Identification of in vivo induced maternal haploids in maize using seedling traits
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 ...
Performance and grain yield stability of maize populations developed using marker-assisted recurrent selection and pedigree selection procedures
A marker-assisted recurrent selection (MARS) program was undertaken in sub-Saharan Africa to improve grain yield under drought-stress in 10 biparental tropical maize populations. The objectives of the present study were ...
Characterization of a global germplasm collection and its potential utilization for analysis of complex quantitative traits in maize
Association mapping is a powerful approach for exploring the molecular basis of phenotypic variations in plants. A maize (Zea mays L.) association mapping panel including 527 inbred lines with tropical, subtropical and ...
Genetic diversity and population structure of native maize populations in Latin America and the Caribbean
(Public Library of Science, 2017)
This study describes the genetic diversity and population structure of 194 native maize populations from 23 countries of Latin America and the Caribbean. The germplasm, representing 131 distinct landraces, was genetically ...
Analysis of genetic variability for kernel carotenoid concentration in selected maize inbred lines
A selected set of 24 maize (Zea mays L.) inbred lines were analyzed to study genetic variability for total kernel carotenoid concentration. The results revealed significant genetic variation among the selected maize inbreds ...
Dissection of a major QTL qhir1 conferring maternal haploidinduction ability in maize
(Springer-Verlag Heidelberg, 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 ...
Grain yield performance and flowering synchrony of CIMMYT’s tropical maize (Zea mays L.) parental inbred lines and single crosses
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 ...
Analysis of genetic diversity in the North Eastern Himalayan (NEH) maize landraces of India using microsatellite markers
Population DNA fingerprinting of 48 selected North Eastern Himalayan (NEH) landrace accessions was undertaken using 41 polymorphic fluorescent dye-labelled microsatellite/Simple Sequence Repeat (SSR) markers, using a DNA ...
Molecular characterization of CIMMYT maize inbred lines with genotyping-bysequencing SNPs
Key message Molecular characterization information on genetic diversity, population structure and genetic relationships provided by this research will help maize breeders to better understand how to utilize the current CML ...
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 ...
