6 cowpea cultivars, Pusa Dofasli, Pusa Barsati, L-1552, Brown Seeded and Red Seeded were field evaluated at Ludhiana, India, during the spring and rainy seasons of 1986-1987, for their multiple resistance to bacterial blight, cowpea mosaic virus and anthracnose. Their performance with respect to economic characters such as plant height, days to 50 % flowering, pod length, pod weight and pod yield were also investigated. The relationship between diseases and that between disease and yield were found to differ with season. The mean multiple resistance score for the 2 seasons indicated that Sel-263 ranked as best, followed by Pusa Dofasli, Red Seeded, Pusa Barsati, L-1552,and Brown Seeded cultivars. Sel-263 was the earliest maturing variety and produced the highest pod weight and pod yield. The cultivar Sel-263 can be utilized in further cowpea improvement programmes
