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 ...
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 ...
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 ...
In situ conservation of crops and their relatives: a review of current status and prospects for wheat and maize
This paper reviews the current status and prospects for in situ conservation of maize and wheat and their relatives. The caricature of in situ conservation-that it imposes cultural stasis and isolation on marginal ...
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 ...
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 ...
Wheat breeders' perspectives on genetic diversity and germplasm use: Findings from an international survey
Wheat breeders working in national wheat research programmes around the world, and particularly those in developing countries, are concerned that in the future scientific advance may be limited because wheat genetic diversity ...
