Sorghum is a popular cereal crop worldwide, and therefore, the understanding and utilization of sorghum accessions play role crucial for improving crop productivity. The in-depth knowledge of genetic variation between the sorghum accessions will allow the plant breeder for precise breeding. Thus, exploration of sorghum crop genetic diversity is inevitable. In this study, we investigated the genetic diversity among the thirty sorghum accessions by using the quantitative morphological traits. The findings were concluded on the basis of ten quantitative traits, among which 07 diverse quantitative traits which maximized the variation, chosen carefully for genetic diversity analysis. We found a significant positive correlation of stalk yield with days to flowering and no. of leaves per plant. Similarly, for grain yield with no. of leaves per plant and panicle width. The PCA revealed that days to flowering, plant height, panicle width, and leaf area contributed maximum towards the divergence. Sorghum accessions were grouped under 4 clusters by using hierarchical analysis. Cluster-2 contained minimum while cluster-4 had maximum number of sorghum accessions. The maximum inter-cluster distance was recorded between cluster-2 and cluster-4. The cluster-4 had the highest mean values for no. of leaves per plant, stalk yield, and days to maturity. Therefore, parent selection must be dependent on best yield related components and wider inter-cluster distance. Therefore, in current study, the quantitative morphological traits showed the broader genetic diversity range among the thirty sorghum accessions, and can be utilized effectively for the improvement of genetic architecture.
