Article
Factors affecting genomic selection revealed by empirical evidence in maize
(Elsevier, 2018)
Genomic selection (GS) as a promising molecular breeding strategy has been widely implemented and evaluated for plant breeding, because it has remarkable superiority in enhancing genetic gain, reducing breeding time and ...
Article
Genome-wide association mapping and genomic prediction analyses reveal the genetic architecture of grain yield and flowering time under drought and heat stress conditions in maize
(Blackwell Verlag, 2019)
Drought stress (DS) is a major constraint to maize yield production. Heat stress (HS) alone and in combination with DS are likely to become the increasing constraints. Association mapping and genomic prediction (GP) analyses ...
Article
Dissection of a major QTL qhir1 conferring maternal haploid induction ability in maize
(Springer, 2017)
In vivo haploid induction in maize can be triggered in high frequencies by pollination with special genetic stocks called haploid inducers. Several genetic studies with segregating populations from non-inducer x inducer ...
Article
A novel remote sensing approach for prediction of maize yield under different conditions of nitrogen fertilization
(Frontiers, 2016)
Maize crop production is constrained worldwide by nitrogen (N) availability and particularly in poor tropical and subtropical soils. The development of affordable high-throughput crop monitoring and phenotyping techniques ...
Article
Identification of donors for low-nitrogen stress with maize lethal necrosis (MLN) tolerance for maize breeding in sub-Saharan Africa
(Springer, 2019)
After drought, a major challenge to smallholder farmers in sub-Saharan Africa is low-fertility soils with poor nitrogen (N)-supplying capacity. Many challenges in this region need to be overcome to create a viable fertilizer ...
Article
Genetic analysis of tropical maize inbred lines for resistance to maize lethal necrosis disease
(Springer, 2017)
Maize lethal necrosis (MLN) disease is a recent outbreak in eastern Africa and has emerged as a significant threat to maize production in the region. The disease is caused by the co-infection of Maize chlorotic mottle virus ...
Article
Grain yield performance and flowering synchrony of CIMMYT’s tropical maize (Zea mays L.) parental inbred lines and single crosses
(Springer, 2016)
Maize production constraints in sub-Saharan Africa (SSA) are being addressed by CIMMYT and partners through an array of projects, focusing on developing and evaluating parental inbred lines and single-crosses as well as ...
Article
Identification of in vivo induced maternal haploids in maize using seedling traits
(Springer, 2017)
In vivo haploid induction in high frequency followed by efficient identification of haploids are important components of deriving completely homozygous doubled haploid (DH) lines in maize. Several genetic marker systems ...
Article
Genome-wide association study to identify genomic regions influencing spontaneous fertility in maize haploids
(Springer, 2019)
Efficient production and use of doubled haploid lines can greatly accelerate genetic gains in maize breeding programs. One of the critical steps in standard doubled haploid line production is doubling the haploid genome ...
