Twenty-four genotypes of groundnut (Arachis hypogaea L.) were evaluated for genetic parameters and character inter-relationship. Phenotypic coefficient of variation was higher than genotypic coefficient of variation for all the traits, the differences were narrow for days to maturity, oil content, protein content, shelling percentage and total pods per plant. High heritability for the first three characters suggested selection response on the phenotypic expression. Pod yield had significant positive association with total pods per plant, matured pods per plant, shelling percentage, 100-pod and kernel weight. Whereas protein content and days to maturity had negative correlation with yield. The direct and indirect effects obtained from path analysis revealed that pod yield was positively associated with total pods per plant, 100-kernel weight, 100-pod weight and shelling percentage would be effective in improving the pod yield in groundnut.
