Abstract
Today, the urgent task is to preserve the gene pool of local and regional breeds with their special and useful traits. These features allow them to represent an additional reservoir of genetic diversity. Analysis of the genetic diversity of three pig populations (Kemerovo pig breed, Kemerovo × Landrace crossbreds and Kemerovo × Landrace × Pietrain crossbreds) by microsatellites showed that significant allelic diversity is observed for some loci, while for others it is low. The highest number of alleles was in the purebred pigs in comparison with crossbreds. The greatest range of alleles per locus was noted in the three-breed cross pigs. The most polymorphic locus in all populations was SO005, and the least polymorphic was SW72. It was noted that for most loci the observed heterozygosity corresponds to the expected one, while for others a shortage of heterozygotes is detected.
