Study of Genetic Association and Direct and Indirect Effects among Yield and Yield Contributing Traits in Chickpea

Nibadita Sarker, Md Abdus Samad and Anil Chandra Deb

Eight chickpea varieties were evaluated to determine the relationship among yield and its components using correlation and path-coefficient analysis. Correlation studies revealed that seed weight per plant expressed positive significant correlation with number of primary branches at maximum flower, number of secondary branches at maximum flower, number of pods per plant, pod weight per plant and number of seeds per plant at genotypic level. In phenotypic level, seed yield showed positive significant correlation with number of pods per plant, pod weight per plant and number of seeds per plant. Path-coefficient analysis expressed that the highest positive direct effect was observed for number of seeds per plant followed by pod weight per plant and 1000-seed weight at genotypic level and at phenotypic level number of seeds per plant followed by 1000-seed weight and number of secondary branches per plant on seed yield. These traits could be used for the improvement of seed yield.
