Desarrollo, mantenimiento y multiplicación de semilla de variedades de polinización libre
Los procedimientos para la producción de semilla de híbridos de maíz y el mantenimiento de líneas progenitoras están bien documentados. Sin embargo, poco se ha escrito acerca del desarrollo, mantenimiento y multiplicación ...
Detection of genetic integrity of conserved maize (Zea mays L.) germplasm in genebanks using SNP markers
Twenty maize landrace accessions regenerated and conserved in five maize genebanks were investigated for genetic integrity using 1,150 Single Nucleotide Polymorphisms (SNPs) and 235 SNP haplotypes. The genetic diversity ...
CIMMYT 1986, hechos y tendencias mundiales relacionados con el maíz : aspectos economicos de la produccion de semilla de variedades comerciales de maiz en los paises en desarrollo
A viable maize seed industry is a key element in the extension of improved maize varieties to Third World farmers. In this report, the worldwide use and price of maize seed is analyzed by seed type. A discussion of issues ...
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 ...
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 ...
The genetic architecture of flowering time and photoperiod sensitivity in maize as revealed by QTL review and meta analysis
The control of flowering is not only important for reproduction, but also plays a key role in the processes of domestication and adaptation. To reveal the genetic architecture for flowering time and photoperiod sensitivity, ...
Seed testing of maize and wheat : a laboratory guide
Breeding for drought and nitrogen stress tolerance in maize : from theory to practice
Targeted initially for maize breeders in sub-Saharan Africa, the content is based on a successful approach developed at CIMMYT for improving the tolerance of maize to drought and low nitrogen stress. Intended as a supplement ...
