The goal of the work was to obtain antibiotic-resistant forms of endophytic Glycine max L. (Merill) bacteria and to study their introduction potential affected by different seed treatment methods. Rifampicin-resistant variants of endophytic soybean bacteria Rhizobium radiobacter 27c and Pseudomonas fluorescens 11E preserving valuable properties were derived. Soybean seed treatment with Bradyrhizobium japonicum BIM V-501D and endophytic nitrogen-fixing Rh. radiobacter 27c, phosphate-mobilizing Ps. fluorescens 11E bacteria under model conditions promoted accumulation of nitrogen-fixing bacteria in the root, stem and leaves. The number of nodules rose by 70% compared with the mono-inoculated control; plant height increased by 19%.
