title: [Selection methods of nodule bacteria].
abstract: The aim of selecting nodule bacteria is to obtain stable and genetically pure strains with elevated effectiveness in the conditions of symbiosis with bean plants, sufficient viability and competing ability, which would survive in soil for a long time. The following methods have been suggested to solve this task: selection by plants using mutagenic factors; genetic markers; production of genetically homogeneous material; determination of the degree of persistance effectiveness in mutants.
