Correlation and path co-efficient analysis were carried out for pod yield and some of its component characters in 50 Virginia runner genotypes of groundnut. The genotypic correlation co-efficients were observed to be relatively of higher magnitude than the corresponding phenotypic and environmental correlation co-efficient, indicating strong inherent association, between the character. Pod yield possessed significant positive association with harvest index, shelling percentage, number of mature pods per plant, 100-seed weight and number of primary branches per plant at both the genotypic and phenotypic levels. Path analysis also revealed the importance of these traits as they had affected pod yield directly. Therefore, selection based on these characters will lead to rapid improvement in pod yield.
