Abstract The applicability of 14 pairs microsatellite primers of blue peafowl and green peafowl to white peafowl population was analyzed in the present paper, and the results showed all 14 pairs of microsatellite primers could produce specific allele patterns. A mean of 1.71 alleles was found for each locus. Seven pairs were highly polymorphic, MCW0080 and MCW0098 were ideal markers for peafowl. Genetic diversity analysis of three peafowl populations demonstrated that the heterozygosity and the genetic diversity of these peafowl populations were very low, the expected heterozygosity of white peafowls, green peafowl and blue peafowl population were 0.2579, 0.2482 and 0.2744, respectively. Genetic differentiation index (FST) of these populations was 9.7% and there was significant genetic differentiation among three populations(P<0.001). The result showed that white peafowl has a closer relationship with blue peafowl than with green peafowl, Reynolds' genetic distance and gene flow between the two populations were 0.0295 and 8.6112, respectively. The results of this study support that white peafowl is not subspecies but a line belonging to blue peafowl.
