Mejoramiento para aumentar la tolerancia a sequía y a deficiencia de nitrógeno en el maíz: de la teoría a la práctica
Este documento, dirigido inicialmente a los mejoradores de maíz en África al sur del Sahara, se basa en un método probado que fue elaborado en el CIMMYT con el fin de mejorar la tolerancia del maíz al estrés por sequía y ...
Relative importance of general combining ability and specific combining ability among tropical maize (Zea mays L.) inbreds under contrasting nitrogen environments
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2008)
Low-N stress is among the major abiotic stresses causing yield reductions in maize grown in the mid-altitude tropical environments of Africa. This study estimates the relative importance of general combining ability (GCA) ...
Potential impact of investments in drought tolerant maize in Africa
The study evaluates the potential impacts of the Drought Tolerant Maize for Africa (DTMA) project run by CIMMYT and the International Institute for Tropical Agriculture (IITA) in 13 countries of eastern, southern and West ...
An analysis of the bottlenecks affecting the production and deployment of maize seed in eastern and Southern Africa
The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide ...
Maize production environments revisited: A GIS-based approach
This publication presents a GIS-based approach for revising the descriptions of global maize production environments, called "mega-environments" (MEs), used by CIMMYT and its partners. A cluster analysis was performed on ...
Characterization of maize germplasm grown in Eastern and Southern Africa: results of the 2004 regional trials coordinated by CIMMYT
The Summary Tables present grain yields averaged across sites with significant differences between entries, for each of the five to six environments. Data on agronomic performance such as anthesis date, plant and ear height, ...
