The present investigation was undertaken to know genetic variability, correlation and path coefficient among yield and its contributing characters in 23 germplasm of red Amaranth collected from different parts of India. The experiment was laid at Pt KLS College of Horticulture and Research Station, Rajnandgaon, Chhattisgarh during 2018-19. The experiment was laid out in randomized complete block design (RCBD) with three replications. High magnitude of genotypic as well as phenotypic coefficient of variations were recorded for traits dry stem, dry plant weight, harvest index, leaf stem ratio and fresh stem weight suggested the substantial improvement on amaranth through selection for these traits. High heritability coupled with high genetic advance was observed for dry stem weight, dry plant weight, leaf stem ratio, fresh stem weight, dry leaf weight, harvest index, leaf area, plant fresh weight, fresh leaf weight indicating that most likely the heritability is due to additive gene effects and selection may be effective. The correlation coefficient analysis revealed that number of leaves per plant and fresh stem weight exhibited the significant positive correlation with leaf yield. Hence, direct selection for these traits may lead to the development of high yielding genotypes of amaranth. The path coefficient analysis revealed that the fresh stem weight, dry leaf weight, petiole length, leaf length, leaf stem ratio, dry stem weight, plant fresh weight, plant height and stem base diameter should be considered in selection criteria for increasing leaf yield.
