Abstract : One study with the objective of accessing the genetic diversity of pig populations in Ha Gang province was undertaken. Nineteen microsatellites (FAO) were used to genotype 1053 pig individuals. A total 221 alleles were observed. The mean number of alleles per locus was 11.63 ± 3.18 (maximum in locus Sw2410 and minimum in locus Sw2008). In total population, the average observed heterozygote frequency (Ho) was 0,629 (ranged from 0.473 to 0.737) and expected heterozygote frequency (He) was 0.814 (ranged from 0.730 to 0.914). Inbreeding was indicated by heterozygosity deficiency with mean Fis = 0.228. The genetic differentiation between 4 different groups (white, black, brown and black-white pig) was small with a mean Fst = 0.017. The genetic distance was highest between white pig and three other pig groups (black, brown and black-white). There was no significant genetic variation between black and brown pig group (P>0.05). Among 10 district black pig populations, the average allele per population ranged from 7.62 (Meo Vac) to 10.68 (Xin Man), the Fis value was in a range from 0.215 to 0.323. The phylogenetic tree showed that black pig population formed 3 branches: I (Yen Minh, Quan Ba, Dong Van, Meo Vac and Bac Me district), II (Ha Giang, Vi Xuyen and Quang Binh district), III (Xin Man, Hoang Su Phi district).
