Genetic characterization and linkage disequilibrium estimation of a global maize collection using SNP markers
(Public Library of Science, 2009)
A newly developed maize Illumina GoldenGate Assay with 1536 SNPs from 582 loci was used to genotype a highly diverse global maize collection of 632 inbred lines from temperate, tropical, and subtropical public breeding ...
Genetic distance based on SSR markers and testcross performance of maize inbred lines
(National Institute of Genetic Engineering and Biotechnology, 2006)
The identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. In some cases, pedigree information has been used to select diverse parental lines. In ...
An 11-bp insertion in Zea mays fatb reduces the palmitic acid content of fatty acids in Maize grain
(Public Library of Science, 2011)
The ratio of saturated to unsaturated fatty acids in maize kernels strongly impacts human and livestock health, but is a complex trait that is difficult to select based on phenotype. Map-based cloning of quantitative trait ...
Empirical comparison of simple sequence repeats and single nucleotide polymorphisms in assessment of maize diversity and relatedness
(Public Library of Science, 2007)
While Simple Sequence Repeats (SSRs) are extremely useful genetic markers, recent advances in technology have produced a shift toward use of single nucleotide polymorphisms (SNPs). The different mutational properties of ...
Genetic association mapping identifies single nucleotide polymorphisms in genes that affect abscisic acid levels in maize floral tissues during drought
(Oxford University Press; Society for Experimental Biology, 2011)
In maize, water stress at flowering causes loss of kernel set and productivity. While changes in the levels of sugars and abscisic acid (ABA) are thought to play a role in this stress response, the mechanistic basis and ...
Sampling strategies for conserving maize diversity when forming core subsets using genetic markers
(Crop Science Society of America (CSSA), 2006)
Core subsets can be formed on the basis of molecular markers and different sampling strategies. This research used genetic markers on three maize data sets for studying 24 stratified sampling strategies to investigate which ...
Comparison of the performance of synthetic maize varieties created based on either genetic distance or general combining ability of the parents
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2012)
Synthetics varieties are grown by farmers and used by breeders to select new inbred lines. In countries unable to market hybrids, use of synthetics leads to yield improvements over landraces. Synthetics are derived from ...
Advances in maize genomics and their value for enhancing genetic gains from breeding
(Hindawi Publishing Corporation, 2009)
Maize is an important crop for food, feed, forage, and fuel across tropical and temperate areas of the world. Diversity studies at genetic, molecular, and functional levels have revealed that, tropical maize germplasm, ...
Characterization of mandarin (Citrus spp.) using morphological and AFLP markers
Sixty-three mandarin (Citrus spp.) cultivars from the collection of the Campo Citrícola Experimental Francisco Villa, Tamaulipas, Mexico, were evaluated using morphological and Amplified Fragment Length Polymorphism (AFLP) ...
Development of a fingerprinting database and assembling an SSR reference kit for genetic diversity analysis of wheat
(Institute of Crop Sciences, 2006)
Understanding of the current and expanded genetic diversity is very important for raising the yield of wheat. Genetic diversity based on molecular markers has been studied in plants for over thirty decades. SSR is the ...
