Mild mosaic, chlorosis, and distortion symptoms were observed on leaves of Vinca minor in Somerset, NJ. A virus was isolated from these plants and identified as cucumber mosaic virus (CMV) based on host reactions, aphid transmissibility in a nonpersistent manner, icosahedral particle morphology, molecular weight of 29,000 Da of coat protein subunits, and serological relationships. This isolate is designated CMV-Vi. Mouse ascites fluid produced to CMV-Vi gave specific and sensitive reactions in ELISA and Ouchterlony gel double-diffusion tests. Field surveys indicated that CMV is present throughout New Jersey in V. minor.
