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 ...
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 ...
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 ...
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 ...

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 ...
