摘　　要：为发掘抗蚜虫种质,对32份切花菊进行了人工蚜虫接种,统计了蚜虫接种后不同品种上虫口数量和蚜量比值。结果表明:不同品种对蚜虫的抗性表现出明显差异,蚜虫接种21d时各品种上虫口数量差异甚大,为0～267头不等;根据蚜量比值可将菊花抗蚜虫性分为5级,分别为:高抗,0～0.25;中抗,0.26～0.50;抗,0.51～0.75;低抗,0.76～1.25;不抗,>1.25。32份切花菊中,有14个菊花品种为不抗品种;4个品种为低抗品种;3个品种为抗虫品种;1个品种为中抗品种;10个品种为高抗品种。In order to discover aphid-resistant germplasm,32 cut chrysanthemum （Chrysanthemum grandiflorum） cultivars were artificially inoculated with aphids,and the aphid number and its ratio on the cultivars were investigated.Different chrysanthemum cultivars had different levels of aphid-resistance.After 21 days inoculation,the aphid number varied with cultivars,ranging from 0 to 267.The aphid-resistance of chrysanthemum could be divided into five grades in terms of aphid number ratio,i.e.,high resistance （aphid number ratio 0-0.25）,moderate resistance （0.26-0.50）,resistance （0.51-0.75）,low resistance （0.76-1.25）,and non-resistance （1.25）.Among 32 test cultivars,14 cultivars were of non-resistance,4 cultivars were of low resistance,3 cultivars were of resistance,1 cultivar was of moderate resistance,and 10 cultivars were of high resistance.
