Abstract

The experiment material comprised of 150 mutant lines including two checks viz., RC-19 and RC-101 of cowpea to study genetic parameters for eleven characters. The estimates of PCV were found to be higher than estimates of GCV for all eleven characters it showing that the apparent variation is not only due to genotypes but also due to the influence of the environment. Higher GCV and PCV were observed for number of primary branches per plant and seed yield per plant. The estimates of heritability were observed to be higher for all the characters. Genetic advance as percentage of mean was higher observed for the number of primary branches per plant, seed yield per plant, number of seeds per pod, number of pods per plant, pod length, harvest index and biological yield per plant.
