Estimationof genetic diversity and identification of groundnut cultivars was conducted with 25 genotypes (including National and State released varieties) The observations were recorded for 13 charactersviz., days to 50% flowering, days to maturity, plant height, number of branches per plant, number of matured pods per plant, dry pod yield per plant, kernel yield per plant, 100-kernel weight, sound mature kernel, shelling out turn, biological yield per plant, harvest index and seed oil content. The, estimates of genotypic parameters revealed that differences between the estimates of GCV and PCV werefound least for most of the characters. Higher estimates of GCV were observed for plant height (14.94), number of mature pods per plant, dry pods yield per plant (21.86), Kernel yield per plant (19.50), Biological yield per plant (24.88), 100 Kernel weight (14.50) and oil content (18.62). Maximum heritability was found for 100 kernel weight (99.58) followed by oil content (98.98) and sound mature kernels (98.75). While, maximum genetic gain was observed for biological yield per plant (50.78) followed by dry pods yield per plant (44.75) and number of mature pods per plant (42.83). Such information regarding genetic variation may be used for more effective breeding programmes.
