Understanding the relationship between seed size and oil content is the most important goals in groundnut (Arachis hypogaea) breeding programs for the selection of desirable traits in the breeding for confectionery and oil types. In the present study, the inter-relationship between oil content and its component traits were studied using 64 groundnut genotypes. Observations were recorded for 11 pod and kernel traits viz., 100-pod weight (g), pod length (mm), pod width (mm), 100-kernel weight (g), kernel length (mm), kernel width (mm), shell weight (g), shell thickness (mm), shelling %, days to maturity and oil content (%). Character association analysis revealed that 100-pod weight recorded positive and significant association with 100-kernel weight. In turn, these two traits 100-pod weight and 100-kernel weight have shown a negative correlation with oil content suggesting that seed mass has an inverse relationship with oil content. So it can be concluded that pod and seed size are correlated with oil content. Hence bold and small pod or seed nature can be considered as selection indices for low and high oil types respectively. In addition, both 100-pod weight and 100-kernel weight have recorded significant and positive association with pod length, pod width, kernel length, kernel width and shell weight. Hence these traits may also be given due emphasis as selection criteria for the development of high or low oil content genotypes.
