In the conditions of laboratory experiment with chickpea plants of the varieties Golden Jubilee, Avatar, Krasnokutsky 36, the interaction with various strains of the genus Mesorhizobium was studied – 039, 065, 068, 520, 527, 1305, A-44. A comparative assessment of the phenotypic characteristics of chickpeas, including the number of nodules, was made, the total DNA of nodules was isolated and analyzed by the saAFLP method. The largest number of nodules in chickpea plants of the Golden Jubilee variety was formed during inoculation with strains 039 and 520; in the variety Krasnokutsky 36 when inoculated with strains 065,520 and A-44, in the Privo variety when inoculated with strains 065, 068 and 1305. The most effective "variety-strain" pairs have been identified. The strain Mesorhizobium ciceri 039 prevails in most nodules on the roots of plants of all studied varieties, which allows us to recommend this strain (genotype) as the basis of a biological preparation for pre-sowing treatment of chickpea seeds
