Abstract

Diallel analysis conducted in six genotypes of cowpea revealed that additive gene action for the expression of days to flowering, number of leaves, leaf area index, specific leaf weight, green fodder yield, dry matter yield and leaf:stem ratio and non-additive gene action for plant height, number of branches and crude protein content. Among the parents, UPC 9202, UPC 9103 and CO S were found to be the best combiners. The crosses UPC 9202 x CO 5 and UPC 9103 x CO 5 were found to be the best specific combiners for green fodder and dry matter yield.

Keywords: Cowpea, Fodder yield, Additive Gene Action
