Summary:The present work was carried out with the aim to determine the effect of Rhizobium isolates previously characterized and genetically identified on morphological and physiological parameters and the nitrogen fixation of common bean genotypes. The phenotypic analysis of isolates carried out under controlled conditions, where the nodulation, morphological and physiological parameters and the nitrogen fixation of the genotypes ICA Piajo and BAT-304 were evaluated. The results showed that the isolated strains have the ability for abundant nodule formation in roots plant of both genotypes analyzed. The remarkable beneficial effect was for R. etli specie and the isolates from Santa Clara and Camajuaní-1, as well as the isolated of R. pisi from Camajuaní-2. The genotypic variability showed the close positive correlation among these strains and the genotype BAT-304 compared with ICA Pijao.
