Abstract
A mild str. of groundnut mottle virus was found in cowpea fields in Ga. in 1980 and 1981 but only when groundnut fields were near. Infected cowpeas were either symptomless or showed a mild mottle, and growth and yield were not affected in greenhouse studies. Of 24 Vigna entries tested 10 were resistant. Aphis craccivora transmitted GMV to and from cowpea and from cowpea to groundnut. A low frequency of seed transmission was detected in 1 cowpea introduction and field tests demonstrated natural transmission between cowpeas and/or groundnuts. The necrosis str. of GMV caused a more severe disease in cowpea than the mild str. and mixed infection of GMV and cucumber mosaic virus caused a synergistic disease reaction in cowpea.
