Oryza barthii A. Chev.

Oryza barthii

provided by wikipedia EN

Oryza barthii, also called Barth's rice,[3] wild rice,[4] or African wild rice,[5] is a grass in the rice genus Oryza. It is an annual, erect to semierect grass. It has leaves with a short ligule (<13 millimetres (3364 in)), and panicles that are compact to open, rarely having secondary branching. The inflorescence structure are large spikelets, 7.7–12.3 millimetres (391283164 in) long and 2.3–3.5 millimetres (2325635256 in) wide, with strong awns (up to 20 centimetres (8 in) long), usually red. The inflorescences have anthers 1.5–3 millimetres (1525615128 in) long.

This wild rice grows in sub-Saharan Africa, and is found in mopane or savanna woodland, savanna or fadama. O. barthii grows in deep water, seasonally flooded land, stagnant water, and slowly flowing water or pools; it prefers clay or black cotton soils (vertisol), and is found in open habitats.[6] It is the progenitor of cultivated Oryza glaberrima, African rice.[7][8]

It has nodal roots hosting nitrogen fixing, photosynthetic strains of Bradyrhizobium.[9]

The sequenced genome of O. barthii was published in 2014.[10] This species is one of the AA species, the domesticated rices and their wild relatives.[8]

Distribution

O. barthii is primarily found in West Africa.[8]

Oryza barthii ( French )

Oryza barthii, le riz sauvage d'Afrique, est une espèce de plantes monocotylédones de la famille des Poaceae, sous-famille des Oryzoideae[2], originaire d'Afrique. Ce sont des plantes herbacées annuelles, aquatiques, aux tiges (chaumes) géniculées ascendantes ou décombantes, pouvant atteindre 60 à 120 cm de long, aux inflorescences en panicules[2]. Cette espèce sauvage, proche parente du riz africain (Oryza glaberrima), est considérée comme l'ancêtre de ce dernier[3]. C'est une mauvaise herbe des rizières d'Afrique occidentale, notamment au Mali, mais également au Ghana, en Côte d'Ivoire, Sierra Leone, Nigeria, Niger et au Tchad[4].
