“…Striga gesnerioides is a major limitation to cowpea production in Africa (Timko et al, 2007b), causing considerable yield losses (Aggarwal and Ouédraogo, 1989). The extent of the damage in cowpea due to S. gesnerioides could be up to 70% depending on the extent of damage and level of infestation (Alonge et al, 2004). On susceptible cultivars, yield losses can reach up to 100% when S. gesnerioides population is over 10 emerged shoots per plant (Kamara et al, 2008).…”

Parasitic weed Striga gesnerioides (Willd.) is one of the major constraints of cowpea production. Hostplant resistance seems to be efficient and economical in controlling the pest. The objectives of this study were to evaluate recombinant inbred lines developed between IT97K 499-35 (Striga resistant parent,) and Sanzi (susceptible parent), by Single Seed Descent (SSD), for Striga resistance in Northern Ghana. The study also evaluated the promising Striga gesnerioides resistant lines and susceptible checks for yield loss due to Striga infestation. The studies involved a field and pot screening under artificial inoculation. Twenty-seven (27) recombinant inbred lines (RILs) out of the 251 RILs screened were resistant to Striga gesnerioides. The percentage reduction in the grain yield and dry biomass were lower in the resistant RILs (0.55 to 3.08% and 1.11 to 7.7%, respectively) than the susceptible ones (28.45 to 58.88% and 47.29 to 61.71%, respectively). The negative effect of Striga infestation on cowpea grain yield and dry biomass can then be reduced when resistant genotypes are used.

“…Some of the most destructive threats to cowpea are parasitic weeds. These parasitic weeds, such as Striga gesnerioides (Timko et al, 2007b), can cause significant losses in crop yield (Alonge et al, 2005a; In that time, extensive genomic work on soybean was being done. According to a review by Chan et al, (2012), such work spanned more than ten years, and started with the creation of physical and linkage maps using such methods as combining populations (Cregan et al 1999;Marek et al 2001;Song et al 2004;Choi et al 2007;Hyten et al 2010a), genomic BAC and BIBAC libraries (Wu et al , 2008Shoemaker et al 2008), and integrating information from available maps (Hyten et al 2010b).…”

“…Cowpea crop yields are reduced by many stresses, especially parasitic weeds (Timko et al, 2007a;Alonge et al, 2005a;Alonge et al, 2005b;. Despite its importance, however, cowpea has not been researched as much as other plants .…”

“…But among the worst threats to cowpea yield, biotic or abiotic, are parasitic weeds. Weeds such as Striga gesnerioides (Timko et al, 2007) can reduce crop yields significantly (Alonge et al, 2005a;Alonge et al, 2005b), sometimes up to 100% yield loss . Yet despite the importance of cowpea and the myriad threats to cowpea that exist, cowpea has not been studied as well as other crop plants .…”

“…Parasitic plants such as Striga gesnerioides (witch weeds) are particularly devastating (Timko et al, 2007), reducing crop yields significantly (Alonge et al, 2005a;Alonge et al, 2005b), potentially causing 100% yield loss . Despite its importance, cowpea has been under--studied compared to other crop plants .…”

Cowpea, Vigna unguiculata (L.) Walp., is an important food and forage legume in the semi--arid tropics. Among the greatest constraints of crop yield in cowpea are root--parasitic angiosperms such as Striga gesnerioides, which drain the cowpea plant of much needed nutrients. Thus, improved resistance to parasitic weeds, among other stresses, is among the most important goals of cowpea breeding programs. Plant
