Studies on the Biology of <i>Striga aspera</i> (Scrophulariaceae) in Nigeria
<p>Studies on Striga aspera are few and little information exists on its relationship with the morphologically similar and much studied S. hermonthica. Both species are sympatric in West Africa and if they hybridize, may serve as virulent gene reservoirs for each other.</p> <p>The primary focus of …

Biosystematics and Diversification in the Genus <i>Striga Lour.</i> (Scrophulariaceae) in Africa
<p>Of the 34 taxa of <em>Striga</em> (29 species) that occur in Africa, 25 are endemic. Species diversity differs from region to region. The subtropical zone has 74% of the taxa including 41% endemics. Within this region, the West African part (from Senegal to eastern Nigeria) has 62% of the total …

Nitrogen and genotype effects on assimilate partitioning and resistance to Striga in maize
The parasitic angiosperm Striga (Striga hermonthica Del. Benth) infects tropical cereals causing heavy losses. Investigations were undertaken in western Kenya in 1989 and 1990 to determine if the occurrence of Striga in maize (Zea mays L.) could be mediated by amount, source and timing of N …

Combining ability for yeild of imidazolinone resistant maize inbred lines under artificial and natural striga infestation
Striga hermonthica (Del.) Beth popularly known as witchweed infests cereal crops particularly maize (Zea mays L.) leading to severe reductions in yields, thereby compounding the food insecurity of thousands of households in sub-Saharan Africa region. In Tanzania, maize is grown on about 2 million …

A Bio-Economic Model of Long-Run Striga Control with an Application to Subsistence Farming in Mali
The parasitic weeds belonging to the genus Striga are among the world's most tenacious, prolific and destructive agricultural pests. Crop loss estimates due to Striga infestations can reach 100 percent. Furthermore, the weeds' affinity for low-fertility soils and low rainfall means that those …

Genomics-enabled breeding for sorghum in West Africa
… to develop diagnostic markers for resistance to Striga hermonthica, a weed parasite of grass crops, in which resistance is known to be associated with a deletion of a few genes. Using GBS data, single nucleotide polymorphisms in linkage disequilibrium with the deletion to generate …
