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

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]
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
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
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.

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

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
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
