Abstract:
:To determine genetic diversity and evolutionary relationships among Chinese buffalo populations, 18 indigenous swamp buffalo populations and two introduced river buffalo breeds were genotyped for 30 microsatellite loci. The mean number of alleles across the 30 loci was 8.13, and the expected heterozygosity ranged from 0.517 (Yanjin) to 0.609 (Dehong). Although there was abundant genetic variation, genetic differentiation between Chinese buffalo populations was low, with only 2.8% of the total genetic variance among populations. The genetic differentiation pattern and genetic relationships among Chinese buffalo populations were consistent with their geographic distribution. The Dehong population was discerned as a distinct indigenous population, but suffered genetic admixture with river buffalo. The remaining populations were divided into four major clusters, i.e. the Upper and Middle Reaches of Yangtze Valley cluster (Guizhou, Guizhoubai, Yanjin, Fuling, Enshi and Jianghan), the Lower Reaches of Yangtze Valley cluster (Haizi, Shanqu and Dongliu), the South China cluster (Fuan and Xinfeng) and the Southwest China cluster (Xinglong, Xilin, Diandongnan and Dechang).
