The morphological and cytopathological characters of the viruses were observed by electron microscopy The types of virus were identified with I-ELISA, DAS-ELISA, TAS-ELISA, RT-PCR and IC-PCR. The CP genes of the main viruses identified in this research were amplified by PCR, cloned into pGEM-T and sequenced. The pumpkin germplasm from Heilongjiang and Yunnan provinces was screened for resistance to the main viruses using friction and roots immersed inoculation.
