Abstract
In this study, partial mitochondrial DNA (mtDNA) D-loop sequences of three Vietnamese indigenous chicken varieties, including Mong Tien Phong, To, and Sau Ngon, were analyzed to access genetic diversity and the maternal lineages of origin. A 525 bp fragment of the mtDNA D-loop region was sequenced from a total of 61 chickens of the three varieties. A neighbor-joining phylogenetic tree was assembled from the haplotypes obtained and reference sequences of mtDNA D-loop sequences of Red Junglefowl and domestic chickens from National Center for Biotechnology Information database. Genetic diversity indices and analysis of molecular variance were performed. Evaluation of genetic relationships between the three varieties was carried out with pairwise fixation index (FST). In total, 16 haplotypes were identified in the chickens studied. These haplotypes were classified in three haplogroups (A, B, and E) with the majority grouped in haplogroup B and haplogroup E. All three chicken varieties studied were distributed into 2–3 haplogroups and all three haplogroups found in this study are also represented by Red Junglefowl. In conclusion, all three Vietnamese indigenous chicken varieties have likely originated from multiple maternal lineages and potentially descended from the Red Junglefowl.
