R. phaseoli (18 strains) isolated from the bean nodules grown on different soils was studied for lysogeny by EM and cross trial methods. In 9 strains, phage particles were found in culture liquor. The amount of phage in the cultures increases after induction, which proves their true lysogenous state. Morphologically, phages are divided into 3 groups according to the origin of cultures. After cross-planting, the phage could be isolated only in one case-when culture liquor of R. phaseoli K15 was put on the plot of R. phaseoli F2 (phage K15/F2). This phage is morphologically different from the phage particles which are present in the culture liquor of R. phaseoli K15. The origin of the phage K15/F2 is discussed.
