Description

Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. It was first domesticated and grown in West Africa around 3,000 years ago. In agriculture, it has largely been replaced by higher-yielding Asian rice (O. sativa), and the number of varieties grown is declining. It still persists, making up an estimated 20% of rice grown in West Africa. It is now rarely sold in West African markets, having been replaced by Asian strains. In comparison to Asian rice, African rice is hardy, pest-resistant, low-labour, and suited to a larger variety of African conditions. It is described as filling, with a distinct nutty flavour. It is also grown for cultural reasons; for instance, it is sacred to followers of Awasena (a traditional African religion) among the Jola people, and is a heritage variety in the United States. Crossbreeding between African and Asian rice is difficult, but there exist some crosses. Jones et al. 1997 and Gridley et al. 2002 provide hybrids combining glaberrima's disease resistance and sativa's yield potential.
