QTL detection and allelic effects for growth and fat traits in outbred pig populations [PDF]

, 2004
Quantitative trait loci (QTL) for growth and fatness traits have previously been identified on chromosomes 4 and 7 in several experimental pig populations.

BioMercator 4 : A complete framework to integrate QTL, meta-QTL, and genome annotation.

, 2014
International audienceCompilation of genetic maps combined to QTL meta-analysis has proven to be a powerful approach contributing to the identification of candidate genes underlying quantitative traits. One of the most interesting properties of meta-QTL (

Maize Combined Insect Resistance Genomic Regions and Their Co-localization With Cell Wall Constituents Revealed by Tissue-Specific QTL Meta-Analyses

Frontiers in Plant Science, 2018
Combinatorial insect attacks on maize leaves, stems, and kernels cause significant yield losses and mycotoxin contaminations. Several small effect quantitative trait loci (QTL) control maize resistance to stem borers and storage pests and are correlated ...

Major Co-localized QTL for Plant Height, Branch Initiation Height, Stem Diameter, and Flowering Time in an Alien Introgression Derived Brassica napus DH Population

Frontiers in Plant Science, 2018
Plant height (PH), branch initiation height (BIH), and stem diameter (SD) are three stem-related traits that play crucial roles in plant architecture and lodging resistance.

Detection of QTL with effects on osmoregulation capacities in the rainbow trout (Oncorhynchus mykiss) [PDF]

, 2011
Background There is increasing evidence that the ability to adapt to seawater in teleost fish is modulated by genetic factors. Most studies have involved the comparison of species or strains and little is known about the genetic architecture of the ...

Bayes factors for detection of Quantitative Trait Loci

Genetics Selection Evolution, 2001
A fundamental issue in quantitative trait locus (QTL) mapping is to determine the plausibility of the presence of a QTL at a given genome location. Bayesian analysis offers an attractive way of testing alternative models (here, QTL vs.

Sensitivity of methods for estimating breeding values using genetic markers to the number of QTL and distribution of QTL variance [PDF]

, 2010
The objective of this simulation study was to compare the effect of the number of QTL and distribution of QTL variance on the accuracy of breeding values estimated with genomewide markers (MEBV).

Construction and integration of genetic linkage maps from three multi-parent advanced generation inter-cross populations in rice

Rice, 2020
Background The construction of genetic maps based on molecular markers is a crucial step in rice genetic and genomic studies. Pure lines derived from multiple parents provide more abundant genetic variation than those from bi-parent populations. Two four-
