The Kyrgyz native horse (KH) is one of the economically and traditionally important livestock in the Kyrgyz Republic, representing the history and values of the Kyrgyz people. The Objectives of this study were to determine the genetic diversity, structure, and characteristics of KH through comparative analysis with Korean horse breeds. The KH and three Korean breeds (Jeju horse, Jeju crossbred, throughbred) were characterized by using 19 microsatellite markers. The mean observed and expected heterozygosities were 0.689 and 0.794, respectively. The mean number of alleles for the KH was 9.474. The polymorphism information content (PIC) showed that six loci (AHT4, TKY297, VHL20, LEX3, ASB17 and HTG10) were highly polymorphic (> 0.8). The Phylogenetic analysis, factorial correspondence analysis (FCA) and admixture analysis showed that four breeds were separated into four different populations. Based on these results, it is considered that steady management planned breeding considering inbreeding is necessary for the continued presevation of KH, and it could be used as a basis for future genetic resource maintenance and conservation planning.
