Bambara groundnut (Vigna subterranea l.), third food legume in Africa, is the largest in terms of production and consumption after the peanut (Arachis hypogeae) and Cowpea (Vigna unguiculata walp.). The valorisation of this culture is one of the best alternatives to ensure the food security of populations faced with the decline in the production of food crops such as millet, sorghum or wheat. To achieve this goal, a better knowledge of the genetic diversity of this culture is more than necessary. Therefore, followed by exploration of accessions collection was made across the country. All the areas visited were geo referenced and a map has been prepared. In total one hundred and fifteen (115) Bambara groundnut accessions were collected within six (6) regions of Niger with fifty (50) locations visited throughout the different growing areas. Fourteen morphotypes numbered Ne-01 to Ne-14 were identified after the collection. Following carried out discussions, the yellow color Ne-01 morphotype is the most appreciated both by producers and consumers. It is also clear that this culture of Bambara groundnut is practiced on small areas by both women and men. The choice of the seedling period is the same as well among women than among men. The production is destined for self-consumption or for sale depending on the quantity harvested. Chemicals, ash, salt, natron, cans are commonly used for the seeds conservation. Several types of dishes are made based of Bambara groundnut. In addition, Bambara groundnut has therapeutic values in some farmer's areas.

Abstract
Bambara groundnut (Vigna subterranea l.), third food legume in Africa, is the largest in terms of production and consumption after the peanut (Arachis hypogeae) and Cowpea (Vigna unguiculata walp.). The valorisation of this culture is one of the best alternatives to ensure the food security of populations faced with the decline in the production of food crops such as millet, sorghum or wheat. To achieve this goal, a better knowledge of the genetic diversity of this culture is more than necessary. Therefore, followed by exploration of accessions collection was made across the country. All the areas visited were geo referenced and a map has been prepared. In total one hundred and fifteen (115) Bambara groundnut accessions were collected within six (6) regions of Niger with fifty (50) locations visited throughout the different growing areas. Fourteen morphotypes numbered Ne-01 to Ne-14 were identified after the collection.

Abstract: (french)
Le voandzou (Vigna subterranea L.), troisième légumineuse alimentaire en Afrique, est la plus importante en termes de production et de consommation après l'arachide (Arachis hypogeae L.) et le niébé (Vigna unguiculata walp.). La valorisation de cette culture représente une des meilleures alternatives pour assurer la sécurité alimentaires des populations face à la baisse de la production des cultures vivrières comme le mil, sorgho ou le blé. Pour atteindre cet objectif, une meilleure connaissance de la diversité génétique de cette culture s'avère plus que nécessaire. C'est ainsi qu'une prospection suivie de collecte des accessions a été effectuée sur l'ensemble du pays. Toutes les zones visitées ont été géo référencées et une carte a été établie. Au total cent quinze (115) accessions de voandzou ont été collectées dans les six (6) régions du Niger avec cinquante (50) localités visitées à travers les différentes zones de culture. Quatorze morphotypes numérotés de Ne-01 à Ne-14 ont été identifiés après la collecte. Suite aux entretiens effectués, le morphotype Ne-01 de couleur jaune est le plus apprécié tant par les producteurs que les consommateurs. Il ressort également que la culture de voandzou se pratique sur des petites superficies aussi bien par les femmes que par les hommes. Le choix de la période de semis est identique aussi bien chez les femmes que chez les hommes. La production est destinée soit à l'autoconsommation ou à la vente en fonction de la quantité récoltée. Les produits chimiques, la cendre, le sel, le natron, des bidons sont couramment utilisés pour la conservation des graines. Plusieurs types des plats sont confectionnés à base de voandzou. En plus, le voandzou présente des valeurs thérapeutiques dans certains milieux paysans.
