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 ...
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 ...
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 ...
Three new teosintes (Zea spp., Poaceae) from Mexico
Premise of the study : Teosinte species are the closest relatives of maize and represent an important but increasingly rare genetic resource for maize improvement and the study of evolution by domestication. Three ...
Gene flow among different teosinte taxa and into the domesticated maize gene pool
Maize (Zea mays L. ssp. mays) was domesticated from one wild species ancestor, the Balsas teosinte (Zea mays ssp. parviglumis) about 9000 years ago. Higher levels of gene diversity are found in teosinte taxa compared to ...
Evaluation of Zapalote Chico accessions for conservation and enhancement
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Valorizzazione qualitativa dei cereali, 2006)
Conserving traditional maize (Zea mays L.) landraces grown by farmers in Latin America can con- tribute to food security. Core subsets of such landraces that represents that diversity can be used for their en- hancement. ...
Cluster analysis, an approach to sampling variability in maize accessions
Cluster analysis is frequently used to classify maize (Zen mays L.) accessions and can be used by breeders and geneticists to identify subsets of accessions which have potential utility for specific breeding or genetic ...
Molecular characterization of global maize breeding germplasm based on genome-wide single nucleotide polymorphisms
Characterization of genetic diversity is of great value to assist breeders in parental line selection and breeding system design. We screened 770 maize inbred lines with 1,034 single nucleotide polymorphism (SNP) markers ...
