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 ...

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 ...

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 ...

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 ...

QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance
(Springer, 2012)
Despite numerous published reports of quantitative trait loci (QTL) for drought-related traits, practical applications of such QTL in maize improvement are scarce. Identifying QTL of sizeable effects that express more or ...
