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 ...
Toward a cost-effective fingerprinting methodology to distinguish maize open-pollinated varieties
In Africa, many smallholder farmers grow openpollinated maize (Zea mays L.) varieties (OPVs), which allow seed recycling and outyield traditional unimproved landraces. Seeds of productive OPVs are provided to farmers, often ...
Statistical properties of QTL linkage mapping in biparental genetic populations
Quantitative trait gene or locus (QTL) mapping is routinely used in genetic analysis of complex traits. Especially in practical breeding programs, questions remain such as how large a population and what level of marker ...
Characterization of maize germplasm grown in Eastern and Southern Africa : results of the 2001 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, ...
Identification of drought, heat, and combined drought and heat tolerant donors in maize
Low maize (Zea maysL.) yields and the impacts of climate change on maize production highlight the need to improve yields in eastern and southern Africa. Climate projections suggest higher temperatures within drought-prone ...
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 ...
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 ...
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 ...
Consumer acceptability of yellow maize products in Zimbabwe
This study analyzes consumers’ awareness of and attitudes towards yellow maize products in Zimbabwe and suggests intervention strategies that will ensure increased production and consumption of the crop, which is ...
