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 ...

Adoption of drought tolerant maize varieties under rainfall stress in Malawi
(John Wiley and Sons, 2019)
We examine adoption of drought tolerant (DT) maize varieties using a four‐round panel dataset from six districts in Malawi. There is an increase in adoption of DT maize from 3% in 2006 to 43% in 2015 in our data. We focus ...
Article
Multi‐site bundling of drought tolerant maize varieties and index insurance
(Wiley, 2020)
Drought Tolerant Maize Varieties (DTMV) and Rainfall Index Insurance (RII) are potential complements, though with limited empirical basis. We employ a multivariate spatial framework to investigate the potential for bundling ...

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 ...
Article
Impact of adoption of drought-tolerant maize varieties on total maize production in south Eastern Zimbabwe
(Taylor & Francis, 2019)
Drought is a huge limiting factor in maize production, mainly in the rain-fed agriculture of sub-Saharan Africa. In response to this threat, drought-tolerant (DT) maize varieties have been developed with an aim to ensure ...
Article
Potential benefits of drought and heat tolerance for adapting maize to climate change in tropical environments
(Elsevier, 2018)
Climate change and population growth pose great challenges to the food security of the millions of people who grow maize in the already fragile agricultural systems in tropical environments. There is an urgent need for ...
Article
Yield gains and associated changes in an early yellow bi-parental maize population following genomic selection for Striga resistance and drought tolerance
(BioMed Central, 2019)
Background: Maize yield potential is rarely maximized in sub-Saharan Africa (SSA) due to the devastating effects of drought stress and Striga hermonthica parasitism. This study was conducted to determine the gains in grain ...
Article
Evaluation of CIMMYT drought tolerant maize germplasm for resistance to weevil (Sitophilus zeamais Motschulky) damage
(Academic Journals, 2015)
This study was carried out to evaluate and assess the phenotypic correlation between the primary and secondary weevil resistant traits of 20 drought tolerant (DT) late maturing maize hybrids (LHYB) to weevil (Sitophilus ...
Article
Use of genomic estimated breeding values results in rapid genetic gains for drought tolerance in maize
(Crop Science Society of America, 2017)
More than 80% of the 19 million ha of maize (Zea mays L.) in tropical Asia is rainfed and prone to drought. The breeding methods for improving drought tolerance (DT), including genomic selection (GS), are geared to increase ...
Article
Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection
(Frontiers, 2017)
The objective of marker assisted recurrent selection (MARS) is to increase the frequency of favorable marker alleles in a population before inbred line extraction. This approach was used to improve drought tolerance and ...
