Outline of Final Research Achievements

In the present study we investigate genetic diversity and relation of Asian native horse populations using DNA samples collected from mountainy ranges Myanmar, Laos, and Vietnam. We collected 184, 71, and 167 DNA samples of native horses in Myanmar, Laos, and Vietnam, respectively, and investigated haplotypes of mitochondrial DNA and Y chromosomal markers as well as genotypes of microsatellite markers and several functional genes. The results indicated that genetic diversities of maternal lineages are high in these populations and the have unique genetic compositions, while a part of these populations showed genetic influences of western breeds in paternal lineage.
