This paper survey the genetic diversity and population structure of four goat populations of Northeast India including West Bengal. A total of 126 individuals were genotyped at 23 loci so as to support conservation and improvement decisions. The polymorphism of genetic diversity in populations correlated with known population histories. The study identified 440 alleles and most of the studied loci were highly polymorphic. The genetic groups under study presented HWE deviations for least number of the loci. The range of alleles was found to be 1.500 to 9.500 with a global mean of 4.848. The overall mean of observed and expected heterozygosities were 0.484 and 0.493 respectively. The within population inbreeding estimate (FIS) (0.041) indicated moderately high heterozygosity in the populations. Microsatellite analysis revealed moderately high genetic diversity in the studied genetic groups. The Analysis of Molecular Variance (AMOVA) showed that 21% of the total variation was due to differences between genetic groups. The study concluded that appropriate conservation efforts should be undertaken to maintain same levels of genetic diversity.
