Abstract:
The present research entitled “Genetic variability and character association studies in F3 generation of cowpea. (Vigna unguiculata (L.) Walp.)” was carried out for assessing the genetic variability, heritability, expected genetic advance for yield contributing traits in F3 generation of 45 genotypess of cowpea. The results revealed that estimates of mean sum of squares due to genotypes was highly significant for all the characters studied. In general it was found that magnitude of phenotypic variances were higher than respective genotypic variances for all the characters. Plant height had highest estimate of phenotypic and genotypic variance. High estimates of heritability coupled with genetic advance as per cent of mean was observed for characters plant height at maturity, harvest index, seed yield per plant, number of pods per plant, number of branches per plant, and number of clusters per plants.
