Bean Common Mosaic Virus (BCMV) is an important viral disease in legumes, particularly the cowpea. It is a member of potyvirus, transmitted mechanically and by aphids in a non- persistent manner. Seed transmission results in the primary dispersal of the virus to new locations, often difficult to contain the spread of the virus. Hence seed transmission studies were carried out in cowpea variety C-152. It was determined by the grow out test at the two-leaf stage. The rate of seed transmission varied from 20-30 per cent in pot culture studies. Seed-borne nature of BCMV in cowpea was confirmed by DAS ELISA. Serological DAS ELISA of the cowpea seeds harvested from BCMV infected plants of both cultivars C-152 and KBC-2 revealed the presence of BCMV in embryo and cotyledon, but not in the seed coat. However, the virus titre differed between cotyledon and embryo between both the cultivars.
