Certain strains of Rhizobium japonicum fail to produce effective nodules on the soybean variety ‘Hardee,’ Glycine max L. Merr.). F 1 , F 2 , and F 3 generations of Hardee ✕ normal nodulating varieties were used to study the inheritance of the strain‐specific ineffective nodulation of Hardee. Ineffective nodulation was found to be conditioned by a single dominant gene, which was given the symbol R j 2 . Investigation of the parentage of Hardee indicated that the source of this gene was the parent ‘CNS.’
