Vietnam is one of the most important countries for pig domestication, and a total of 26 local breeds have been reported. In the present study, genetic relationships among the various pig breeds were investigated using 90 samples collected from local pigs (15 breeds) in 15 distantly separated, distinct areas of the country and six samples from Landrace pigs in Hanoi as an out-group of a common Western breed. All samples were genotyped using the Illumina Porcine SNP60 v2 Genotyping BeadChip. We used 15 160-15 217 SNPs that showed a high degree of polymorphism in the Vietnamese breeds for identifying genetic relationships among the Vietnamese breeds. Principal components analysis showed that most pigs indigenous to Vietnam formed clusters correlated with their original geographic locations. Some Vietnamese breeds formed a cluster that was genetically related to the Western breed Landrace, suggesting the possibility of crossbreeding. These findings will be useful for the conservation and management of Vietnamese local pig breeds.
越南是猪驯化的最重要国家之一，共报道了26个本地品种。在本研究中，使用从该国15个相距遥远、不同地区的本地猪（15个品种）收集的90个样本以及来自河内长白猪的6个样本作为常见西方品种的外群，研究了各种猪品种之间的遗传关系。所有样本均使用Illumina Porcine SNP60 v2基因分型芯片进行基因分型。我们使用了15160 - 15217个在越南品种中显示出高度多态性的单核苷酸多态性（SNP）来确定越南品种之间的遗传关系。主成分分析表明，大多数越南本土猪形成了与其原始地理位置相关的聚类。一些越南品种形成了一个与西方品种长白猪有遗传关系的聚类，这表明存在杂交的可能性。这些发现将有助于越南本地猪品种的保护和管理。
