摘要： In contrast to other farm animals, the matrilineal structure of domestic goose has remained an open question. In this study, we analyzed mitochondrial DNA control region sequence variation of 245 domestic geese to discern the main matrilineal components and their phylogenetic relationships. The result of phylogenetic analysis indicated the distinct lineage of clade II and the result of network analysis further suggested the major group of Chinese native goose breeds (subclade S) and introgressive goose breeds (subclade G). Except Yili geese, all Chinese domestic goose breeds were clustered in S, whereas clade II were widely distributed in 2 European breeds, Yili geese as well as 3 domestic Graylag geese. The results support that Chinese domestic goose breeds (except the Yili breed) originated from Swan goose (Anser cygnoides) while European goose breeds originated from Graylag goose (Anser anser). In total, 17 Landoise and 16 White Roman geese were clustered in subclade G together with 1 domestic goose (A. anser, AY112966), which supported the previous finding that European geese originated from Graylag goose (A. anser). But 9 unanticipated samples of two Chinese domestic goose breeds including 7 Lion-head geese and 1 Zhedong White goose in haplotype H9 were also clustered in subclade G as well as 3 Lion-head geese in haplotypes H13, H15 and H16 and 2 Zhedong White geese in haplotypes H18 and H19, which may be caused by the potential gene introgressions between swan goose breeds and graylag breeds with a directional contribution towards graylag geese.
