Genetic variability and heritability studies in Virginia groundnut (Arachis hypogaea L.)
Keywords: Groundnut, genetic variability, heritability, genetic advance
AbstractSixty diverse genotypes of Virginia groundnut were evaluated during kharif 2013 for variability parameters. The estimates of PCV and GCV were high for plant height, number of primary branches per plant, number of mature pods per plant, 100-pod weight, 100-kernel weight, biological yield per plant, kernel yield per plant and harvest index. High heritability coupled with high genetic advance expressed as percentage of mean was observed for 100-pod weight, 100-kernel weight, biological yield per plant and kernel yield per plant indicating that these traits were mainly governed by additive gene action and responsive for further improvement of these traits.
