Genetic diversity among selected elite CIMMYT maize hybrids in East and Southern Africa
(Crop Science Society of America, 2017)
Genetic gain within the CIMMYT Eastern and Southern Africa (ESA) hybrid maize (Zea mays L.) breeding program from 2000 to 2010 was recently estimated at 0.85 to 2.2% yr−1 under various environmental conditions. Over 100 ...
Article
Molecular mapping across three populations reveals a QTL hotspot region on chromosome 3 for secondary traits associated with drought tolerance in tropical maize
(Springer; Springer Nature, 2014)
Identifying quantitative trait loci (QTL) of sizeable effects that are expressed in diverse genetic backgrounds across contrasting water regimes particularly for secondary traits can significantly complement the conventional ...
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 ...
Article
Discovery and validation of genomic regions associated with resistance to maize lethal necrosis in four biparental populations
(Springer Verlag, 2018)
In sub-Saharan Africa, maize is the key determinant of food security for smallholder farmers. The sudden outbreak of maize lethal necrosis (MLN) disease is seriously threatening the maize production in the region. Understanding ...

Developing and deploying climate-resilient maize varieties in the developing world
(Elsevier, 2018)
In sub-Saharan Africa (SSA) and Asia maize yields remain variable due to climate shocks. Over the past decade extensive progress has been made on the development and delivery of climate-resilient maize. In 2016 over 70 000 ...

Development and validation of red root marker-based haploid inducers that effectively complement R1-nj (Navajo) marker-based in vivo haploid identification in maize
(Crop Science Society of America (CSSA), 2016)
One of the critical limitations for the in vivo production of doubled haploid (DH) lines in maize (Zea mays L.) is the inability to effectively identify haploids in a significant proportion of induction crosses due to the ...
Article
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 ...
Article
Genome-wide association for plant height and flowering time across 15 tropical maize populations under managed drought stress and well-watered conditions in Sub-Saharan Africa
(Crop Science Society of America (CSSA), 2016)
Genotyping breeding materials is now relatively inexpensive but phenotyping costs have remained the same. One method to increase gene mapping power is to use genome-wide genetic markers to combine existing phenotype data ...
Article
Genome‑wide association and genomic prediction of resistance to maize lethal necrosis disease in tropical maize germplasm
(Springer, 2015)
The maize lethal necrosis disease (MLND) caused by synergistic interaction of Maize chlorotic mottle virus and Sugarcane mosaic virus, and has emerged as a serious threat to maize production in eastern Africa since 2011. ...
Article
Molecular characterization of CIMMYT maize inbred lines with genotyping-by-sequencing SNPs
(Springer, 2016)
CIMMYT maize inbred lines (CMLs) have been widely used all over the world and have contributed greatly to both tropical and temperate maize improvement. Genetic diversity and population structure of the current CML collection ...
