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...

En varias regiones de Nicaragua, el cultivo de arroz de secano asume un papel importante para la seguridad alimenticia de las familias campesinas, además es fuente de ingresos para éstas. Apartir del 2002, el CIRAD y el CIAT implementan en colaboración en Nicaragua un proyecto de investigación en...

Research on lima beans (Phaseolus lunatus) was conducted regarding adaptation, resistance to common bacterial blight (Xanthomonas phaseoli), resistance to leafhoppers (Empoasca kraemeri), and cyanide concn. in lima bean seed. In adaptation studies 36 climbing lima bean lines were selected from th...

We have sought to test the possibility of detecting regions of the genome under selection through effects on variation at linked neutral genetic markers. Particularly, we investigated three genomic regions identified by mapping in a cross-bred pedigree as harbouring QTL for trypanosomiasis tolera...
