The extent amenable genetic variability and association of important agronomic characters were
determined in set of 50 Groundnut genotypes. Analysis of variance revealed the existence of significant
differences among genotypes for all characters studied. The magnitude of PCV and GCV was moderate to
high for number of pods per plant and plant height, kernel yield, dry pod yield, hundred kernel weight,
and dry haulm yield. High heritability coupled with high genetic advance as per cent of mean was
observed for hundred kernel weight, Dry pod yield, kernel yield, plant height and number of pods per
plant indicating the role of additive gene in expressing these traits. Dry pod yield was significant
positively correlated with kernel yield, number of pods per plant, hundred kernel weight and dry haulm
yield. Path coefficient analysis indicated that number of pods per plant and hundred kernel weight was
important traits to be considered for realizing the improvement in yield.
