Meta-analysis of constitutive and adaptive QTL for drought tolerance in maize
The response of plants to drought stress is very complex and involves expression of a lot of genes and pathways for diverse mechanisms and interactions with environments. Many quantitative trait loci(QTL) mapping experiments ...
Recombination frequency variation in maize as revealed by genomewide single-nucleotide polymorphisms
Recombination frequency greatly affects selection efficiency in plant breeding. A high-density single-nucleotide polymorphism (SNP) map integrated with physical map and other molecular maps is very useful for characterizing ...
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 ...
CIMMYT's maize germplasm management, improvement, and utilization program
Improving the maize plant is the subject of this publication. It first outlines several population improvement schemes and then focuses on the approach that CIMMYT has adopted in its own maize program. The structure and ...
Statistical properties of QTL linkage mapping in biparental genetic populations
Quantitative trait gene or locus (QTL) mapping is routinely used in genetic analysis of complex traits. Especially in practical breeding programs, questions remain such as how large a population and what level of marker ...
Factors affecting the accuracy of genotype imputation in populations from several maize breeding programs
Genomic selection and association mapping offer great potential to increase rates of genetic progress in plants. The prediction of genomic breeding values usually requires that missing genotypes be imputed because a ...
Toward a cost-effective fingerprinting methodology to distinguish maize open-pollinated varieties
In Africa, many smallholder farmers grow openpollinated maize (Zea mays L.) varieties (OPVs), which allow seed recycling and outyield traditional unimproved landraces. Seeds of productive OPVs are provided to farmers, often ...
Breeding and selection for drought resistance in tropical maize
Throughout the lowland wet tropics, periodic nonprotracted drought caused by irregular rainfall distribution is responsible for sizable reductions in maize yield. This is particularly true when reduced water availability ...
Natural genetic variation in lycopene epsilon cyclase tapped for maize biofortification
Dietary vitamin A deficiency causes eye disease in 40 million children each year and places 140 to 250 million at risk for health disorders. Many children in sub-Saharan Africa subsist on maize-based diets. Maize displays ...
