Genetic Variability Studies in Cowpea (Vigna Unguiculata L. Walp)

Abstract

Genetic variability, heritability, genetic advance and genetic advance as per cent of mean for twelve characters were assessed by field evaluation of twenty two genotypes at the college of horticulture, Vellanikkara. The high degree of variability was observed for all the characters. High magnitude of the phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic advance was observed for plant height, grain yield per plant and length of the pods. Seeds per pod and protein content exhibited low PCV and GCV, but high irritability and low genetic gain. The difference between the phenotype coefficient of variation and genotype coefficient of variation were found maximum in pod weight (30.15%), followed by number of pods per plant (18.12%) and test weight (16.27%).
