Abstract

Sixty four genotypes (39 accessions and 25 advanced breeding lines) of groundnut (Arachis
hypogaea L.) were evaluated for 14 quantitative characters revealed wide range of variability. The
estimates of PCV and GCV were moderate for plant height, matured pods per plant, pod yield per
plant, kernel yield per plant, shelling percentage, 100-kernel weight, harvest index and specific leaf
area. High heritability coupled with high genetic advance was noticed for all the characters under
study except for days to 50% flowering, days to maturity, sound mature kernel per cent and oil
content. In the association analysis, oil yield per plant recorded positive and significant association
with matured pods per plants and kernel yield per plant. Path analysis revealed high direct effects
of kernel yield and oil content. Therefore, it would be rewarding to pay due emphasis on the
selection of these characters for rapid improvement in respect of oil yield
