This study explores the genetic diversity of soybean (Glycine max) genotypes using polyacrylamide gel electrophoresis (A-PAGE) to analyze globulin reserve proteins. The research utilized 51 soybean genotypes from various origins, including Canada, Turkey, Uzbekistan and others. The A-PAGE method was employed to extract and analyze the globulin storage proteins in the grains of soybean samples. The proteins were categorized into ω, γ, β and α zones, revealing distinct electrophoretic patterns among the genotypes. A total of 22 spectra and 107 patterns were identified, demonstrating polymorphism based on the frequency of occurrence. The genetic diversity index, calculated using Nei’s formula, indicated varying levels of genetic diversity across the different zones.
