Three geographically separate domestications of Asian rice

There were three independent domestications of rice in different parts of Asia, according to a new study led by Terence Brown of the University of Manchester, United Kingdom, leading to the four main varieties of domesticated rice —indica, japonica, aus, and aromatic— that are consumed today.

This study introduces a new school of thought, which argues that the variety aus is genetically distinct from the others and proposes the existence of a new locale for its origin. According to the researchers, the separate and independent origin lay somewhere between Central India and Bangladesh.
