Genetic studies of apricot are the actual direction in the genetics of fruit crops. In this regard, the improvement of the collection of SSR markers for the genotyping of this culture is an objectively significant task. In a study for the 16 SSR-markers previously developed on almonds (PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1, PdUnchar2, PdSLD1, PdGMGT1, PdTrTFGT1) and Siberian apricot (A3-72, A1-63, H2-22, A3- 7-1, H2-5, A1-7, A3-9, H2-45), approbation and evaluation of the prospects of using for genotyping Prunus armeniaca L. were performed. Approbation, performed on 3 varieties of different origin, revealed markers and their combinations optimal for their use. During the study, all tested DNA markers were grouped into multiplex sets, including 4 markers. This allows carrying out genotyping simultaneously on 4 loci in the formulation of one reaction. One marker (PdUnchar2) from the studied sample included in the multiplex set did not show amplification. Five markers gave a monomorphic product. The remaining 11 SSR markers allowed us to obtain polymorphic, cultivar-specific SSR fingerprints for all the studied cultivar. These multiplex sets are proposed for use in studying the genetic polymorphism of the species Prunus armeniaca L.
