We show that the diversity of the wild population with ten lineages is nearly double that of the domestic population with 12 lineages in China. The domestic lineages identified in this study together with the other domestic lineages isolated world-wide share a common recent ancestor, suggesting the origin of the domestic population through a single bottleneck .
