Heritability and relationship of quantitative traits was studied in 36genotypes of chickpea. Analysis of variance showed highly significantdifferences among genotypes for primary branches, secondary branches, plantheight, pods per plant, biological and grain yield. The high heritabilityassociated with high genetic advance was recorded for plant height. Moderateheritability associated with high genetic advance was observed for biologicalyield whereas primary branches, secondary branches and grain yield had lowheritability associated with low genetic advance. Number of pods per plantexhibited low heritability with high genetic advance. Low heritability percoupled with low and moderate genetic advance, observed for primary andsecondary branches respectively, indicated that these traits were greatlyinfluenced by environment. The genotypic association of primary branches withgrain yield was negative. Their phenotypic correlation was however, positiveand non-significant. The genotypic correlation of secondary branches withgrain yield was positive. A positive and non-significant relationship betweenprimary branches and pods per plant was obtained. The relationship betweennumber of pods and biological yield was positive and highly significant; bothof these traits had significant and positive correlation with grain yield. On thebasis of these results it can be suggested that plant height, number of podsper plant and biological yield may be given more importance while makingselection for higher yield potential in chickpea.
