Summary The study characterized genetic diversity and genetic structure of five indigenous pig populations ( Ha Lang , Muong Te , Mong Cai , Lung and Lung Pu ), two wild pig populations ( V ietnamese and T hai wild pigs) and an exotic pig breed ( Y orkshire) using FAO / ISAG recommended 16 microsatellite markers in 236 samples. All estimated loci were very polymorphic indicated by high values of polymorphism information content (from 0.76 in S0225 to 0.92 in Sw2410) . Indigenous populations had very high level of genetic diversity (mean He = 0.75); of all indigenous breeds, Lung Pu showed highest mean number of alleles ( MNA = 10.1), gene diversity (He = 0.82), allele richness (5.33) and number of private alleles (10). Thirteen percentage of the total genetic variation observed was due to differences among populations. The neighbour‐joining dendrogram obtained from Nei's standard genetic distance differentiated eight populations into four groups including Y orkshire, two wild populations, M ong Cai population and a group of four other indigenous populations. The B ayesian clustering with the admixture model implemented in Structure 2.1 indicated seven possible homogenous clusters among eight populations. From 79% ( H a Lang ) to 98% ( M ong Cai ). individuals in indigenous pigs were assigned to their own populations. The results confirmed high level of genetic diversity and shed a new light on genetic structure of Vietnam indigenous pig populations.
