A field study was conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semideterminate cowpea [Vigna unguiculata (L.) Walp.] genotypes developed in the Nigerian Sudan savannas in 1974 to 2004. Resul...

The parasitic weed Striga gesnerioides (Willd) Vatke is one of the most important constraints to cowpea production in the dry savanna. Yield losses due to S. gesnerioides range from 83 to 100%. No single method however seems to be fully adequate in the control of this parasite. One practice, host...

Cowpea flower bud thrips causes about 80% yield losses in cowpea. Host plant resistance is the most easy and durable solution to the damaging effects caused by this insect. However, resistance to thrips is quantitatively inherited, thus less amenable through conventional breeding. The objective o...

Autor: Muranaka S Fatokun, C.A. Boukar, O.

Parasitic weed, Striga gesnerioides is a major constraint to cowpea [Vigna unguiculata (L.) Walp.] productivity in West and Central Africa. Efforts are being made to identify major genes that determine the race specific resistances to S. gesnerioides in cowpea and to develop resistant varieties w...

The Crop Ontology (CO, http://www.cropontology.org/) is a resource of the Integrated Breeding Platform (IBP, http://integratedbreeding.net/) providing breeders with crop specific terms for fieldbook edition and data annotation. Until Mai 2015, a plant phenotype was annotated with 3 CO identifiers...

The study reveals the stakes of the triple baggingmethod, assesses farmer perception about thistechnology and identifies the factors determiningtheir perception. One of the most limiting factors ofcowpea production is the storage. To solve thisproblem, Purdue University Improved CowpeaStorage Pro...

The stay-green phenomenon is a key plant trait with wide usage in managing crop production under limited water conditions. This trait enhances delayed senescence, biomass, and grain yield under drought stress. In this study we sought to identify QTLs in cowpea (Vigna unguiculata) consistent acros...

Cowpea is one of the most important grain legumes in sub-Saharan Africa (SSA). It provides strong support to the livelihood of small-scale farmers through its contributions to their nutritional security, income generation and soil fertility enhancement. Worldwide about 6.5 million metric tons of ...
