Abstract: According to the public declaration by commercial companies, the commercial fatty liver line of Landes geese is grey feather. However, about 0.3% varieties of pure white or white with grey spots feather phenotype were observed in our purebred stock. So, we tentatively put forward a doubt whether some alien genetic components coexist in this commercial line. In order to prove this proposition, the mtDNA D-loop sequence variation were analyzed among 115 domestic goose individuals from this commercial fatty liver line and Chinese indigenous breeds. Total 11 haplotypes were determined and all, which could be classified into Asian haplogroup and European haplogroup. Seven landes geese residing in the E1-E3 haplotypes were clustered into the European haplogroup together with the wild greylag geese, while the remaining 45 Landes geese were grouped into the Asian haplogroup, which was predominantly occupied by the Chinese geese haplotypes. Although, the frequency (45/52) would be overestimated, we also reasonably believed that the matrilineal components of Chinese geese coexist in this commercial fatty liver line of Landes geese. In addition, the extremely low genetic diversity has been retained in the 2 sampled populations of Chinese geese, especially, in Wanxi white geese population.
