A comparative analysis of economically valuable traits of the early-maturing soybean (Glycine max L.) exotic cultivars (K-126, K-127, and K-183) with the local standard cultivar Orzu was the aim of this study. The analysis centered on assessing the soybean genotypes’ adaptability to the soil and climatic conditions of the Tashkent Region, Uzbekistan. The examined key indicators included grain yield, 1000-seed weight, and protein, oil, and cellulose contents. Analysis of variance revealed significant differences among the soybean cultivars, identifying promising directions for breeding. The standard cultivar Orzu demonstrated the highest yield and protein content. The exotic cultivar K-126 stood out for its high oil content, suggesting its potential for vegetable oil production. The exotic cultivar K-183 showed the maximum cellulose content, beneficial for use in the biomaterial and bioenergy production. The results identified the promising soybean genotypes for targeted breeding focused on food, oil production, and industrial bioresource applications.
