GENETICAL RESEARCH OF ORIGIN OF ASIAN SUSPOPULATIONS IN VIETNAM

本研究的目的是通过形态和遗传分析来确定东亚野猪和家猪的起源是否位于越南。从2002年到2004年的三年时间里，我们走访了越南北部、西部和中部地区的几个当地村庄，收集了野猪和本地猪的样本。形态学分析方面，测量了从村庄采集的猪骨，进行了遗传分析，收集了本地猪的子猪和肉猪，从样本中分离了总DNA，并从DNA样本中扩增了线粒体DNA。对248份DNA样本进行了测序和系统发育分析。得到了以下结果：1)琉球野猪与越南野猪有亲缘关系。2)越南野猪和家猪具有显著的遗传多样性。越南猪，包括野生猪和家猪，可能与其他东亚猪有共同的祖先。3)越南猪的形态和遗传分析将为了解东亚驯养猪的历史提供重要信息，因为越南猪饲养了几种不同大小或饮食习惯的猪。本研究的一部分已经发表在论文中，其他部分现在正在论文中准备。

The purpose of this research is to characterize whether the origin of East Asian wild boar and domestic pigs is located in Vietnam by morphological and genetic analyses. For three years from 2002 to 2004, we visited several local villages to collect samples from wild boar and native pigs in North, West and middle areas of Vietnam. About morphological analysis, Sus bones collected from villages were measured, whereas, genetic analyses were conducted to collect heir and meat from native pigs, isolate a total of DNA from the samples and amplify mitochondrial DNA from DNA samples. A total of 248 DNA samples were sequenced and phylogenetic analized. The following results were obtained.1)Ryukyu wild boar was genetically related to Vietnamese wild boar. The present results supported the hypothesis that Ryukyu wild boars are a unique species established on isolated Ryukyu Islands.2)Vietnamese wild boars and domestic pigs possess remarkable genetic diversity. Vietnamese pigs, including wild and domestic pigs may share a common ancestor with other East Asian pigs.3)Morphological and genetic analyses of Vietnamese pigs will provide important information about the history of domestication pig in East Asian, because several pigs with different size or food habit are raising.A part of this research has been published in a paper, the other parts are now prepared in the papers.
