Abstract: Analysis of the 110 mtDNA D-loop sequences (930 bp) in some 10 Chinese domestic buffalo breeds revealed that there were 50 different haplotypes and 107 polymorphic sites. The haplotype diversity(Hd) was 0.895 2±0.024 0, the nucleotide diversity(π) was 0.020 0±0.005 6, and the average number of nucleotide differences was 18.445 0. These results showed an abundant genetic diversity in Chinese domestic buffalo breeds. The NJ tree indicated that there were two main maternal origins in those 10 domestic buffalo breeds.
