Genotypic and phenotypic coefficients of variation were highest for seed yield per plant followed by 100 seed weight and zinc content. The character days to maturity recorded lowest genotypic coefficient of variation. The maximum phenotypic coefficient of variation was recorded for seed yield per plant and 100 seed weight. High heritability coupled with high genetic advance as percent of mean was observed for all characters except days to 50% flowering, days to maturity, number of seeds per plant and 100 seed weight indicating that these traits were predominantly governed by additive gene action and suggesting that selection in these traits would be effectively made desired genetic improvement.

The significant positive correlation was observed between seed yield per plant with number of pods per plant, number of primary branches per plant, number of secondary branches per plant, number of pods per plant, 100 seed weight and iron content at both genotypic and phenotypic level. While seed yield per plant exhibited negative and non significant correlation with the characters days to maturity and wilt% at both genotypic and phenotypic level. Other characters showed negligible amount of positive and non significant correlation with days to maturity, plant height and zinc content at both genotypic and phenotypic levels.
