There has been studied the nodulation competitiveness of Tn5 mutants of pea rhizobia which were obtained from Rhizobium leguminosarum bv. viciae 263 б and which had high nitrogen fixing activity and promoted the increase of both nodule number and aboveground biomass in comparison with wild strains. It was shown that the competition ability of M1 and М68 mutants did not differ from the competitive ability of strains 263 б and Rhizobium leguminosarum bv. viciae 245 a of industrial strains.
