This study evaluated the performance cowpea genotypes in the field in Ibadan, Nigeria for response to infection induced by four seed transmitted viruses of cowpea. The experiment was laid out in split plot design with
three replicates. Cowpea mottle virus genus Carmovirus (CMeV) produced infection in 14 of the 15 lines, Bean common mosaic virus genus Potyvirus - blackeye cowpea strain (BCMV – BlC) in 12, Cowpea aphid-borne mosaic
virus genus Potyvirus (CABMV) in 11 and Southern bean mosaic virus genus Sobemovirus (SBMV) in 6. BCMV – BlC significantly reduced (p
