Genetic background- and environment-independent QTL and candidate gene identification of appearance quality in three MAGIC populations of rice

Frontiers in Plant Science, 2022
Many QTL have been identified for grain appearance quality by linkage analysis (LA) in bi-parental mapping populations and by genome-wide association study (GWAS) in natural populations in rice.

Nested Association Mapping of Stem Rust Resistance in Wheat Using Genotyping by Sequencing.

PLoS ONE, 2016
We combined the recently developed genotyping by sequencing (GBS) method with joint mapping (also known as nested association mapping) to dissect and understand the genetic architecture controlling stem rust resistance in wheat (Triticum aestivum).

A New Advanced Backcross Tomato Population Enables High Resolution Leaf QTL Mapping and Gene Identification

G3: Genes, Genomes, Genetics, 2016
Quantitative Trait Loci (QTL) mapping is a powerful technique for dissecting the genetic basis of traits and species differences. Established tomato mapping populations between domesticated tomato (Solanum lycopersicum) and its more distant interfertile ...

Bayesian QTL mapping using skewed Student-t distributions

Genetics Selection Evolution, 2002
In most QTL mapping studies, phenotypes are assumed to follow normal distributions. Deviations from this assumption may lead to detection of false positive QTL.

Exome QTL-seq maps monogenic locus and QTLs in barley [PDF]

BMC Genomics, 2017
QTL-seq, in combination with bulked segregant analysis and next-generation sequencing (NGS), is used to identify loci in small plant genomes, but is technically challenging to perform in species with large genomes, such as barley. A combination of exome sequencing and QTL-seq (exome QTL-seq) was used to map the mono-factorial Mendelian locus black ...

The effect of an imprecise map on interval mapping QTLs

Genetical Research, 2004
The statistical analysis of quantitative trait locus (QTL) experiments relies on the use of a linkage map of the markers genotyped. Such a map is, at best, a good estimate of the true map. Resources might be diverted into developing better marker maps or improved maps become available after the analysis, raising concerns over the original analysis.

The Beavis Effect in Next-Generation Mapping Panels in Drosophila melanogaster

G3: Genes, Genomes, Genetics, 2017
A major goal in the analysis of complex traits is to partition the observed genetic variation in a trait into components due to individual loci and perhaps variants within those loci.

Novel QTL and Meta-QTL Mapping for Major Quality Traits in Soybean

Frontiers in Plant Science, 2021
Isoflavone, protein, and oil are the most important quality traits in soybean. Since these phenotypes are typically quantitative traits, quantitative trait locus (QTL) mapping has been an efficient way to clarify their complex and unclear genetic ...

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

Advanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.

Statistical Methods for Mapping Multiple QTL [PDF]

International Journal of Plant Genomics, 2008
Since Lander and Botstein proposed the interval mapping method for QTL mapping data analysis in 1989, tremendous progress has been made in the last many years to advance new and powerful statistical methods for QTL analysis. Recent research progress has been focused on statistical methods and issues for mapping multiple QTL together.
