Improving maize productivity in the savannas of West Africa will depend on improving soil fertility and ensuring the efficient use of inputs and the relevant maize varieties tolerant to low nitrogen (N) that have been developed for this region. Several cycles of full-sib family selection that com...

Crosses were made and cv. and lines selected to combine the existing resistance to Xanthomonas campestris pv. phaseoli with adaptation to the tropics and to determine new sources of resistance. Crosses were made between adapted lines and sources of resistance, some with Great Northern genes. The ...
