Assessment of correlation and path analysis in collection’s genotypes of chickpea

Abstract

Twenty three collection genotypes of chickpea were evaluated for 10 components of yield (3 phenological and 7 plant data) on grain yield per plant. Investigation was carried out on field of Institution in 2022-2023. Correlation analysis revealed significant relationship by characters: days taken to flowering and maturity, primary and secondary branches per plant and 100 grain weight with grain yield. Highly negative correlation with yield had component grain per pod. Path analysis revealed direct effect on yield following components: highest effect had character 100 grain weight (0.833) followed by pods per plant (0.562), days to flowering (0.362), primary branches per plant (0.192) and secondary branches per plant (0.074). Highest negative direct effect on yield had character grain per pod (-0.881) followed by grain per plant (-0.593), days taken to maturity (-0.106). Grain per plant was formed mainly on basis 6 components by indirect effects.
