Drought occurrence and striga hermonthica (Del.) Benth infestation are formidable maize (Zea mays L.) production constriants in the savanna zones of West and Central Africa (WCA). The West and Central Africa collaborative Maize Research Network (WECAMAN), in collaboration with the International I...
In southern Africa the repeated cultivation of maize (Zea mays) and climate variability (especially frequent and extended droughts) have created conditions favouring parasitic weed infestation (e.g., Striga asiatica). In the past decade, Striga has reduced maize yields for smallholder farmers (cu...
Striga hermonthica can cause as high as 100% yield loss in maize depending on soil fertility level, type of genotype, severity of infestation and climatic conditions. Understanding the mode of inheritance of Striga resistance in maize is crucial for introgression of resistance genes into tropical...
The magnitude and type of genetic variability are of prime importance to breeders in determining whether or not to improve a breeding population and the method to use. The early maturing population, TZE-W Pop DT STR, has gone through three cycles of S1 recurrent selection for improvement for grai...
Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...
Striga spp. are obligate root hemiparasites that constrain cereal production in sub-Saharan Africa. Although purple witchweed [ Striga hermonthica (Delile) Benth.] and Asiatic witchweed [ Striga asiatica (L.) Kuntze] infect all cereal crops, maize ( Zea mays L.) is particularly vulnerable to thei...
Striga hermonthica is a major constraint to maize (Zea mays L.) production in sub-Saharan Africa. The use of secondary traits that have high heritability and genetic correlation with grain yield can improve the precision with which Striga resistant genotypes are identified. Fifteen early cultivar...
Maize (Zea mays L.) hybrids resistant to Striga hermonthica (Del) Benth and tolerant to drought are vital to the sustainability of productivity of the maize-based farming systems of West and Central Africa (WCA). Thirty-six diallel crosses derived from nine early maturing white maize inbreds were...
Sorghum (Sorghum bicolor [L.] Moench) is one of the most important cereal crops grown in the dry savannas and semi-arid regions of West Africa under rain-fed conditions. Although total sorghum production in Nigeria has increased over the years, the average grain yield on farmers' fields has remai...
