Divergence analysis among fifty seven groundnut was carried out using Mahalanobis's D2 statistic. The genotypes were grouped into seven clusters. The association between genetic and geographic diversity cannot be generalized. Maximum divergence was observed between clusters II and VII followed by clusters VI and VII. Days to first flowering followed by shelling percentage contributed maximum to the total divergence. The genotypes VRI 2 (cluster II) for shelling percentage and oil content ICG 3063 (cluster VI) for SMK number and pods and ICG 3254 (cluster VII) for maturity-index and reproductive efficiency were found as potential parents based on cluster mean and genetic diversity.
