The results indicated that their resistance abilities are as follows: Aigeros > Aigeros×Aigeros > Aigeros×Tacamabaca > Tacamabaca. Disease resistant varieties are Populus deltoids and P. deltoides×P. trichcarpa are immune, P. deltoides×P.deltoids, P. deltoides and P. nigra and high sensitive varieties are P.cathayana, P. deltoides×P. trichcarpa, P. deltoides×P. nigra, P. deltoides×P. deltoides, P. deltoides×P. nigra, P. deltoides×P.simonii and P. deltoides.
