Weather risk : how does it change the yield benefits of nitrogen fertilizer and improved maize varieties in sub‐Saharan Africa?
The purpose of this research was to explore how weather risk affects the value of nitrogen fertilizer use and improved seed variety adoption to sub‐Saharan African (SSA) maize farmers. It contributes to the literature by ...
CIMMYT Maize International Testing Program 1983 : final report
The 1983 Final Report of the International Maize Testing Program includes trial summaries of data received from February 16 to December 15, 1984. Data from 1983 trials received after December 16, 1984 will be in cluded as ...
Marker-assisted breeding of improved maternal haploid inducers in maize for the tropical/subtropical regions
For efficient production of doubled haploid (DH) lines in maize, maternal haploid inducer lines with high haploid induction rate (HIR) and good adaptation to the target environments is an important requirement. In this ...
High-throughput method for ear phenotyping and kernel weight estimation in maize using ear digital imaging
(BioMed Central, 2018)
Background: Grain yield, ear and kernel attributes can assist to understand the performance of maize plant under different environmental conditions and can be used in the variety development process to address farmer's ...
Methodological approach for predicting and mapping the phenological adaptation of tropical maize (Zea mays L.) using multi-environment trials
(BioMed Central, 2018)
Background: The phenological development of the maize crop from emergence through flowering to maturity, usually expressed as a rate (i.e. 1/duration), is largely controlled by temperature in the tropics. Maize plant ...
Hybrids performance of doubled haploid lines derived from 10 tropical bi-parental maize populations evaluated in contrasting environments in Kenya
(Academic Journals, 2017)
The doubled haploid (DH) technology enables maize breeders to develop a large number of homozygous lines rapidly and test them in hybrid combinations early in the breeding cycle. The objectives of this study were to evaluate ...

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 ...
Exploration of farmers' preferences and perceptions of maize varieties: implications on development and adoption of quality protein maize (QPM) varieties in Zimbabwe
(Canadian Center of Science and Education, 2014)
Quality protein maize (QPM) technology is relatively new in Zimbabwe and farmer awareness of QPM was low. Participation of smallholder farmers in the development of QPM breeding objectives and dissemination strategies was ...
