Association mapping for enhancing maize (Zea mays l.) genetic improvement
Association mapping through linkage disequilibrium (LD) analysis is a powerful tool for the dissection of complex agronomic traits and for the identification of alleles that can contribute to the enhancement of a target ...
Performance prediction of F1 hybrids between recombinant inbred lines derived from two elite maize inbred lines
Selection of recombinant inbred lines (RILs) from elite hybrids is a key method in maize breeding especially in developing countries. The RILs are normally derived by repeated self-pollination and selection. In this study, ...
The strategy and potential utilization of temperate germplasm for tropical germplasm improvement: a case study of maize (Zea mays L.)
The organization of maize (Zea mays L.) germplasm into genetically divergent heterotic groups is the foundation of a successful hybrid maize breeding program. In this study, 94 CIMMYT maize lines (CMLs) and 54 United States ...
Comparison of SSRs and SNPs in assessment of genetic relatedness in maize
Advances in high-throughput SNP genotyping and genome sequencing technologies have enabled genome-wide association mapping in dissecting the genetic basis of complex quantitative traits. In this study, 82 SSRs and 884 SNPs ...
Economic impact of maize stem borer (Chilo partellus) attack on livelihood of maize farmers in Pakistan
(Asian Journal of Agriculture and Biology, 2019)
Maize is third important cereal in Pakistan after wheat and rice. The demand of maize is increasing due to poultry and other industries. However the maize crop is faced with number of challenges especially the attack of ...
Estimation of physiological genomic estimated breeding values (PGEBV) combining full hyperspectral and marker data across environments for grain yield under combined heat and drought stress in tropical maize (Zea mays L.)
(Public Library of Science, 2019)
High throughput phenotyping technologies are lagging behind modern marker technology impairing the use of secondary traits to increase genetic gains in plant breeding. We aimed to assess whether the combined use of ...
Genome-wide association study to identify genomic regions influencing spontaneous fertility in maize haploids
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 ...
Conserving and enhancing maize genetic resources as global public goods-A perspective from CIMMYT
The growing demands for food, feed, and bioenergy worldwide will require a 2% per annum increase in global maize (Zea mays L.) production. Maize is one of the most important staple food crops across the developing world ...
