An evaluation of the main cultivated Medicago sativa cultivars (strains) for Acyrthosiphon pisum resistance in Ningxia
摘要
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 popula-tion in the field was complex,consisting mainly of Acyrthosiphon pisum (over 80% of the total aphid popula-tion).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 re-sistant variety,with an aphid ration of 0.51.Santory,Crown,Queen,SR4030 and MF4020 were resistant va-rieties,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.关键词
