两者均为二倍体(基因组AA，2n=24)。水稻大约在公元1世纪通过来自印度的贸易商(Harlan和Stemler，1976；Ng等人，1991)被引入东非，随后在大约公元1500年由葡萄牙人引入西非(Portères，1962)。根据Portères(1962,1976)的说法，大约公元前3500年，居住在尼日尔河上游内陆三角洲的人们首先驯化了野生祖先O.barthii(以前称为O.breviligulata)。该物种扩散到两个二级驯化中心，一个在冈比亚沿海、卡萨曼斯(塞内加尔)和几内亚比绍，另一个在塞拉利昂和科特迪瓦西部之间的几内亚森林。然而，Harlan和Stemler(1976)提出，在广袤的森林和大草原地区的几个不同的地方驯化了O.arberrima。许多研究已经证实，巴氏原虫是非洲乳杆菌的祖先，两者都局限于西非，而长粒乳杆菌(由其衍生)广泛分布于非洲(Brar和Khush，2003)。引言
(eds M.C.S. Wopereis et al.) 87 O. glaberrima, both of which are diploid (genome AA, 2n = 24). Oryza sativa was introduced to East Africa, probably in the first century AD, via traders from India (Harlan and Stemler, 1976; Ng et al., 1991) and subsequently to West Africa by the Portuguese in about AD 1500 (Portères, 1962). According to Portères (1962, 1976), O. glaberrima was first domesticated from the wild ancestor O. barthii (formerly known as O. breviligulata) by people living in the inland delta of the upper Niger River about 3500 years BP. The species spread to two secondary centres of domestication, one along the coast of The Gambia, Casamance (Senegal) and Guinea-Bissau and the second in the Guinea forest between Sierra Leone and the western part of Côte d’Ivoire. However, Harlan and Stemler (1976) suggest that O. glaberrima was domesticated from O. barthii in several different localities within the vast forest and savannah areas. Many studies have confirmed that O. barthii is the progenitor of O. glaberrima and both are restricted to West Africa, while O. longistaminata (from which O. barthii is derived) is widely distributed in Africa (Brar and Khush, 2003).
