virus associated with severe mosaic disease of gherkin ( Cucumis anguria L.) in south India was identified. The infected plants showed mosaic, vein banding, blistering on malformed leaves and fruits. Host range, transmission, serological and electron microscopic studies were carried out to identify the virus. The virus was readily transmitted by Sap inoculation and by aphids in a non-persistent manner. The host range of the virus was mainly limited to cucurbitaceous and chenopodium species. The virus showed positive serological relationships with members of potyvirus genus but not with cucumo, ilar and taspoviruses. Electron microscopy of leaf dip preparation of infected leaves revealed long flexuous filamentous virus particles measuring 750 × 12 nm. On the basis of symptomotology, host range, transmission, serology and particle morphology the virus associated with mosaic disease of gherkin might be the member of potyvirus genus.
