Abstract
Twenty two genotypes of kabuli chickpea were tested to assess variability, heritability, genetic advance, correlation and path analysis between yield and yield components. Among the different yield attributing traits, 100-seed weight had the highest magnitude of genotypic coefficient of variation, whereas-phenotypic coefficient of variation was found to be high for 100-seed weight followed by seed yield per plant and secondary branches per plant. High heritability coupled with high genetic advance was recorded for 100-seed weight. The correlation analysis revealed that seed yield per plant exhibited a significant positive association with primary branches per plant, secondary branches per plant, pods per plant, biological yield per plant and harvest index; and significant negative correlation with days to maturity at genotypic level. Path coefficient analysis for seed yield and its components showed that direct selection for biological yield per plant, harvest index, pods per plant and secondary branches per plant would likely to be effective in increasing seed yield in kabuli chickpea.
