Soybean genotypes grown successive years in different fields were predominantly nodulated by Rhizobium japonicum strains of specific scrogroups. Chi‐square analyses showed significant differences among plant genotypes in their acceptance of Rhizobium japonicum strains of specific serogroups. Closely related soybean genotypes had similar distributions of R. japonicum in their nodules. The results indicate specific interactions between soybean genotypes and R. japonicum serogroups hi nodule formation.
