A recent breakthrough in inter-specific hybridization between African indigenous rice, O. glaberrima, and Asian rice, O. sativa, has helped developing highly weed competitive upland rice cultivars with a yield potential greater than that of the currently cultivated improved and traditional rices in West Africa.

Heading date gene, dth3 controlled late flowering in O. Glaberrima Steud. by down-regulating Ehd1
Plant Cell Reports, 2011Heading date in rice is an important agronomic trait controlled by several genes. In this study, flowering time of variety Dianjingyou 1 (DJY1) was earlier than a near-isogenic line (named NIL) carried chromosome segment from African rice on chromosome 3S, when grown in both long-day (LD) and short-day (SD) conditions.

Neighbour Effects Between two Co-Occurring Rice Species, Oryza sativa and O. Glaberrima
The Journal of Applied Ecology, 1984(1) Two rice species, Oryza sativa and 0. glaberrima, are often found growing together in farmers' fields in West Africa. The effects of species coexistence in a plant community on the interactions between plants were studied using four strains of these two sympatric species collected from upland and lowland fields in Nigeria.

Interspecific Oryza Sativa L. X O. Glaberrima Steud. progenies in upland rice improvement
Euphytica, 1997Fertile interspecific progenies between Oryza sativa L. and O. glaberrima Steud. were produced through backcrossing and doubled haploid breeding (DHB). Backcrossing with the O. sativa parents increased fertility and helped combine the O. sativa and O. glaberrima features.

Miniature Ping (mPing) is the first active miniature inverted-repeat transposable element to be identified in rice, and its mobilization is activated by stress treatments. We have examined the mobilization of mPing in four NERICA (New Rice for Africa) lines and 13 interspecific lines. All 17 lines are inbred progenies derived from crosses between Oryza

Interspecific cytoplasm substitutions of an Indica strain of Oryza sativa L. and O. Glaberrima Steud
Euphytica, 1985To study differential nucleus-cytoplasm interactions between the two cultivated rice species, Oryza sativa and O. glaberrima, cytoplasmic substitution lines were made by using a glaberrima strain (G) and an Indica strain of sativa (S). The G cytoplasm had no adverse effect on pollen development when combined with the nucleus of S.

Weed competition is the most important yield-reducing factor in upland and hydromorphic rice environments in Africa. Many of the commonly grown tropical japonica varieties have a high yield potential, but they compete poorly with weeds. By contrast, the indigenous cultivated Oryza glaberrima landraces are highly competitive due to high tillering ...
