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 ...
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 ...
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 ...
Developing drought and low-nitrogen tolerant maize
Proceedings of a symposium hosted at CIMMYT in 1996, this publication describes the incidence and intensity of drought and low nitrogen conditions for maize in the tropics, the physiology of drought tolerance and the ...
