In this study, laboratory bioassays were carried out for rapid initial evaluation on the resistance of 10 grape rootstocks and 18 cultivars to Chinese biotypes of grape phylloxera, Daktulosphaira viticola. The survival ratio, developmental duration, egg number and index for population age constitution were evaluated.

为了检测我国葡萄品种和砧木对中国生态型葡萄根瘤蚜Daktulosphaira viticola的抗性，在实验室条件下采用离体根接种法鉴定了10个葡萄砧木、18个葡萄栽培品种，测定了根瘤蚜存活率、发育历期、产卵量、种群龄期结构指数和成虫大小等指标。

Results showed that the rootstocks RSB, Gravesac, 520A and 225R were immune to phylloxera infestation. Fercal, 1613C and the HPDs was resistant to phylloxera to some extent, whose tuberosities % were less than 27%. The Both Henan wild grapes and V. adenocluda were highly sensitive to phylloxera,whose tuberosities were 66.25% and 56.67% and phylloxera produced 181.67 and 277.67 eggs on each of them; V.guangxi-quinquangularis had low resistance, whose tuberosities were 15.45%, its hybrid with a V.vinifera variety NW196 was sensible to phylloxera, whose tuberosities and egg number phylloxera produced were 46.13% and 55.28% higher than V. guangxi-quinquangularis.

结果表明：砧木RSB、Gravesac、520A和225R对根瘤蚜免疫，砧木Fercal、1613C和供试的种间杂种对根瘤蚜有一定抗性，根瘤比例均低于27%；河南野葡萄和腺枝葡萄对根瘤蚜敏感，根瘤比例分别为66.25%和56.67%，总产卵量分别达到181.67粒和277.67粒，广西毛葡萄对根瘤蚜有一定抗性，根瘤比例为15.45%，其与粉红玫瑰的杂交后代NW196抗性下降，产卵量与根瘤比例分别比广西毛葡萄高46.13%和55.28%。
