Nitrogen is a key limiting nutrient for agriculture. The association among diazotrophic bacteria and legumes is an important technology to supply nitrogen to the plant without major environmental impacts, and encourages the development of sustainable agriculture. Aiming to evaluate the nodulation of 882 Mesoamerican and Andean genotype of common bean a greenhouse experiment was carried out at the National Rice and Beans Research Center of Embrapa, located in the county of Santo Antônio de Goiás, Goiás, Brazil. The experiment was performed on a randomized block design, in which the genotypes of common bean, obtained from the active bank of genotype of the Embrapa Rice and Beans, were evaluated under sterile conditions.
