Developing drought- and low N-tolerant maize: proceedings of a symposium, March 25-29, 1996, CIMMYT, El Batan, Mexico
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 ...
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 ...
Effect of source germplasm and season on the in vivo haploid induction rate in tropical maize
For in vivo production of doubled haploid (DH) lines in maize, the rate of haploid induction is of crucial importance. Maternal haploid induction depends primarily on the inducer used as a pollinator. However, the source ...
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 ...
Climate change and food security in the developing world: Potential of maize and wheat research to expand options for adaptation and mitigation
Maize and wheat are two of the most important food crops worldwide. Together with rice, they provide 30% of the food calories to 4.5 billion people in almost 100 developing countries. Predictions suggest that climate change ...
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 ...
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 Valorizzazione qualitativa dei cereali, 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) ...
