Biotic constraints (insects, diseases, parasitic weeds) and abiotic stresses (drought) are widespread and pose a constant threat to maize production worldwide. Tropical environments provide the greatest opportunity for evolution of insects and diseases because of the favourable year- round climat...

Combining ability of tropical maize germplasm in West Africa; I: open pollinated varieties
Grain yield of maize (Zea mays L.) in the tropics are generally low and information on combining ability among tropical maize inbred lines has not been reported for West Africa. This study was conducted to estimate combining abilities of maize inbred lines developed for West Africa. Crosses obtai...
