AICRP on Groundnut, Agricultural Research Station, Chintamani - 563 125, Chikkaballapur Dist., Karnataka, India.
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.
