ABSTRACT
Thirty genotypes of cowpea (Vigna unguiculata L.) exhibited high genotypic co-efficient of
variation than phenotypic co-efficient of variation for all the characters. Maximum phenotypic and
genotypic co-efficient of variation was recorded by seed yield per plant followed by pods per plant
and clusters per plant. High heritability was recorded by seed yield per plant followed by seeds per
pod, pod length and hundred seed weight. Genetic advance as per cent of mean was higher for seed yield per plant followed by pods per plant and clusters per plant. Seed yield had positive and
significant association with pod length.
