In the present investigation, twenty eight genotypes of grain amaranth (Amaranthus hypochondriacus L.) were evaluated for their genetic divergence at field level using a randomized block design. The analysis of morphological variance exhibited significant differences among the genotypes for all the nine characters indicating the presence of substantial degree of variability. It was observed that the estimates for genotypic coefficients of variation (GCV) were equal to or lowest than the phenotypic coefficient of variation for all the characters. Grain weight (g/10 ml) exhibited the lowest GCV (3.75) while grain yield per plant (g) and grain yield per plot had the highest GCV (29.31) as well as PCV (31.90). The lowest heritability (b.s) was observed for width of inflorescence (53%). The highest heritability (b.s) was exhibited by days to 50% flowering (100%), days to maturity (100%) and grain weight (100%). The characters plant height at maturity (30.82) showed higher genetic advance followed by days to maturity (12.34). Mahalanobis D2 analysis revealed the presence of high amount of genetic diversity among 28 genotypes, which formed five clusters. The cluster I contained maximum i.e. 12 genotypes while in cluster II, there were 8 genotypes. Cluster III having 5 genotypes, Cluster V having 2 genotypes and Cluster IV was monogenotypic.
