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村庄，收集了野猪和本地猪的样本。在形态分析方面，从农村采集的苏骨进行了测量，而遗传分析则收集了当地猪的继承人和肉，从样品中提取了全部DNA，并从DNA样品中扩增了线粒体DNA。对248个DNA样本进行了测序和系统发育分析。研究结果表明：1)琉球野猪与越南野猪有亲缘关系。本研究结果支持琉球野猪是孤立琉球岛上独有物种的假说。2)越南野猪和家猪具有显着的遗传多样性。越南猪，包括野猪和家猪，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化猪的历史提供重要信息，因为有几头不同体型或食性的猪正在饲养。

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.
