Genetic improvement of cowpea, vigna unguiculata (L) walp seed yield

The heritability and inter-correlation study of Cowpea grown for seed purpose is reported. All characters examined were found to have high heritability. Selection index technique was found to be not efficient over straight selection. An ideal plant which gives higher seed yield should preferably flower early, have longer peduncles, have more peduncles and have more number of seeds per pod.
