| Abstract | Afin de comparer la diversité actuelle des écotypes de fonio à celle cultivée dix (10) ans plus tôt au Bénin, une enquête a été menée en 2013 dans la commune de Boukoumbé. Dans chacun des vingt (20) villages prospectés, un focus groupe d’une douzaine de producteurs a été à chaque fois enquêté. Cinq (5) à dix (10) producteurs sont ensuite entretenus individuellement à l’aide d’un questionnaire semi-structuré pour recueillir des informations sur les cultivars, leurs noms locaux, leurs principales caractéristiques, et la gestion des semences. Les résultats ont confirmé la diversité des appellations et ont permis de recenser cinq (5) cultivars différenciés par la précocité, la couleur des racèmes, les tailles de graines et de plantes. Les semences, transmises surtout de génération en génération, sont prélevées à 99% sur les récoltes précédentes. Près de 95% des enquêtés cultivent une seule variété à la fois. La plus forte diversité a été rencontrée chez les "Ditamaris" des villages de Boukoumbé-centre et Natta. "Iporapia" et "Takotapuaka" sont cultivés par toutes les ethnies. La diversité décrite dix (10) ans plus tôt dans la zone a été maintenue. Toutefois, les variétés de précocités extrêmes sont de moins en moins cultivées, et donc menacées de disparition.© 2015 International Formulae Group.

In each of the twenty (20) villages surveyed a focus group of a dozen producers was investigated every time. Then, five (5) to ten (10) producers are individually interviewed using a semi-structured questionnaire to collect information on cultivars, their local names, their main characteristics and seed management. The results confirmed the diversity of names and allowed to identify five cultivars differentiated by the earliness, color of racemes, sizes of seeds and plant height. Seeds, especially transmitted from generation to generation, are taken at 99% on the previous harvest. Nearly 95% of respondents grow only one variety at a time. The greatest diversity was encountered among the "Ditamaris" of villages in Boukoumbé center and Natta. "Iporapia" and "Takotapuaka" are cultivated by all ethnic groups. The diversity described ten (10) years earlier in the area has been maintained. However, the extreme precocity varieties are lesser and lesser grown, and therefore at risk of extinction.© 2015 International Formulae Group. All rights reserved. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
