In the present investigation, estimates of genetic variability, heritability and genetic advance were assessed for nine different characters in the F3 population derived from four groundnut crosses, viz., CO 7 × VRI Gn 6, TMV 2 × VRI Gn 6, TMV Gn 13 × VRI Gn 6 and VRI 2 × VRI Gn 6. Considering the mean performance, the cross derivative TMV Gn 13 × VRI Gn 6 registered superiority for the characters viz., 100-pod weight (g), 100- kernel weight (g) and sound mature kernel (%). Apart from these characters, the cross VRI 2 × VRI Gn 6 for shelling (%) and sound mature kernel (%), and CO 7 × VRI Gn 6 for the trait late leaf spot and rust score also showed higher mean performance. | Variability studies for quantitative traits in F3 generation of groundnut Arachis hypogaea L.
