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 ...
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 ...
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 ...
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 ...
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 ...
Crops that feed the world 6. Past successes and future challenges to the role played by maize in global food security
(Springer Verlag, 2011)
Maize is one of the most important food crops in the world and, together with rice and wheat, provides at least 30% of the food calories to more than 4.5 billion people in 94 developing countries. In parts of Africa and ...
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) ...
Breeding for low input conditions and consequences for participatory plant breeding: examples from tropical maize and wheat
Participatory plant breeding (PPB) has been suggested as an effective alternative to formal plant breeding (FPB) as a breeding strategy for achieving productivity gains under low input conditions. With genetic progress ...
Combining ability, heterosis and genetic diversity in tropical maize (Zea mays L.) under stress and non-stress conditions
Drought and low soil fertility are considered the most important abiotic stresses limiting maize production in sub-Saharan Africa. Knowledge of the combining ability and diversity of inbred lines with tolerance to the two ...
