Abstract
A set of twenty four genotypes of Chickpea including one check, which were grown in the Field to study the amount of genetic variability, association between quantitative traits and seed yield, direct and indirect effect of yield contributing characters on seed yield in chickpea germplasm. High significant variation was obtained for all characters studied. High GCV and PCV in chickpea germplasm were observed higher for number of seeds per plant, number of secondary branches, number of pods per plant, number of seeds per pod, hundred seed weight, biological yield, seed yield. High estimate of heritability coupled with high genetic advance as percent of mean was recorded for number of seeds per plant, seed index, number of pods per plant, harvest index. High values for heritability indicates that it may be due to higher contribution of genotypic components. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively. Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant association with number of pods per plant, number of seeds per plant, biological yield per plant, harvest index at genotypic and phenotypic levels. Path analysis revealed that characters plant height, biological yield, harvest index and hundred seed weight, have positive direct effect on seed yield per plant at genotypic and phenotypic level. The above mentioned traits should be given due emphasis for future genetic improvement of chickpea because they possess high genetic variance, heritability coupled with genetic advance a percent of mean and correlation among themselves which leads to more genetic advance under proper selection in a breeding programme.
