Abstract: Ground nut is an important oil seed crop and third largest oilseed crop produced in the world and second largest in India. There is huge gap between world and national average in terms of productivity. TMV-2 being a popular variety was crossed to three improved variety to get the variants with higher yield and qualities of TMV-2. F₂ populations of three crosses viz., TMV-2 × ICGV-91114, TMV-2 × TG-69 and TMV-2 × ICGV-00350 were assessed to estimate the nature and direction of association of pod yield attributes with pod yield in groundnut during kharif -2017 at ARS, Chintamani. All the three crosses showed significant and positive correlation between branches plant^-1 and pods plant^-1 with pod yield plant^-1 where as plant height had significant and negative correlation with pod yield plant^-1 and exerted high direct effect on pod yield plant^-1. This suggests that pods plant^-1, branches plant^-1 and plant height would serve as surrogate traits or as an indirect selection criterion for selecting desirable genotypes in the early segregating generations of groundnut. Shelling percent and sound mature kernel percent had significant and positive correlation with pod yield and kernel yield plant^-1 however, no significant association was observed between days to first flowering and all other traits in F₂ generation of all the three crosses.
