This article presents the results of evaluation of soybean source material on the main economically valuable traits for purposeful use in the breeding process. The study of 112 soybean varieties of different ecological and geographical origin was carried out on the basis of the Konstantinov Volga Research Institute of Breeding and Seed Farming in 2019-2021. Most of the collection was represented by samples that belonged to ripeness groups: early ripe (91-100 days) - 57.3%, early to medium ripe (101 - 110 days) -39.1%. The medium-ripening group was represented by 3.6% of samples. As a result of research, the average positive correlation of branching with productivity was determined (r=0.57-0.67). In all years of the study, a strong correlation between the number of beans per plant and productivity of soybean plants was established (r=0.93-0.98). A strong direct correlation between seed weight per plant and seed productivity (r=0.93-0.98) was established. As a result of the study, samples were selected according to a set of traits characterizing processability, high productivity, and increased protein content in seeds. The selected samples with the most valuable properties can be used as source material for the development of new high-yielding soybean varieties for rainfed conditions of the forest-steppe of the Middle Volga region
