Badu-Apraku, B.Yallou, C.Oyekunle, M.Akinwale, R.Aweke, G.Kamara, A.[Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments]Consistency of performance of early-maturing maize cultivars in Striga infested and Striga-free environments

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...


Badu-Apraku, B.Fakorede, M.A.B.Menkir, A.Kamara, A.Y.Akanvou, L.Chabi, Y.[Response of early maturing maize to multiplestresses in the Guinea savanna of West and Central Africa]Response of early maturing maize to multiplestresses in the Guinea savanna of West and Central Africa

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...


Silberg, T.R.Richardson, R.B.Lopez, M.C.[Maize farmer preferences for intercropping systems to reduce Striga in Malawi]Maize farmer preferences for intercropping systems to reduce Striga in Malawi

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...


Akaogu, I.C.Badu‐Apraku, B.Tongoona, P.B.Ceballos, H.Gracen, V.Offei, S.K.Dzidzienyo, D.[Inheritance of Striga hermonthica adaptive traits in an earlymaturing white maize inbred line containing resistance genes from Zea diploperennis]Inheritance of Striga hermonthica adaptive traits in an earlymaturing white maize inbred line containing resistance genes from Zea diploperennis

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...


Badu-Apraku, B.[Genetic variances and correlations in an early tropical white maize population after three cycles of recurrent selection for Striga resistance]Genetic variances and correlations in an early tropical white maize population after three cycles of recurrent selection for Striga resistance

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...


Ellis-Jones, J.Schulz, S.Douthwaite, BoruHussaini, M.A.Oyewole, B.D.Olanrewaju, A.S.White, R.[An assessment of integrated Striga hermonthica control and early adoption by farmers in northern Nigeria]An assessment of integrated Striga hermonthica control and early adoption by farmers in northern Nigeria

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...


Mutinda, S.M.Masanga, J.Mutuku, J.M.Runo, S.Alakonya, A.E.[KSTP 94, an open-pollinated maize variety has postattachment resistance to purple witchweed (Striga hermonthica)]KSTP 94, an open-pollinated maize variety has postattachment resistance to purple witchweed (Striga hermonthica)

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...


Badu-Apraku, B.Akinwale, R.[Cultivar evaluation and trait analysis of tropical early maturing maize under Strigainfested and Strigafree environments]Cultivar evaluation and trait analysis of tropical early maturing maize under Strigainfested and Strigafree environments

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...


Badu-Apraku, B.Oyekunle, M.Akinwale, R.O.Lum, A.F.[Combining ability of earlymaturing white maize inbreds under stress and nonstress environments]Combining ability of earlymaturing white maize inbreds under stress and nonstress environments

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...


Kamara, A.Y.Ekeleme, F.Omoigui, L.O.Menkir, A.Chikoye, D.Dugje, I.Y.[Response of exotic sorghum (Sorghum bicolor [L.] Moench) cultivars to planting date under natural infestation of Striga hermonthica (Del) Benth. in the Sudan savanna zone of northeast Nigeria]Response of exotic sorghum (Sorghum bicolor [L.] Moench) cultivars to planting date under natural infestation of Striga hermonthica (Del) Benth. in the Sudan savanna zone of northeast Nigeria
