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 ...
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 ...
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 ...
Genetic characterization of a core set of a tropical maize race Tuxpeño for further use in maize improvement
The tropical maize race Tuxpeño is a well-known race of Mexican dent germplasm which has greatly contributed to the development of tropical and subtropical maize gene pools. In order to investigate how it could be exploited ...
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 ...
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 ...
Genetic diversity in CIMMYT nontemperate maize germplasm: Landraces, open pollinated varieties, and inbred lines
CIMMYT is the source of improved maize (Zea mays L.) breeding material for a significant portion of the nontemperate maize growing world. Landraces which did not serve as sources for improved maize germplasm may contain ...
