摘　　要：通过对９８个棉花品种的苗期鉴定，筛选出了一批对朱砂叶螨抗性强的种质资源，包括亚洲棉、海岛棉和部分具有多毛、红叶和无色素腺性状的陆地棉品种。所鉴定的红叶、多毛和无色素腺品种平均受害指数显著低于推广品种，表明这些性状具有潜在的抗螨性。多毛品种高的叶毛密度须协同一定的叶毛长度才具有抗螨性。The experiment on screening and identification seedlings of cotton cultivars of higher resistance to the carmine spidermite,Tetranytrus cinnabarinus (Boisduval) was carried out in 1993～1995.The result revealed that Gossypium barbadence,G.arbareum,and some cultivars of G.Hirsutum like higher leaf-hair density,red-leaf and glandless possessed resistance to mites.The average damage index of the dentified cultivars with red-leaf,higher leaf-hair density and glandless was significantly lower than that of the diffused ones,which indicated that these characters possessed potential resistance to mites. Resistant rate in cultivars with higher leaf-hair density related to the length of leaf-hair.
