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 ...

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 ...
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 ...
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 ...
Proceedings of a Workshop held at CIMMYT
This publication describes in collaborative efforts to conserve, document, and characterize seed collections of maize from the Americas over the last decade, as reported in a workshop at the International Maize and Wheat ...
Comparative SNP and haplotype analysis reveals a higher genetic diversity and rapider LD decay in tropical than temperate germplasm in maize
Understanding of genetic diversity and linkage disequilibrium (LD) decay in diverse maize germplasm is fundamentally important for maize improvement. A total of 287 tropical and 160 temperate inbred lines were genotyped ...
Latin American maize germplasm regeneration and conservation
During 1992-96, a collaborative project involving genebanks of 14 countries in Latin America, with economic and/or technical support from USDA under project Noah, the USDA-ARS National Seed Storage Laboratory (NSSL), and ...
