The genetic divergence was studied in the output of twenty phenotypically superior trees in Uttar Pradesh's natural distribution region. Based on morphological and biomass qualities, twenty predominant tree descendants were assembled into eight clusters dependent on the relative of D2 esteems. Cluster I had the most superior tree progenies, with six in all. Cluster II had the greatest intra-cluster gap (3.171), indicating that its progenies were more complex than those of the other clusters. Between clusters I and III, the maximum inter D2 value was obtained (18.275). This current examination's clustering design showed that predominant tree children from different geographic areas were grouped together in a bunch, and the other way around, suggesting that geographic variety doesn't generally infer hereditary variety. The contribution of various traits to diversity showed that seedling height had the greatest impact on separation. The assessment moreover showed that the phenotypic coefficient of variation (PCV) was higher than the comparing genotypic coefficient of variation (GCV) for all the morphological and biomass ascribes which uncovered that the attributes were unpretentious to characteristic changes. The characteristics with low hereditary addition and high heritability demonstrate that the articulation is conceivably constrained by Intra and Inter allelic associations. The hybridization between the more varying genotype of Acacia nilotica can make genotypes with high heterotic vigour.
