Ninety genotypes along with three check varieties viz., JL TG37A, PM-2 and UG-5 were evaluated for association analysis at Instructional Farm, College of Technology and Engineering, MPUAT, Udaipur, Rajasthan, India during kharif 2014-15 in Augmented Design. Association estimates revealed that dry pod yield per plant showed positive and significant correlation at both genotypic and phenotypic levels with kernel yield per plant, 100-kernel weight, sound mature kernels and biological yield per plant. Correlation for dry pod yield per plant was divided into direct and indirect effects of different characters. Highest positive direct effect on dry pod yield was exhibited by kernel yield per plant (2.28) followed by days to maturity (0.57), oil content (0.31) and days to 50% flowering (0.22). This indicates that increase in kernel yield per plant, 100-kernel weight and sound mature kernels would improve the dry pod yield per plant of groundnut
