The inheritance of nodulation and non-nodulation of nodule bacterium on soybean roots was studied in four crosses and three back cross combinations. Nodulating and non-nodulating and plants in hybrid populations were checked individually, and the results obtained are summarized as follows. Single dominant genes which are governed on nodulating of nodule bacterium on roots of female parents, Sunbijabikong, Kyung Nam No. 1, Kyung Nam No. 2 and Ulsan. It was also found that single recessive genes which are conditioned on non-nodulating of nodule bacterium on roots of male parent namely D68-0099. It could be concluded that the non-nodulating line, D68-0099, is conditioned by the single recessive genes designated as rj1 rj1, and their non-nodulating isolines could be used as tools to measure nitrogen fixation and residual nitrogen in soils.
