In order to provide the basis for breeding physiology-resistant rootstocks,laboratory bioassays were carried out for evaluation on the progenies' resistance and inheritance of 6 cross combinations.The result showed that SO4,5BB,1103 P,Vitis riparia 580,V.yanshanensis 0947 and V.champini 1148 were resistant to phylloxera,.Beta and V.amurensis were susceptible to phylloxera.The resistance to phylloxera of 6 cross progenies showed the traits of continuous distribution and quantitative inheritance.In process of...
