Genomic and pedigree-based prediction for leaf, stem, and stripe rust resistance in wheat
The unceasing plant-pathogen arms race and ephemeral nature of some rust resistance genes have been challenging for wheat (Triticum aestivum L.) breeding programs and farmers. Hence, it is important to devise strategies ...
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 ...
A hierarchical bayesian estimation model for multienvironment plant breeding trials in successive years
(Crop Science Society of America (CSSA), 2016)
In agriculture and plant breeding, multienvironment trials over multiple years are conducted to evaluate and predict genotypic performance under different environmental conditions and to analyze, study, and interpret ...
Genetic dissection on rice grain shape by the two-dimensional image analysis in one japonica × indica population consisting of recombinant inbred lines
Two-dimensional (2D) digital image analysis is efficient for investigating the rice grain shape characters in large genetic and breeding populations. In this study, we used 2D image analysis to investigate seven characters, ...
Inclusive composite interval mapping of QTL by environment interactions in biparental populations
(Public Library of Science, 2015)
Identification of environment-specific QTL and stable QTL having consistent genetic effects across a wide range of environments is of great importance in plant breeding. Inclusive Composite Interval Mapping (ICIM) has been ...
Initiating maize pre-breeding programs using genomic selection to harness polygenic variation from landrace populations
(BioMed Central, 2016)
Background: The limited genetic diversity of elite maize germplasms raises concerns about the potential to breed for new challenges. Initiatives have been formed over the years to identify and utilize useful diversity from ...
The development of quality control genotyping approaches: a case study using elite maize lines
(Public Library of Science, 2016)
Quality control (QC) of germplasmidentity and purity is a critical component of breeding and conservation activities. SNP genotyping technologies and increased availability of markers provide the opportunity to employ ...
Molecular characterization of CIMMYT maize inbred lines with genotyping-by-sequencing SNPs
CIMMYT maize inbred lines (CMLs) have been widely used all over the world and have contributed greatly to both tropical and temperate maize improvement. Genetic diversity and population structure of the current CML collection ...
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 ...
Genomic dissection of leaf angle in maize (Zea mays L.) using a four-way cross mapping population
(Public Library of Science, 2015)
Increasing grain yield by the selection for optimal plant architecture has been the key focus in modern maize breeding. As a result, leaf angle, an important determinant of plant architecture, has been significantly improved ...
