The magnitude of genetic expression and associations among traits are important for the prediction of response to selection in diverse environments and provide the basis for planning and evaluating breeding programs. In this regard, a cross classification mating design was used to produce hybrid ...

The moist savannas of West and Central Africa have great potential for maize grain production due to high levels of radiation and reduced incidence of pests and diseases. However, soils in this zone are generally low in organic matter and cation exchange capacity in addition to land use intensifi...

The success of most crop improvement programs largely depends upon the genetic variability and the heritability of desirable traits. The magnitude and type of genetic variability help the breeder to determine the selection criteria and breeding schemes to be used for improvement purposes. A scree...

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...
