Abstract
Twenty eight entries comprising 7 parents and 21 hybrids in F1 and F2 generations of chickpea (C. arietinum L.) were grown in randomized block design for the studies of phenotypic and genotypic correlations and path coefficient analysis. Grain yield was positively associated with the number of pods per plant, number of seeds per pod, pod bearing length and number of secondary branches in both the F1 and F2 generations. The correlation coefficient and path coefficient analyses revealed that number of pods per plant and number of secondary branches were the most stable and important yield contributing traits. The other characters which would be kept in mind for selection, were 100-grain weight, number of seeds per pod and pod bearing length coupled with longer duration of seed development which would provide a better plant type in chickpeas. Selection based on those attributes would increase the efficiency of selection.
