For the first time, complete data on the mitochondrial genomes of 6 pig breeds of O, Mong Cai, Muong Khuong, Muong Lay, Huong and Ha Lang were published on GenBank with access codes KX094894, KU556691, KY432578, KX147101, KY964306 and KY800118. The objective of this study was to identify the complete mitochondrial genome of all 6 pig breeds, annotate the genome function, analyze mtDNA polymorphic sequence, thereby serving as a basis for the study of phylogenetic type, identify the origin and evolutionary relationship of these pig breeds with other pig breeds in the world, directly serving the purpose of genetic resource conservation. The results are based on the survey on genetic distance and termites. The phylogenetic relationship indicates the genetic relationship between the 6 indigenous breeds of Vietnam and these indigenous breeds have a close relationship with the South Chinese pig groups and the Yellow River basin. The results of this research are an important source for other research on indigenous pig breeds in Vietnam.
