Africa Rice Center

The genebank of AfricaRice is in Cotonou, Benin, where the centre had a temporary headquarters until late 2015. The genebank will be moving back to M’be as part of AfricaRice’s return to its permanent headquarters in Cote d’Ivoire. The collection contains more than 21,000 accessions, the vast majority of them (78%) Oryza sativa, Asian rice. Accessions of the African species O. glaberrima, however, which form 17% of the collections, are crucial to the breeding of varieties able to perform well under the conditions of sub-Saharan Africa.

AfricaRice has distributed about 66,000 samples over the past five years.

About 60% of the accessions are traditional cultivars or landraces, and just under 40% are breeding and research lines. The remainder are mostly wild species.

The base collection at Cotonou, is in medium-term storage at 5-10°C. In addition, AfricaRice has two safety duplicates in long term storage at around -20°C, at Fort Collins, USA, and in the Svalbard Global Seed Vault in Norway. About 40% of the collection is safety duplicated.

The genebank, with its wide range of rice diversity, was a crucial element in the development of very successful Nerica varieties. Much of the research at AfricaRice is focused on screening accessions for their ability to tolerate stresses such as heat and drought and pests and diseases, all of which are expected to increase under climate change.

AfricaRice is spearheading regional characterisation and evaluation efforts throughout sub-Saharan Africa, working 35 national programmes throughout Africa. Other work includes the restoration of lost germplasm after civil strife, provision of conservation services to NARS, and training and capacity building.

The AfricaRice Genebank Information System (ARGIS) holds information on more than 19,000 accessions and is publicly available.

PDCI:护照数据完整性指数
Genesys 会使用 PDCI 作为已发布护照数据的完整性指标。PDCI 使用基因库种质文档中存在或缺失的数据点,以便考虑其他数据点的存在或价值(van Hintum 等人,2011 年)例如,野生种质应具有定义明确的采集站点,但没有品种名称。PDCI 的范围从 0 到 10,其中最低分数 0 表示相当不完整的护照记录,而最高分数 10 则表示非常完整的护照记录。种质的任何类型,野生、地方品种、育种材料或现代变体,都可以达到 PDCI 的最高分。
