Twenty-six genotypes of groundnut were evaluated for estimation of genetic parameters and character inter-relationship among the yield contributing characters. These genotypes showed noticeable differences in days to maturity, test weight, sound mature kernels, harvest index, protein content, and pod yield per plant. Test weight reported the highest value for the phenotypic coefficient of variations (PCV), genotypic coefficient of variations (GCV), genetic advance (GA), and percentage genetic advance while protein content testified as the best heritable trait. During correlation analysis, days to maturity, test weight, harvest index, and protein content indicated positive relation with pod yield for genotypic (rg) and phenotypic (rp) correlation coefficient. Harvest index, days to 50% flowering, protein content and test weight showed direct positive effect on pod yield per plant.
