摘　　要：应用灰色关联度分析法对水稻品种资源抗稻褐飞虱不同生物型和稻瘿蚊中国 型的核心样品进行综合评价。研究结果表明,在抗稻褐飞虱生物型 、中抗稻褐飞虱生物型 、抗稻褐飞虱孟加拉型、抗稻瘿蚊中国 型的核心样品中,分别以IR29692-99-3-2-1、IR36、RP1579-1862-72-31-52、DUOKANGNo.1与标准品种(粤香占)的关联度最大,在抗虫育种亲本选择时,可以作为首选抗源。In the present paper, core collection of rice germplasms which are resistant to different biotypes of rice brown planthopper(BPH) and rice gall midge(GM) were generally evaluated by means of the grey correlative degree.The results indicated that correlative degree of IR29692-99-3-2-1,IR36,RP1579-1862-72-31-52,DUO KANG No.1 with standard variety (Yuexiangzhan) was the biggest value among core collection which was resistant to BPH biotype Ⅱ,moderately resistant to biotype Ⅱ,resistant to biotype Bangladesh,resistant to rice gall midge China type Ⅳ respectively. Four varieties can be selected firstly in the breeding of resistance to the BPH and GM.
