The present experiment was conducted with 15 groundnut genotypes to estimate the genetic variability and correlation for yiel d and its components. Analysis of variance clearly specified the existence of ample amount of variability in present experimental material for improvement. Variability studies indicated the higher scope of selection in desirable direction for number of pods per plant, shelling percentage, hundred kernel weight, hundred pod weight, dry pod yield per hectare and kernel

These traits were found to be governed by additive genes as evident by recording higher values for both heritability and genetic advance. Correlation studies revealed the simultaneous improvement of hundred pod weight, sound mature kernels and hundred kernel weights for improvement of the yield.
