    Abstract:
    The water buffalo (Bubalus bubalis) is an important dairy animal on the Indian subcontinent and in Southeast Asian countries. The diversity and differentiation among 12 populations or breeds of buffalo were studied. Data were generated and analyzed from 527 animals belonging to 10 recognized breeds and 2 additional populations of Indian buffalo by using 22 microsatellite loci. Relationships among buffalo breeds and populations were estimated based on genetic distances. The Bayesian analysis grouped 12 populations into 8 distinctive clusters. Geographically close breeds clustered together, except for the Jaffarabadi and Murrah, which were not in geographic contiguity. The Mantel test revealed nonsignificant correlations between genetic and geographic distances. This supports the hypothesis that buffaloes have been domesticated at different places for specific purposes. The phylogenetic relationship based on microsatellite loci supported the breed classification based on body size. The Toda breed, which is considered to be endangered, had genotypes similar to those of the surrounding buffalo populations.
