Identification of stable QTL controlling multiple yield components in a durum × cultivated emmer wheat population under field and greenhouse conditions

G3: Genes, Genomes, Genetics, 2022
Crop yield gains are needed to keep pace with a growing global population and decreasing resources to produce food. Cultivated emmer wheat is a progenitor of durum wheat and a useful source of genetic variation for trait improvement in durum.

Detection of QTL for traits related to adaptation to sub-optimal climatic conditions in chickens

Genetics Selection Evolution, 2017
Background Growth traits can be used as indicators of adaptation to sub-optimal conditions. The current study aimed at identifying quantitative trait loci (QTL) that control performance under variable temperature conditions in chickens.

Mapping of Two Major QTLs Controlling Flowering Time in Brassica napus Using a High-Density Genetic Map

Plants, 2022
Research on the flowering habit of rapeseed is important for the selection of varieties adapted to specific ecological environments. Here, quantitative trait loci (QTL) for the days-to-flowering trait were identified using a doubled haploid population of

The best of both worlds: Combining population genetic and quantitative genetic models [PDF]

, 2021
Numerous traits under migration-selection balance are shown to exhibit complex patterns of genetic architecture with large variance in effect sizes. However, the conditions under which such genetic architectures are stable have yet to be investigated, because studying the influence of a large number of small allelic effects on the maintenance of ...

The X Chromosome in Quantitative Trait Locus Mapping [PDF]

Genetics, 2006
AbstractThe X chromosome requires special treatment in the mapping of quantitative trait loci (QTL). However, most QTL mapping methods, and most computer programs for QTL mapping, have focused exclusively on autosomal loci. We describe a method for appropriate treatment of the X chromosome for QTL mapping in experimental crosses.

Deciphering mechanisms underlying the genetic variation of general production and liver quality traits in the overfed mule duck by pQTL analyses

Genetics Selection Evolution, 2017
Background The aim of this study was to analyse the mechanisms that underlie phenotypic quantitative trait loci (QTL) in overfed mule ducks by identifying co-localized proteomic QTL (pQTL).

Likelihood Ratio Test process for Quantitative Trait Locus detection [PDF]

, 2014
International audienceWe consider the likelihood ratio test (LRT) process related to the test of the absence of QTL (a QTL denotes a quantitative trait locus, i.e.

Quantitative trait locus analysis for hemostasis and thrombosis [PDF]

Mammalian Genome, 2008
Susceptibility to thrombosis varies in human populations as well as many in inbred mouse strains. The objective of this study was to characterize the genetic control of thrombotic risk on three chromosomes. Previously, utilizing a tail-bleeding/rebleeding assay as a surrogate of hemostasis and thrombosis function, three mouse chromosome substitution ...

Mapping genetic determinants of host susceptibility to Pseudomonas aeruginosa lung infection in mice. [PDF]

, 2016
Background: P. aeruginosa is one of the top three causes of opportunistic human bacterial infections. The remarkable variability in the clinical outcomes of this infection is thought to be associated with genetic predisposition.

Quantitative Trait Locus Analysis for Rice Yield Traits under Two Nitrogen Levels

Rice Science, 2015
A recombinant inbred line population derived from a super hybrid rice Xieyou 9308 (Xieqingzao B/Zhonghui 9308) and its genetic linkage map were used to detect quantitative trait loci (QTLs) for rice yield traits under the low and normal nitrogen (N ...
