Abstract: In the present investigation, estimates of genetic variability, heritability and genetic advance were assessed for eight different characters in the F2 population derived from six groundnut crosses viz., JL-24 x GJG-22 (Cross-1), ICGV-05155 x R-33-1 (Cross-2), AK-343 x TPG-41 (Cross-3), JL-501 x TG-36 (Cross-4), TG-26 x GG-20 (Cross-5), JL-1085 x TPG-41 (Cross-6). The mean sums of squares due to genotypes, parents as well as F2s were highly significant for all the characters indicating thereby sufficient variability in the materials studied. The estimates of GCV and PCV were found moderate to high in magnitude in most of the crosses for all the characters except in days to appearance of first flower and days to maturity. High heritability along with high genetic advance and high value of GCV and PCV for pod yield per plant in Cross 1 and Cross 6. Thus, it can be concluded that Cross 1 and Cross 6 for pod yield per plant was mainly under the influence of additive gene actions and selection would be effective for improving these traits.
