Abstract:

Cowpea, [Vigna unguiculata (L.) Walp.] also known as blackeye pea, southern pea and lobia is one of the most important food legumes in the semi-arid tropics. With an average of 25% protein (on dry weight basis) in its seeds and tender leaves, cowpea is a major source of protein. In storage, Callosobruchus maculatus F. also called cowpea beetle, cowpea weevil or bruchid, is regarded as the most important and common pest of cowpea both in Africa and Asia. All vigna crops except rice bean are susceptible to bruchids. So in the present study genetics correlation on some of the different susceptibility indices for bruchid resistance in discussed. The indices like infestation per cent is positively correlated with moisture content, actual weight loss, number of bruchids emerged and per cent damage but negatively correlated with yield. Even moisture content, actual weight loss, number of bruchids emerged and per cent damage is negatively correlated with yield. The cowpea seeds permitting lower moisture content and least number of bruchids emerged will lead to lower per cent seed damage and lesser weight loss.
