A strain of Rhizobium isolated from the root nodule of lentil was caused to produce mutants and screened on a medium of pH 4-5. Five mutant colonies of Rhizobium were isolated from lentil which differed in growth over a pH range 4-5-7.5. Strains differed in their growth in acidic and calcareous soils and also in their effectiveness of N fixation.
