Salinity is one of the most brutal environmental factors limiting the productivity of crop plants because most of the crop plants are sensitive to salinity caused by high concentrations of salts in the soil, and the area of land affected by it is increasing day by day. Now we focused the native rhizobia from Tsunami affected area of Cuddalore district. In this study, total thirty rhizobial isolates were tested different concentration of NaCl level. Among the thirty isolates such as GNBJ-4, GNBJ-8, GNBJ-9 and GNBJ-28 recorded the maximum of salt stress upto 3.0% of NaCl. Further this four isolates recorded the maximum of IAA, EPS production, number of nodules, nodule ARA activity and nodule N content at 3.0% NaCl concentration respectively. The four isolates of B. japonicum namely GNBJ-4, GNBJ-8, GNBJ-9 and GNBJ-28 were selected for further study of mutation efficiency
