Causal graphical models in systems genetics: A unified framework for joint inference of causal network and genetic architecture for correlated phenotypes [PDF]
Annals of Applied Statistics 2010, Vol. 4, No. 1, 320-339, 2010 Causal inference approaches in systems genetics exploit quantitative trait loci (QTL) genotypes to infer causal relationships among phenotypes. The genetic architecture of each phenotype may be complex, and poorly estimated genetic architectures may compromise the inference of causal relationships among phenotypes.

Fourteen years of R/qtl: Just barely sustainable [PDF]
Broman, K.W. 2014. Fourteen Years of R/qtl: Just Barely
Sustainable. Journal of Open Research Software 2(1):e11, 2013 R/qtl is an R package for mapping quantitative trait loci (genetic loci that contribute to variation in quantitative traits) in experimental crosses. Its development began in 2000. There have been 38 software releases since 2001. The latest release contains 35k lines of R code and 24k lines of C code, plus 15k lines of code for the documentation ...

Quantitative Genetics and Functional-Structural Plant Growth Models: Simulation of Quantitative Trait Loci Detection for Model Parameters and Application to Potential Yield Optimization [PDF]
Annals of Botany 101, 8 (2008) 1243-1254, 2010 Background and Aims: Prediction of phenotypic traits from new genotypes under untested environmental conditions is crucial to build simulations of breeding strategies to improve target traits. Although the plant response to environmental stresses is characterized by both architectural and functional plasticity, recent attempts to integrate biological ...

BMC Genomics, 2020 Background Restoration of fertility (Rf) is an important trait for pigeonpea hybrid breeding. Few coarse quantitative trait locus (QTL) studies conducted in the past identified QTLs with large confidence intervals on the genetic map and could not provide

The Journal of Poultry Science, 2017 Chickens display a wide spectrum of phenotypic variations in quantitative traits such as egg-related traits. Quantitative trait locus (QTL) analysis is a statistical method used to understand the relationship between phenotypic (trait measurements) and ...

An efficient hierarchical generalized linear mixed model for mapping QTL of ordinal traits in crop cultivars. [PDF]
PLoS ONE, 2013 Many important phenotypic traits in plants are ordinal. However, relatively little is known about the methodologies for ordinal trait association studies.

Novel Resampling Improves Statistical Power for Multiple-Trait QTL Mapping
G3: Genes, Genomes, Genetics, 2017 Multiple-trait analysis typically employs models that associate a quantitative trait locus (QTL) with all of the traits. As a result, statistical power for QTL detection may not be optimal if the QTL contributes to the phenotypic variation in only a ...

Multiple-line inference of selection on quantitative traits [PDF]
Genetics 201 (1), 305-322 (2015), 2014 Trait differences between species may be attributable to natural selection. However, quantifying the strength of evidence for selection acting on a particular trait is a difficult task. Here we develop a population-genetic test for selection acting on a quantitative trait which is based on multiple-line crosses.

Frontiers in Plant Science, 2020 Wheat is one of the most important food crops in the world, but as a cool-season crop, it is more prone to heat stress, which severely affects crop production and grain quality.
