品种间差异极显著;柏拉图、中苜3号、甘农4号等3个品种为感蚜品种,其蚜量比值位于0.76~1.25之间;先行者为中抗品种,蚜量比值为0.51,位于0.51~0.75之间;皇冠、三得利、皇后、SR4030和MF40205等5个品种为抗蚜品种,其蚜量比值 0.26~0.50之间。同时,本研究也提出了室内和田间苜蓿抗蚜鉴定方法分别为模糊识别法和蚜量比值法的评价方法和标准。

Abstract: An evaluation of the 12 main Medicago sativa cultivars (strains) for aphid resistance was carried out using aphid ration and fuzzy recognition methods in field and indoor conditions in Ningxia. The aphid population in the field was complex, consisting mainly of Acyrthosiphon pisum (over 80% of the total aphid population). Field and indoor analysis showed that Surprising, WL343HQ and Derby were high susceptible strains, with aphid rations above 1.25 and significantly higher than the other cultivars. Platon, Zhongmu No.3 and Gannong No.4 were susceptible varieties, with aphid rations between 0.76 and 1.25. Pioneer was a middle resistant variety, with an aphid ration of 0.51. Santory, Crown, Queen, SR4030 and MF4020 were resistant varieties, with aphid rations between 0.26 and 0.50. Based on this study, a standard damage index of aphids to Medicago, and aphid ration and fuzzy recognition methods, are recommended for evaluating aphid resistance in field and indoor situations.
