First report of Papaya ringspot virus– W in bottle gourd ( Lagenaria siceraria) from India.

This article presents the first reported case of papaya ringspot virus in bottle gourd (Lagenaria siceraria) from India. The virus isolate produced characteristic symptoms of mosaic, mottling, interveinal chlorotic bands, leaf distortion, malformation of fruits and reduction in fruit size. The enzyme-linked immunosorbent assay testing using 16 antisera from five distinct virus groups (poty-, cucumo-, tobomo-, tospo- and ilarviruses) revealed that the virus isolate reacted strongly to Papaya ringspot virus (P and W strains), in addition to weaker reactions with three other potyvirus antisera: Tobacco etch virus, Chilli veinal mottle virus and Potato virus Y.
