Association analysis for resistance to Striga hermonthica in diverse tropical maize inbred lines
Striga hermonthica is a widespread, destructive parasitic plant that causes substantial yield loss to maize productivity in sub-Saharan Africa. Under severe Striga infestation, yield losses can range from 60 to 100% resulting in abandonment of farmers ...

Estimating genetic gains for tolerance to stress combinations in tropical maize hybrids
Maize is a strategic food crop in sub-Saharan Africa. However, most maize growing tropical savannas particularly in West and Central African experience the occurrence of frequent droughts and Striga infestation, resulting in 30–100% yield losses.

Inheritance of Striga hermonthica adaptive traits in an earlymaturing white maize inbred line containing resistance genes from Zea diploperennis [PDF]
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.

Abstract 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 cultivars were evaluated under Striga -infested

Genetic variation and host-parasite specificity of Striga resistance and tolerance in rice: the need for predictive breeding [PDF]
The parasitic weeds Striga asiatica and Striga hermonthica cause devastating yield losses to upland rice in Africa. Little is known about genetic variation in host resistance and tolerance across rice genotypes, in relation to virulence differences ...

Evaluation of 15 F1 hybrids and six parents obtained from partial diallel crosses was carried out during 2011 rainy season at Institute of Agricultural Research (IAR) Samaru, Zaria Striga infested field and Striga free field (2 environments). Interrelationships of grain yield and its components under Striga infestation revealed that character ear ...

Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions [PDF]
Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. Away from cultivated farmland, wild
