Abstract:The giant panda is a characteristic endangered species in our country. Owing to the influence of human activities, the wild giant panda (Ailuropoda melanoleuca) habitats were severely fragmented resulting in restricted gene interflow between the isolated small populations, which perhaps cannot be reinforced or long-term conserved. For protecting the endangered species such as the giant panda, reintroduction captive-bred is one of the effective measures which applied as guidance for reinforcing and establishing sustaining wild population. Such researches have been reported successfully in the past, which indicated that the restricted gene interflow lowered the survive ability in such small isolated populations owing to the effects of inbreeding and genetic drift. Therefore we should consider the genetic background of the current populations first, for the captive giant panda reintroduction aims to improve gene pool of the wild population. The microsatellite and mitochondrial molecular marker analysis show that the existing wild and captive panda populations are still moderate or moderate above genetic level. Populations have a larger evolution potential which provides genetics support for reintroduction. In addition, a relative lower gene diversity was observed in Daxiangling and Xiaoxiangling population. So it is the key to release individual in these populations primarily. Furthermore, Qinling population should be particularly managed and protected in the future. The rational choice concerning on coefficient of kinship, higher preference with genetic diversity, and adverse selection of deleterious gene were emphasized by the genetic matters of reintroduction. This genetic background plays a significant role in reintroduction decision-making of captive-bred. This paper discusses mainly on the genetic diversity and genetic structure within giant panda population in order to provide reference for the success of eventual reintroduction of giant panda into the wild.
