|Seeds of Oryza glaberrima|
Oryza glaberrima, commonly known as African rice, is a domesticated rice species. It is believed to have been domesticated 2000–3000 years ago in the inland delta of the Upper Niger River, in what is now Mali. Its wild ancestor, which still grows wild in Africa, is Oryza barthii.
This species is grown in West Africa. African rice often shows more tolerance to fluctuations in water depth, iron toxicity, infertile soils, severe climatic conditions, and human neglect, and exhibits better resistance to various pests and diseases, such as nematodes (Heterodera sacchari and Meloidogyne spp.), African rice gall midge (Orseolia oryzivora), rice stripe necrosis virus, rice yellow mottle virus, and the parasitic plants Striga. The species shows several negative characteristics with respect to the Asian rice species O. sativa, such as brittle grain and cracking during industrial polishing. More importantly, it consistently shows lower yields than O. sativa.
The genome of O. glaberrima has been sequenced, and was published in 2014.
