The parasitic flowering plants, Striga gesnerioides (wild.) Vatke and Alectra vogelii (Benth.), cause substantial yield reduction in cowpea in the dry savcannas of sub-Saharan Africa. Alectra is more prevalent in the Northern Guinea savanna and Southern Sudan Savanna of West Africa, as well as in...
The parasitic weeds Striga gesnerioides (Willd.) Vatke and Alectra vogelli (Benth.) cause considerable demage to cowpea [ Vigna unguiculata (L.) Walp] in the semiarid regions of Africa. Systematic screening has revealed few cowpea varieties to be resistant. Of these, B 301 is resistant to both st...
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 ...
