AB  - Genetic distance and gene flow of all pairwises of 14 Chinese indigenous chicken breeds and one jungle fowl and their relations with geographical distances were evaluated in the present study. The pairwise F<SUB>ST</SUB>/(1-F<SUB>ST</SUB>) of 15 Chinese chicken breeds was evaluated by 29 microsatellite loci. The results showed that the number of alleles per locus was ranged from 2-25 and the average of expected heterozygosity and PIC of all loci were 0.6683 and 0.50, respectively. The average of genetic differentiation among population measured as FST value, was 16.4% (p< 0.001), all loci were contributed significantly (p< 0.001) to this differentiation. Red jungle fowl and Gushi chickens were observed distant genetic relationship with other breeds, whereas Huainan Partridge and Tibetan chickens were observed close relationship with other breeds. The geographical elements may own the close relationship for particular population pairs. However, the equation F<SUB>ST</SUB>/ (1-F<SUB>ST</SUB>) = -0.0162 + 0.0313ln (d) and the result of Mantel’s test (p = 0.054) did not provide enough support for a significant correlation between the genetic and geographical pairwise distances.
