Identification of drought, heat, and combined drought and heat tolerant donors in maize
(Crop Science Society of America (CSSA), 2013)
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 ...

Grain yield and stability of white early maize hybrids in the highland valleys of Mexico
(Crop Science Society of America (CSSA), 2017)
There is great interest in Mexico in reducing imports of grain and becoming self-sufficient in cereal production. Identifying high-yielding and stable maize (Zea mays L.) hybrids from different research institutions could ...

Gains in maize genetic improvement in Eastern and Southern Africa: I. CIMMYT hybrid breeding pipeline
(Crop Science Society of America (CSSA), 2017)
Monitoring of genetic gain in crop genetic improvement programs is necessary to measure the efficiency of the program. Periodic measurement of genetic gain also allows the efficiency of new technologies incorporated into ...

Gains in maize genetic improvement in Eastern and Southern Africa: II. CIMMYT open-pollinated variety breeding pipeline
(Crop Science Society of America (CSSA), 2017)
Open-pollinated varieties (OP Vs) still represent a significant proportion of the maize (Zea mays L.) seed system in many countries of sub- Saharan Africa. The International Maize and Wheat Improvement Centre (CIMMYT) has ...

Genomic prediction in a large African maize population
(Crop Science Society of America (CSSA), 2017)
Genomic prediction (GP) combines genomewide marker data with phenotypic data in a training population to predict the genomic estimated breeding values of untested individuals in a relevant testing population. Our objective ...
Article
Heterosis and combining ability among CIMMYT's mid-altitude early to intermediate maturing maize (Zea mays L.) populations
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2009)
Maize is an important food crop in sub-Saharan Africa. There is an increasing demand for early maturing maize cultivars even though long-season maize cultivars yield more than early maturing cultivars under favourable ...
Article
Effects of S1 recurrent selection for provitamin A carotenoid content for three open-pollinated maize cultivars
(Crop Science Society of America (CSSA), 2014)
Maize (Zea mays L.) cultivars with increased concentrations of provitamin A (proVA) carotenoids can improve the health of millions of consumers who are vitamin A deficient and rely on maize as a staple food. Three ...
Article
Use of hyperspectral image data outperforms vegetation indices in prediction of maize yield
(Crop Science Society of America (CSSA), 2017)
Hyperspectral cameras can provide reflectance data at hundreds of wavelengths. This information can be used to derive vegetation indices (VIs) that are correlated with agronomic and physiological traits. However, the data ...
Article
Improving maize grain yield under drought stress and non-stress environments in Sub-Saharan Africa using marker-assisted recurrent selection
(Crop Science Society of America (CSSA), 2016)
In marker-assisted recurrent selection (MARS), a subset of molecular markers significantly associated with target traits of interest are used to predict the breeding value of individual plants, followed by rapid recombination ...

Caracterización de razas cubanas de maíz (Zea mays l.) Mediante marcadores agromorfológicos en la colección nacional del cultivo
(Ediciones INCA, 2009)
Cuban maize (Zea mays L.) races constitute a potential of high genetic value for Cuba and the Caribbean region. This work was aimed at characterizing Cuban races by means of agro-morphological markers in the national crop ...
