Most cultivated varieties of Oryza sativa and Oryza glaberrima , however, have lost the ability to form long awns. West Himalaya, GrassBase - The Online World Grass Flora Fruits: The fruit is a caryopsis (a dry fruit where the fruit wall is attached to the seed). Oryza glaberrima is the African cultivated rice species, domesticated from its wild ancestor by farmers living in Inland Delta of Niger River. Pressed and dried specimens ofAfrican rice are held in Kew's Herbarium, where they are available to researchers by appointment. The large average genetic distance between O. glaberrima and O. sativa could become a reproductive barrier and cause interspecific hybrid sterility. As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. The spikelets are about 8 mm long and remain on the plant when mature. It is a seed of Oryza glaberrima or L. Oryza sativa. (2009). African rice is still an important crop for small-scale farmers who grow it for its nutty flavour and other culinary qualities. The spikelets (clustered units of flowers and bracts) are solitary. Oryza glaberrima, commonly known as African rice, is a domesticated rice species. Rice (Oryza sativa) is a type of [vegetables] and food. Humans have independently domesticated two different rice species. Today Oryza barthii can be found growing wild in parts of Africa. As a common grain, rice is the most widely consumed human staple food. A checklist of Gambian plants: 1-33. Boudet, G., Lebrun, J.P. & Demange, R. (1986). Rice Res. Michael Jones, The Gambia College.

In Africa, both African rice (Oryza glaberrima Steud.) Guinea, (1972). Botanical Survey of India, Calcutta. There are only two species of cultivated rice in the world: Oryza glaberrima, or African rice, and Oryza sativa, or Asian rice.Native to sub-Saharan Africa, O. glaberrima is thought to have been domesticated from the wild ancestor Oryza barthii (formerly known as Oryza brevilugata) by peoples living in the floodplains at the bend of the Niger River some 2,000–3,000 years ago (1, 2).

However, increasingly African rice is being replaced by the introduced Asian varieties of Oryza sativa, which produce a higher yield than African rice, shatter less easily and have a softer grain that is easier to mill. Furthermore, seeds of rice are utilized as bioreactors for manufacturing human pharmaceuticals including peptides or therapeutic proteins. & Lebrun, J.-P. (1976). Institut d' Elevage et de Médecine Vétérinaire des Pays Tropicaux, Maisons Alfort. Oryza glaberrima  is thought to have been domesticated from its wild ancestor  Oryza barthii  around 1,500 BC in the inland delta of the Niger River. Tabulated data are presented on the dormancy of 28 varieties from Nigeria and twelve from the stock maintained at the Central Rice Research Institute. Our analyses showed genetic structure within O. glaberrima that has a geographical association. & Boudet, G. (1991). Its ancestor, which still grows wild in Africa, is Oryza barthii. World Grass Species - Synonymy database The Board of Trustees of the Royal Botanic Gardens, Kew. African rice Oryza glaberrima (2n = 24, AA) has many unique traits such as weed competitiveness, drought tolerance and the ability to grow under low input conditions. Furthermore, seeds of rice are utilized as bioreactors for manufacturing human pharmaceuticals including peptides or therapeutic proteins. Today  Oryza barthii  can be found growing wild in parts of Africa. O. glaberrima genotype is a closely related species within the genus Oryza and could be useful for broadening the genetic basis of O. sativa and increasing the rice genetic diversity. Based on our germplasm distribution database from 1995 to 2019, we found out that nearly 86% of the Oryza glaberrima collection has been distributed to users on average six-times (ranged between 1 and 133 times during the 25 years). The project aims to protect, collect and prepare the wild relatives of 29 key food crops, including African rice, so that they are available to pre-breeders for the development of new varieties that are more resilient to the effects of climate change.
