Cowpea [ Vigna unguiculata (L.) Walp.] is an important source of food and fodder in the dry savanna of West Africa. Traditional cowpea varieties are photosensitive (PS), growing profusely when planted in long days and they flower when days become shorter. However, we have observed that all PS cow...

Le niebe [Vigna unguiculata (L.) Walp.] est une importante source de nutriture et de fourage dans la savanne seche de l' Afrique de l'Ouest. Les varietes traditionnelles de vigna sont photosensibles, poussant exuberamment quand elles sont plantees en jours longs et elles flourissent quand les jou...

Cowpea, an indigenous crop to sub-Saharan Africa, is found mainly in the dry savanna regions along with cereals such as millets and sorghum. Cowpea is grown primarily for human consumption of the grains, which are rich in protein, carbohydrates and contain some minerals. The development and deplo...

Cowpea (Vigna unguiculata [L.] Walp.) is the most important grain legume in the dry savannas of West Africa, however grain and fodder yields are low (averaging 25 to 300 kg and 450 to 800 kg grain and fodder/ha, respectively) due to biotic and abiotic constraints. Improved varieties and cropping ...

A partial sterile line of cowpea (Vigna unguiculata (L.) Walp.) resulting from spontaneous mutation was characterised. Plants were classified based on plant morphology, pollen viability and pod set. Partial sterile plants remained green past usual maturity and had thick leathery leaves with a few...

Une lignée partielle de niébé (Vigna unguiculata (L.) Walp.) Résultant d'une mutation spontanée a été caractérisée. Les plantes ont été classées en fonction de la morphologie de la plante, de la viabilité du pollen et de l'ensemble des gousses. Les plantes stériles partielles sont restées vertes ...
