Abstract:
Genetic variability studies in thirty one genotypes of vegetable cowpea revealed significant
difference for all the characters except primary branches. A wide range of phenotypic coefficient of
. variation (7.4 to 56.7) was observed. High genotypic coefficient of variation was observed for pod
weight (54.6) and pod yield per plant (53.1). All the characters exhibited high heritability (78% to
97%). Heritability and genetic advance were high for pod weight and yield per plant, which can be
relied up on for the effective genetic improvement of cowpea.
