Effectiveness forming and functioning of nitrogen-fixing systems created by soybean (Glycine max (L.) Merr.) and Tn5-mutants of Bradyrhizobium japonicum 646 with different symbiotic properties were studied in green house experiments. Inoculation of seeds by Tn5- mutants 107 and 113 with high virulence, but low activities, lead to decrease of the biometric properties and enhanced yield of plant seeds in comparison with control strains wild 646 and production 634б. Tn5- mutant 118-8 had the low nodulation and nitrogen fixing activities. Inoculation of seeds by high activity mutants 21-2 and 17-2 got reliable increase grain yield of plants in comparison with control. Consequently, this Tn5-mutants may to be used as perspective initial material for the next selection productive nodulate bacteria strains.
