Results obtained could be summarized as follows: I. Identification of the virus: The virus isolated was identified according to host range symptomatology: Physical properties, modes of transmission, electron microscopy and ELISA. Thirty nine host plants belonging to seven plant families were found to be susceptible to infection with CMV studied strain.
