A viral disease was identified on summer squash (Cucurbita pepo L.) plants in the hill state of Himachal Pradesh located in the North Western Himalayan regions, showing symptoms like mosaic, yellowing, shoe stringing of leaves and stunting of plants and infection at early stage of crop could cause as much as 94 per cent reduction of marketable fruits of summer squash. In the present study the causal virus was identified and characterized on the basis of ELISA, RT-PCR and Phylogeny. Partial CP gene was amplified and sequenced. For phylogenetic studies 67 nucleotide and 67 polyprotein sequences of ZYMV belonging to different countries were retrieved from NCBI. Phylogenetic analysis based on nucleotide and protein sequences of each country using Maximum Likelihood (ML), Neighbor Joining (NJ), Maximum Parsimony (MP) and Unweighted Pair Group Method of Arithmetic Averages (UPGMA) methods were achieved via phylip 3.68 and EXOMETM HORIZON, which revealed 91% similarity of the test virus nucleotide sequence with USA ZYMV CP sequence (D13914) and 75.9% similarity with partial polyprotein sequence of Japan (BAE75935).
