Abstract
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.
