Goat production is considered to be very important for its contribution to the development of rural area.China owns a great variety of domestic goat genetic resources.We present herein the phylogenetic relationships of 33 Chinese domestic goat breeds reared throughout China by systematical investigation into their mtDNA variability,then discussed the Chinese goat ecological regionalization with genetic information.
