Microsatellites – a separate class of molecular genetic markers, are widely used for the study of genetic variability, in particular in populations of animals bred by artificial selection under the influence of microevolutionary processes. The object of study is the gene pool of a population of animals of the Lebedyn cattle breed, which is under threat of extinction. The sample comprised 30 individuals from the farm "Komyshans'ke" in Sumy region. The analysis of population genetic structure was performed using 10 microsatellite loci recommended by FAO-ISAG: ETH225, BM2113, ETH3, BM1818, BM1824, ILSTS006, INRA023, TAGLA053, TAGLA12, ETH10. Amplification products were separated in polyacrylamide gels of different concentrations (5–8%), both native and denaturing. All studied loci were polymorphic. The number of detected alleles per locus ranged from 4 to 8 (on average 5 alleles per locus), the size of which ranged from 115 bp (ETH3) to 307 bp (ILSTS006). The majority of the investigated loci (except ETH3) belonged to valuable informative markers (PIC > 0.5). The most polymorphic TGLA053 (8 alleles), BM2113 (6) and ETH3 (6) loci have been identified. In general, the minimum number of alleles (4) was fixed in 50% loci. The main population genetic parameters for the studied loci have been calculated. The highest values of heterozygosity (He), and effective number of alleles (ne) was characterized for loci BM2113, ILSTS006, TGLA053 and ETH225. With the exception of ETH3 and VM1818 loci, the experimental group of animals is in a state of genetic equilibrium. The average value of the Wright fixation index indicates a tendency to increase in the number of homozygous individuals (inbreeding). Comparative analysis of genetic structure of breeds that have a common origin (Lebedyn (PJSC "Mykhaylivka"), Ukrainian grey (DPDG "Polyvanivka"), Red steppe (DPPR "Stepne"), etc.) has been carried out. The obtained results give grounds to assert that in the experimental population of the Lebedyn breed there are processes that lead to a decrease in genetic diversity. In order to overcome the negative effects of artificial reproduction in the gene pool of small populations of cattle, which include Lebedyn cattle, it is appropriate to use microsatellite markers in the selection and breeding work.

In this work, the genetic diversity of the modern gene pool of the winter rye (S. cereal L.) of the Republic of Belarus from 20 actual breeding samples was investigated using 15 microsatellite (SSR) markers to develop divergent crossing combinations in breeding for heterosis. It was shown that the formed set of SSR markers is highly effective – the informational content index (PIC) varied from 0.50 to 0.83 and averaged 0.72. The most effective microsatellite markers (SCM28, SCM43, SCM101 and SCM102) were identified and can be successfully used to study the genetic diversity of rye. It has been established that the modern gene pool of the winter rye of the Republic of Belarus is generally characterized by fairly wide genetic diversity (interpopulation variability) – all collection samples are characterized by a unique allelic composition of the studied microsatellite loci. Based on investigation results, a hierarchical clustering dendrogram was constructed, which made it possible to determine the most genetically divergent combinations of crosses. The information obtained can be used for the development of an effective scheme allowing to develop new varieties and hybrids in the practical breeding of rye for heterosis.
