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

open access: yesG3: 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 ...

Fine mapping of multiple QTL using combined linkage and linkage disequilibrium mapping – A comparison of single QTL and multi QTL methods [PDF]

open access: yesGenetics Selection Evolution, 2007
Two previously described QTL mapping methods, which combine linkage analysis (LA) and linkage disequilibrium analysis (LD), were compared for their ability to detect and map multiple QTL.

postQTL: a QTL mapping R workflow to improve the accuracy of true positive loci identification

open access: yesBMC Research Notes, 2022
Objective The determination of the location of quantitative trait loci (QTL) (i.e., QTL mapping) is essential for identifying new genes. Various statistical methods are being incorporated into different QTL mapping functions.

Joint QTL linkage mapping for multiple-cross mating design sharing one common parent. [PDF]

open access: yesPLoS ONE, 2011
BackgroundNested association mapping (NAM) is a novel genetic mating design that combines the advantages of linkage analysis and association mapping. This design provides opportunities to study the inheritance of complex traits, but also requires more ...

Inclusive Composite Interval Mapping of QTL by Environment Interactions in Biparental Populations. [PDF]

open access: yesPLoS ONE, 2015
Identification of environment-specific QTL and stable QTL having consistent genetic effects across a wide range of environments is of great importance in plant breeding. Inclusive Composite Interval Mapping (ICIM) has been proposed for additive, dominant

Multi-parental fungal mapping population study to detect genomic regions associated with Pyrenophora teres f. teres virulence

open access: yesScientific Reports, 2023
In recent years multi-parental mapping populations (MPPs) have been widely adopted in many crops to detect quantitative trait loci (QTLs) as this method can compensate for the limitations of QTL analyses using bi-parental mapping populations.

Multi-QTL mapping for quantitative traits using epistatic distorted markers. [PDF]

open access: yesPLoS ONE, 2013
The interaction between segregation distortion loci (SDL) has been often observed in all kinds of mapping populations. However, little has been known about the effect of epistatic SDL on quantitative trait locus (QTL) mapping.

Estimating genetic variance contributed by a quantitative trait locus: A random model approach.

open access: yesPLoS Computational Biology, 2022
Detecting quantitative trait loci (QTL) and estimating QTL variances (represented by the squared QTL effects) are two main goals of QTL mapping and genome-wide association studies (GWAS).

Multiple QTL for horticultural traits and quantitative resistance to Phytophthora infestans linked on Solanum habrochaites chromosome 11. [PDF]

open access: yes, 2014
Previously, a Phytophthora infestans resistance QTL from Solanum habrochaites chromosome 11 was introgressed into cultivated tomato (S. lycopersicum). Fine mapping of this resistance QTL using near-isogenic lines (NILs) revealed some co-located QTL with ...

Mean-Variance QTL Mapping Identifies Novel QTL for Circadian Activity and Exploratory Behavior in Mice

open access: yesG3: Genes, Genomes, Genetics, 2018
We illustrate, through two case studies, that “mean-variance QTL mapping”—QTL mapping that models effects on the mean and the variance simultaneously—can discover QTL that traditional interval mapping cannot.
