Summary

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.
