R/qtl: high-throughput multiple QTL mapping [PDF]

open access: yesBioinformatics, 2010
AbstractMotivation: R/qtl is free and powerful software for mapping and exploring quantitative trait loci (QTL). R/qtl provides a fully comprehensive range of methods for a wide range of experimental cross types. We recently added multiple QTL mapping (MQM) to R/qtl.

Copulas in QTL Mapping [PDF]

open access: yesBehavior Genetics, 2004
The standard variance components method for mapping quantitative trait loci is derived on the assumption of normality. Unsurprisingly, statistical tests based on this method do not perform so well if this assumption is not satisfied. We use the statistical concept of copulas to relax the assumption of normality and derive a test that can perform well ...

QTL Mapping to QTL Cloning: Mice to the Rescue [PDF]

open access: yesGenome Research, 1997
With the availability of dense, highly informative marker maps, it has recently become feasible to map genes (Quantitative Trait Loci or QTL) accounting for part of the heritability of continuously distributed traits in experimental crosses as well as outbred populations. QTL mapping efforts have almost invariably revealed a limited number of loci with

R/qtl: QTL mapping in experimental crosses

open access: yesBioinformatics, 2003
Abstract Summary: R/qtl is an extensible, interactive environment for mapping quantitative trait loci (QTLs) in experimental populations derived from inbred lines. It is implemented as an add-on package for the freely-available statistical software, R, and includes functions for estimating genetic maps, identifying genotyping errors, and

Identifying signatures of recent selection in Holstein cattle in the tropic

open access: yesRevista Colombiana de Ciencias Pecuarias, 2018
Background: Holstein cattle have undergone strong selection processes in the world. These selection signatures can be recognized and utilized to identify regions of the genome that are important for milk yield.

A chromosome-wide QTL mapping on chromosome 2 to identify loci affecting live weight and carcass traits in F2 population of Japanese quail

open access: yesCzech Journal of Animal Science, 2016
The Japanese quail (Coturnix japonica) is a considerable species which is often used for animal modelling in breeding researches. This study aims to detect quantitative trait loci (QTL) underlying growth and carcass traits in Japanese quail.

Linkages and Interactions Analysis of Major Effect Drought Grain Yield QTLs in Rice. [PDF]

open access: yesPLoS ONE, 2016
Quantitative trait loci conferring high grain yield under drought in rice are important genomic resources for climate resilient breeding. Major and consistent drought grain yield QTLs usually co-locate with flowering and/or plant height QTLs, which could

Molecular markers: their use in tree improvement

open access: yesJournal of Forest Science, 2012
Earlier breeders used phenotypic selection based on morphological characteristics to improve tree varieties. These selections often take many cycles of breeding and backcrossing in order to place desired characteristics. But today the knowledge has paved

Special issue in honour of Prof. Reto J. Strasser - Additive main effect and digenic epistatic quantitative trait loci for chlorophyll fluorescence traits influencing salt tolerance at seedling stage in rice

open access: yesPhotosynthetica, 2020
In this investigation, an attempt was made to identify quantitative trait locus (QTL)/gene associated with JIP-test parameters in rice. Thirty main effect additive QTLs (M-QTLs) along with more than 500 digenic epistatic QTLs were detected using a ...

Univariate and Multivariate QTL Analyses Reveal Covariance Among Mineral Elements in the Rice Ionome

open access: yesFrontiers in Genetics, 2021
Rice provides more than one fifth of daily calories for half of the world’s human population, and is a major dietary source of both essential mineral nutrients and toxic elements. Rice grains are generally poor in some essential nutrients but may contain
