Dimensions of diversity in CIMMYT bread wheat from 1965 to 2000
To the extent possible, this paper summarizes scientific evidence on the scope of the genetic base in modern bread wheat varieties in the developing world from 1965 to the present, drawing on previously published research ...
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 ...
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 ...
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) ...
Relationship, evolutionary fate and function of two maize co-orthologs of rice GW2 associated with kernel size and weight
(BioMed Central, 2010)
Background: In rice, the GW2 gene, found on chromosome 2, controls grain width and weight. Two homologs of this gene, ZmGW2-CHR4 and ZmGW2-CHR5, have been found in maize. In this study, we investigated the relationship, ...
Core Hunter: an algorithm for sampling genetic resources based on multiple genetic measures
(BioMed Central, 2009)
Background: Existing algorithms and methods for forming diverse core subsets currently address either allele representativeness (breeder's preference) or allele richness (taxonomist's preference). The main objective of ...
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 ...
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 ...
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 ...
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, ...
