Özet: The present study was performed to reveal genetic variability of autochthonous Güney Karaman sheep breed, which is conserved as a genetic resource, using sixteen microsatellites marker recommended by FAO. Animal material for the study was consisted of 119 Güney Karaman sheep raised in Bahri Dagdas International Agricultural Research Institute. A total of 277 alleles were detected from sixteen markers studied. Although total population size is very limited, the mean number of alleles (17.31), observed heterozygosity (0.81) and polymorphic information content (0.82) findings indicated that noticeable genetic variability in this population. Ten out of the sixteen microsatellite markers studied had a positive FIS value. The mean value of FIS was 0.042. The infinite allele model (IAM), two-phase mutation model (TPM) and stepwise mutation model (SMM) in the Bottleneck software were used to check genetic bottleneck. The L-shaped curve obtained from analyze indicates absence of bottleneck in Güney Karaman sheep population. These results will help to develop conservation strategies for the Güney Karaman sheep population.
