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 ...
