Development, maintenance and seed multiplication of open-pollinated maize varieties
The procedures for the production of maize hybrid seed and maintenance of parental lines are well documented. However, not much has been written on the development, maintenance, and multiplication of improved open pollinated ...
Insect resistant maize recent advances and utilization: proceedings of an international symposium held at (CIMMYT)
This publication reports advances in world wide research on the mechanisms and bases of insect resistance in maize; the genetics of resistance; on the biotechnological manipulation of resistance; on techniques for the mass ...
Cereal crop productivity in developing countries: past trends and future prospects
This paper synthesizes the evidence on cereal crop poductivity in developing countries over the past 30 years and looks at future prospects for productivity in growth. For more than three decades we have witnessed the ...
Breeding for drought and nitrogen stress tolerance in maize: from theory to practice
Targeted initially for maize breeders in sub-Saharan Africa, the content is based on a successful approach developed at CIMMYT for improving the tolerance of maize to drought and low nitrogen stress. Intended as a supplement ...

Desarrollo, mantenimiento y multiplicación de semilla de variedades de polinización libre
Los procedimientos para la producción de semilla de híbridos de maíz y el mantenimiento de líneas progenitoras están bien documentados. Sin embargo, poco se ha escrito acerca del desarrollo, mantenimiento y multiplicación ...
Efficiency of high-nitrogen selection environments for improving maize for low-nitrogen target environments
Most maize (Zea mays L.) in the tropics is grown under low-nitrogen (N) conditions, raising the need to assess efficient breeding strategies for such conditions. This study assesses the value of low-N vs. high-N selection ...
Selection for drought tolerance increases maize yields across a range of nitrogen levels
It is not known whether selection for improved tolerance to a specific abiotic stress leads to correlated changes in performance under other stresses. Drought and N deficiency are important constraints to production in the ...
Inbred line evaluation nurseries and their role in maize breeding at CIMMYT
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Valorizzazione qualitativa dei cereali, 1999)
CIMMYT initiated its hybrid maize (Zea mays) research programme in 1985 in response to the growing needs of the national programmes for hybrid-oriented source germplasm. Since 1991 CIMMYT has released a total of 424 inbreds ...
