Characterization of maize germplasm grown in Eastern and Southern Africa : results of the 2004 regional trials coordinated by CIMMYT
The Summary Tables present grain yields averaged across sites with significant differences between entries, for each of the five to six environments. Data on agronomic performance such as anthesis date, plant and ear height, ...
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 ...
Doubled haploids in tropical maize: I. Effects of inducers and source germplasm on in vivo haploid induction rates
The adoption of the doubled haploid (DH) technology in tropical maize (Zea mays L.) breeding programs is lagging behind that of temperate programs due to a lack of tropical haploid inducers and reliable information on the ...
Efficiency of managed-stress screening of elite maize hybrids under drought and low-N for yield under rainfed conditions in Southern Africa
Maize (Zea mays L.) yields in southern Africa are low, due largely to drought and low-N stress. Selection of stress-tolerant genotypes by CIMMYT is conducted indirectly under managed stress conditions, although the selection ...
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 ...
Potential impact of investments in drought tolerant maize in Africa
The study evaluates the potential impacts of the Drought Tolerant Maize for Africa (DTMA) project run by CIMMYT and the International Institute for Tropical Agriculture (IITA) in 13 countries of eastern, southern and West ...
