Maize (Zea mays L.) is the most important staple crop in West and Central Africa (WCA), but its production is severely constrained by low soil nitrogen (low N). Fifty-six extra-early open-pollinated maize cultivars developed during three breeding eras, 1995–2000, 2001–2006 and 2007–2012, were eva...

The aim of the study was to identify entomological determinants of increased malaria transmission in the vicinity of the Koka reservoir in Central Ethiopia. Larval and adult mosquitoes were collected between August 2006 and December 2007 in villages close to (<1 km) and farther away from (>6 km) ...

Cassava is a globally important food security and industrial crop produced for food, feed, starch and biofuel. Cassava is drought-tolerant and can grow in poor soils. Roots can be stored in the ground for long periods as part of intact growing plants, allowing flexible harvest times for poor farm...

Sweetpotato breeding requires at least 5 years to obtain an advanced breeding clone for further testing with the goal of cultivar release. An accelerated breeding scheme (ABS) can be feasible if the genotype × year interaction is low. The objectives of the present study were to describe an ABS fo...

Cassava (Manihot esculenta Crantz) is a clonally propagated staple food crop in the tropics. Genomic selection (GS) has been implemented at three breeding institutions in Africa to reduce cycle times. Initial studies provided promising estimates of predictive abilities. Here, we expand on previou...

The future security of the supply of rice for food in Africa depends on improving the level of local production to achieve self-sufficiency. In order to cope with the existing gap between production and actual demand, combining a high level of rice blast tolerance and a high-yield potential is ne...

A working collection of yam (Dioscoreaspp.) comprising 53 landraces and seven improved cultivars of four species (D. alata L., D. cayenensis Lam., D. dumetorum (Kunth) and D. rotundata Poir.) was evaluated for phenotypic and genetic diversity. The evaluation involved field assessment of 24 morpho...

The parasitic flowering plants Striga gesnerioides (Willd.) Vatke and Alectra vogelii (Benth.) are formidable cowpea production constraints in the West and Central African savanna. The two parasites cause substantial yield reduction in cowpea in the dry savannas. A field study was conducted to sc...
