Growing along the Niger River, where the species was first domesticated . It is highly likely that humans have independently domesticated two different rice species. African rice is very genetically similar to wild African rice (), as Asian rice is to wild Asian rice (O. rufipogon), and these two divisions have wide genetic differences betwe
Zizania texana is a rare species of grass known by the common name Texas wild rice. It is endemic to Texas, where it is found only on the upper San Marcos River in Hays County. It is threatened by the loss and degradation of its habitat. It is a federally listed endangered species of the United States. [2] [3] [4] [5]
In contrast, the wild ancestor of Asian rice, Oryza rufipogon, often lives for many years, setting seed each year and spreading vegetatively. [6] In addition to these perennial types, some O. rufipogon populations are annuals or intermediate in lifespan. [7] Other wild species in the genus Oryza are also perennial.
Red wild rice had traditionally grown in the marshes of the Camargue. [1] Shortly after World War II vast swaths of salt marshes were desalinated. [1] To boost the local economy, the previous production of salt was replaced by agriculture. [1] Production of white rice was at its peak in the 1960s. [1]

In the late 1600s and early 1700s, tidal swamps bordering rivers were cleared and diked to grow rice. During its peak, 5 million bushels of rice were produced in the United States, and 70% was ...
