Abstract Four soybean genotypes were sampled in eight different plantings during the years 1967 and 1968, to determine the variability in Rhizobium japonicum population. Considerable variability occurred among locations in the serological distribution of nodules in the cultivar ‘Lee.’ The serogronp patterns for nodules formed on soybean genotypes D49‐772 and D55‐4102 were different from those formed upon Lee at several of the locations. Results indicate that an effective relationship can be established between a soybean genotype and a wide range in serogroups of R. japonicum .
