Abstract: The resistance of 20 Vitis vin ifera varieties, 18 V. vinifera2V. labrusca varieties, 11 hybrides producteurs directs (HPD) , 6 grape rootstocks, 3 wild grapes and 1 hybrid of wild grape and V. vinifera to grape phylloxera (Daktulosphaira vitifoliae Fitch ) were evaluated. The survival ratio, number of eggs,phylloxera and the tuberosity were evaluated. Results showed that the rootstocks RSB, Gravesac, 520A and 225R were immune to phylloxera infestation. Fercal, 1613C and the HPDswere resistant to phylloxera to some extent, whose tuberosities persent were less than 27%. Both Henan wild grape 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. quinquangu laris 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. quinquangularis. It was concluded that grape of different varieties had different resistance to phylloxera, the resistance level not only depended on their parents but also depended on the proportion of each parents.
