Indigenous races in each country are as a national capital and strategic product in the economy and prosperity of the country that maintenance of these races are very valuable. Due to the importance of maintaining diversity and identification of genetic resources in indigenous breeds, five breeds of Iranian sheep population (Arabi, Arman, Dalagh, Karakul and Lory) using four microsatellite markers (McMA2, McMA26, OarHH35 and BM6444 ) was evaluated in terms of genetic diversity. Genomic DNA was extracted from 225 blood samples by optimized salting-out DNA extraction procedure. The PCR reactions were successfully performed with all primers. The results showed that all loci were quite polymorph. Hardy-Weinberg equilibrium test using chi-square test showed that some various combinations of loci-population were in a state of Hardy-Weinberg disequilibrium (P<0.05). The highest number of alleles was observed in loci of McMA2, McMA26 and OarHH35 of Dalagh, Arabic, Lory and Karakul populations respectively (12 alleles) and the lowest number of alleles for OarHH35 in Dalagh population. The maximum expected heterozygosity in combination locus-population of loci McMA2، McMA26، OarHH35، BM6444 were 0.885, 0.9, 0.88 and 0.87 respectively. With respect to the studied loci, it is concluded that all studied sheep populations have wide genetic diversity.
