The parasitic weeds, Alectra vogelii Benth., and Striga gesnerioides (Wild.) Vatke, have become major yield-reducing factors in cowpea. Currently, Striga is more prevalent in the Sudan savanna and Sahelian regions and Alectra in the northern Guinea savanna and southern Sudan savanna regions of We...
Two parasitic flowering plants, Striga gesnerioides (Wild.) Vatke and Alectra vogelii (Benth.), cause substantial yield reduction in cowpea in the dry savannas of sub-Saharan Africa. Alectra is more prevalent in the northern Guinea savanna and southern Sudan savanna of West Africa, as well as in ...

Breeding cowpea varieties for resistance to Striga gesnerioides and Alectra vogelii
A number of recent studies have added further information on the genetics of important traits in cowpea. These include inheritance of qualitative traits such as plant pigmentation; flower color; seed color; seed coat texture; resistance to rust, scab, smut, nematode, severe mosaic virus, Striga, ...
The average productivity of cowpea in the existing traditional systems is low due to a complex of biotic
and abiotic stresses. The biotic factors include insect pests, parasitic plants, and viral, fungal and
bacterial diseases. Concerted efforts are being made to develop improved cowpea varieties...

Striga gesnerioides is a serious parasite of cowpea (Vigna unguiculata) on the Abomey plateau of southern Bénin. S. gesnerioides in southern Bénin has been characterized as a race that is different from those found in the dry savanna of West Africa. IITA breeding line IT93KZ-4-5-6-1-5 was used in...
