title: [Analysis of genetic variations in different goose breeds using microsatellite markers].
abstract: The genetic diversity of six goose breeds (White Goose, Zi Goose, Huoyan Goose, Wanxi Goose, Rhin, Landoise) was analyzed using microsatellite markers. Heterozygosity(H), polymorphism information content (PIC) and genetic distances were calculated for each breed based on the allele frequency. Results showed that 7 microsatellite sites were highly polymorphic, and could be used as effective markers for analysis of genetic relationship among different goose breeds. The mean heterozygosityies of were between 0.6617 (Rhin) and 0.8814 (Zi goose), among six goose breeds, the lowest was Rhin goose (0.6617) and the highest was Zi goose (0.8814). The range of mean PIC was between 0.6145 and 0.7814, which was in the similar range as the mean heterozygosities. Based on the UPGMA cluster analysis results, six goose breeds were grouped into classes, White, Zi, Huoyan and Wanxi Goose in one class, and the foreign breeds of Rhin and Landoise goose in another class. These results indicated that the dendrogram obtain from genetic distance could be used to correctly reflect the phylogenetic relationship among the six goose breeds, suggesting that microsatellite DNA marker is a useful tool to determine the genetic diversity in closely related breeds.
