Abstract: Nowadays, animal genetic resources are rapidly decreasing due to environmental and economic conditions. In order to protect genetic diversitythat we have, the molecular characterization of domestic animal genetic resources and in vitro conservation studies have been initiated by theTURKHAYGEN-I project. During this project, 11 fieldwork was carried out in 12 different geographical regions for selected horse breeds, whichare Hınıs, Malakan, Canik, Çukurova Horses and Ayvacık Pony. Sampled individuals have been characterized by using 21 autosomal microsatellitemarkers and mtDNA D-loop region seqeuence analysis. According to mtDNA sequence analysis, 68 polymorphic sites and 151 haplotypes(haplotype diversity (Hd)): 0,9866±0,0017, nucleotide diversity (Pi): 0,021±0,00036 and average number of nucleotide differences (k): 8,006) wereidentified among populations. Median-Joining network analysis revealed 54 different haplogroups having non-breed-specific distribution profile.Similarly, breed-specific branching on neighbor joining (NJ) tree drawing by Kimura 2-parameter have not been observed. Calculated Fıs valuesdid not indicate the meaningful deviation from Hardy-Weinberg equilibrium for any populations. More dynamic population structure of horsebreeds compared to other livestock animals, highly changable territories and uncontrolled animal movements cause genetic mixing of Anatoliannative horse populations. Current status shows the requirements of a conscious conservation programs to protect our native horse breeds against theenvironmental and socio-economic pressures.
