Large-Scale Evaluation of Maize Germplasm for Low-Phosphorus Tolerance
(Public Library of Science, 2015)
Low-phosphorus (LP) stress is a global problem for maize production and has been exacerbated by breeding activities that have reduced the genetic diversity of maize. Although LP tolerance in maize has been previously ...
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 ...
Background on the development of the : global strategy for the Ex situ conservation and utilization of maize germplasm
(Global Crop Diversity Trust; CIMMYT, 2007)
Effectiveness of selection at CIMMYT's main maize breeding sites in Mexico for performance at sites in Africa and vice versa
The exchange of elite breeding materials across regions is an important way in which multinational maize breeding programmes access new genetic variation, improve efficiency and reduce costs. Our objectives were to examine ...
Genetic variability and genotype x environment interactions for kernel iron and zinc concentrations in maize (Zea mays) genotypes
Micronutrient enrichment in the major staple food crops is an important breeding goal in view of the extensive problem of 'hidden hunger' caused by micronutrient malnutrition. Kernel iron (Fe) and zinc (Zn) concentrations ...
Formation of heterotic groups and understanding genetic effects in a provitamin a biofortified maize breeding program
Developing biofortified maize cultivars is a viable approach to combat the widespread problem of vitamin A deficiency among people for whom maize is a staple food. To enhance CIMMYT's provitamin A maize breeding efforts, ...
Independent introductions and admixtures have contributed to adaptation of European maize and its American counterparts
(Public Library of Science, 2017)
Through the local selection of landraces, humans have guided the adaptation of crops to a vast range of climatic and ecological conditions. This is particularly true of maize, which was domesticated in a restricted area ...
Genetic gains in yield and yield related traits under drought stress and favorable environments in a maize population improved using marker assisted recurrent selection
The objective of marker assisted recurrent selection (MARS) is to increase the frequency of favorable marker alleles in a population before inbred line extraction. This approach was used to improve drought tolerance and ...
The private and public characteristics of maize land races and the area allocation decisions of farmers in a center of crop diversity
This study uses an approach derived from models of the private and public characteristics of goods to illustrate (1) the overriding importance of variety attributes in farmers' decisions to allocate area among varieties ...
Single nucleotide polymorphism genotyping using Kompetitive Allele Specific PCR (KASP): overview of the technology and its application in crop improvement
Single nucleotide polymorphism (SNP) data can be obtained using one of the numerous uniplex or multiplex SNP genotyping platforms that combine a variety of chemistries, detection methods, and reaction formats. Kompetitive ...
