Abstract: Lentil is a very important leguminous pulse crop in Indian agriculture. The unstable trend of lentil production is a major concern for food and nutritional security. Although different districts of West Bengal plays pivotal role in lentil production, very insignificant amount of production comes from the salinity stress affected area. Additionally the suitable Rhizobium strain and their performance in different environmental stress conditions in relation to lentil production is not yet evaluated. In the present study, we are interested to isolate different lentil-specific nitrogen fixing bacterial isolates from Murshidabad district of West Bengal. Sequence analysis revealed that some of the isolated strains are Rhizobium sp. either closely or distantly related to R. leguminoserum. Different isolated strains have been analyzed for salt tolerance. These salt tolerant strains might be useful to make bio-consortium which will be further used to popularize lentil production in the salt affected regions of West Bengal.
