The present experiment was conducted to study the genetic parameters viz., variability, heritability and genetic advance of thirty genotypes of groundnut during kharif, 2017 under organic fertilizer management. Analysis of variance revealed that there is an ample amount of variation among the genotypes. Among the 22 characters studied, number of immature pods per plant, kernel yield per plant, pod yield per plant and total free amino acid content recorded higher estimates of GCV and PCV. The characters total free amino acids, carbohydrate content, SLA at 60 DAS and hundred kernel weight reported high heritability coupled with high genetic advance as percent of mean indicating the influence of additive gene action and hence selection for these traits would be very effective under organic fertilizer management.
