Diagnostic trials were implemented in Kenya, Malawi, Mali, Nigeria and Tanzania, as part of the African Soils Informa...
An expt. to study the background soil effects associated with var. resistance in bean pest populations, virus incidence and yield was carried out at the Centro Internacional de Agricultura Tropical (CIAT), Palmira, Colombia from Jan.-March, 1978. The effect of the treatments and of the var. on Em...
The genetic improvement of drought resistance is essential for stable and adequate crop production in drought-prone areas1. Here we demonstrate that alteration of root system architecture improves drought avoidance through the cloning and characterization of DEEPER ROOTING 1 (DRO1), a rice quanti...
La principal causa de la baja productividad en campo es la sequía, y como la mayoría de métodos para contrarrestarle son costosos e inasequibles para los agricultores de bajos recursos, se ha encontrado que el mejoramiento genético es la opción más económica para incrementar o estabilizar la prod...
