Thirty-eight local collections of groundnut collected from Gadchiroli district along with two checks namely TAG-24 and Kopergaon-3 were evaluated in RBD with three replications. The results on correlation studies showed that dry pod yield plant⁻¹ was significant and positively correlated with number of mature pods plant⁻¹ at both genotypic and phenotypic levels. Whereas, genotypic positive significant correlation of dry pod yield plant⁻¹ was observed with number of primary branches plant⁻¹ and mature kernels per cent. The partitioning of positive genotypic correlation of dry pod yield plant⁻¹ with different traits into direct and indirect effects revealed that days to 50 per cent flowering (1.014) contributed highest positive direct effect to dry pod yield plant⁻¹ followed by hundred kernel weight (0.664), number mature pods plant⁻¹ (0.606), mature kernel per cent (0.395), plant height (0.254), oil content (0.108) and number of immature pods plant⁻¹ (0.001). The major contributors to the indirect effect were number of mature pod plant⁻¹ and mature kernel per cent. These two characters have also contributed maximum direct effect towards dry pod yield plant⁻¹. The correlation and path coefficient analysis revealed importance of number of mature pods plant⁻¹ and mature kernels per cent as the promising characters to increase dry pod yield plant⁻¹ both directly and indirectly.
