The genetic dissection of quantitative traits in crops
(Pontificia Universidad Católica de Valparaíso, 2010)
Most traits of interest in plant breeding show quantitative inheritance, which complicate the breeding process since phenotypic performances only partially reflects the genetic values of individuals. The genetic variation ...

High-density mapping of triple rust resistance in barley using DArT-Seq markers
(Frontiers, 2019)
The recent availability of an assembled and annotated genome reference sequence for the diploid crop barley (Hordeum vulgare L.) provides new opportunities to study the genetic basis of agronomically important traits such ...

Genome-wide association for grain morphology in synthetic hexaploid wheats using digital imaging analysis
(licensee BioMed Central Ltd, 2014)
Grain size and shape greatly influence grain weight which ultimately enhances grain yield in wheat. Digital imaging (DI) based phenomic characterization can capture the three dimensional variation in grain size and shape ...

Association analysis of resistance to cereal cyst nematodes (Heterodera avenae) and root lesion nematodes (Pratylenchus neglectus and P. thornei) in CIMMYT advanced spring wheat lines for semi-arid conditions
(Japanese Society of Breeding, 2016)
To identify loci linked to nematode resistance genes, a total of 126 of CIMMYT advanced spring wheat lines adapted to semi-arid conditions were screened for resistance to Heterodera avenae, Pratylenchus neglectus, and P. ...

Genome-wide association study based on multiple imputation with low-depth sequencing data: application to biofuel traits in reed canarygrass
(Genetics Society of America, 2015)
Genotyping by sequencing allows for large-scale genetic analyses in plant species with no reference genome, but sets the challenge of sound inference in presence of uncertain genotypes. We report an imputation-based ...

Bin mapping of tomato diversity array (DArT) markers to genomic regions of Solanum lycopersicum x Solanum pennellii introgression lines
(Springer, 2012)
Marker-trait association studies in tomato have progressed rapidly due to the availability of several populations developed between wild species and domesticated tomato. However, in the absence of whole genome sequences ...

Fine mapping of leaf rust resistance gene Lrzh84 using expressed sequence tag and sequence-tagged site markers, and allelism with other genes on wheat chromosome 1b
(American Phytopathological Society (APS), 2013)
Zhou 8425B, possessing the leaf rust resistance gene LrZH84, is an elite wheat (Triticum aestivum) parental line in the Yellow-Huai Valley region of China. In the present study, 2,086 F2 plants derived from Zhou 8425B/Chinese ...

Quantitative trait loci mapping in maize for resistance to larger grain borer
(Consiglio per la Ricerca e la Sperimentazione in Agricoltura, 2018)
Storability of maize grain is constrained by the larger grain borer (LGB) (Prostephanus truncatus). Host plant resistance is the most feasible way to manage LGB among smallholder farmers. Breeding for resistance to this ...
