Evidence for the Emergence of New Rice Types of Interspecific Hybrid Origin in West African Farmers' Fields [PDF]

, 2009
In West Africa two rice species (Oryza glaberrima Steud. and Oryza sativa L.) co-exist. Although originally it was thought that interspecific hybridization is impossible without biotechnological methods, progenies of hybridization appear to occur in ...
