Abstract

Thirty chickpea genotypes were studied for seed yield and its components for estimating genetic variability and correlation co-efficient. Analysis of variance for seed yield and its component showed significant differences among the genotypes for all nine traits. Highly significant and positive genotypic association between primary branches/ plant and pods / plant, plant height and days to maturity, days to maturity and pods/ plant, seeds/ pod and days to 50% flowering, days to maturity and seed yield/ plant and similarly 100 seed weight and seed yield/ plant were found.  Highly significant  and negative genotypic correlation between primary branches/ plant and plant height; primary branches/ plant and plant width; primary branches/ plant and days to 50% flowering; primary branches/ plant and days to maturity; plant height and plant width; plant height and pods/ plant; seeds/ pod and 100 seed weight; days to 50% flowering and 100 seed weight were observed. The correlation between 100 seed weight and seed yield showed highest correlation coefficient 0.681**. This 100 seed weight may be an important criterion for  seed yield improvement in chickpea.
