Soybean (Glycine max (L.) Merr.) is one of the important oilseed crops that is widely cultivated around the world. It has a high amount of protein content as well as other essential vitamins that are important in our daily lives. For continuous improvement, the development of novel plant species that are resistant to biotic and abiotic stress using effective genetic diversity strategies is important. In the current study, a total of 25 diverse genotypes of soybean using 21 important agro morphological traits were studied. For qualitative traits significant level of variation was found for most of the traits. For quantitative traits, the highest coefficient of variance 32.74% was found for days to flower initiation, followed by days to flower completion 29.62%, while the lowest was found for a number of pods/plants 2.96%. Based on cluster analysis, all the genotypes were separated into two groups at 25% distance and further subdivided at 75% distance, where the genotypes NARC-2 and SWAT-84 were found the most diverse. The cluster three genotypes were found to have early mature genotypes (89 ± 2.44). Based on a number of pods/plant and yield per plant, the cluster 4 genotypes were found to have a maximum number of pods/plant (98.26 ± 32.10), and (38.66 ± 6.85). Among the studied genotypes the highest grain yield (49 g) was produced by genotype C/B 28, whereas the lowest (14.56 g) was observed for C/B 7. Principal component analysis with an eigenvalue of 1.48 accounted for the total variation of 67.73%. The total seed storage proteins analysis resulted in 13 bands, and the molecular weight ranged from 15 to 170 kDa. Two-way cluster analysis was performed and all the populations were divided into two main lineages at 25% distance and further sub divided into six subgroups at distance of a 75%, where the genotypes NARC-2 and SWAT-84 were found the most diverse genotypes. These findings provide a basis for developing elite, locally adapted soybean genotypes as well as implications for understanding the diversity and relationships among these diverse Glycine max genotypes.
