A QTL study was performed in large half-sib families to characterize the genetic background of variation in pork quality traits as well as to examine the possibilities of including QTL in a marker-assisted selection scheme. The quality traits included ultimate pH in LM and the semimembranosus, drip loss, and the Minolta color measurements L*, a*, and b* representing meat lightness, redness, and yellowness, respectively. The families consist of 3,883 progenies of 12 Duroc boars that were… 
Genome-wide mapping and functional analysis of genes determining the meat quality in pigs
TLDR
In chapter one QTL were mapped and tested for pairwise epistasis for meat quality traits in three connected porcine F2 crosses comprising around 1000 individuals, and putative candidate genes in the vicinity of significant SNPs found in the association analysis were searched.
Joint QTL mapping and gene expression analysis identify positional candidate genes influencing pork quality traits
TLDR
The performance of an eQTL search for SNPs mapping to the regions associated with meat quality traits demonstrated that the GM a* SSC3 and pH24 SSC17 QTL display positional concords with cis-eQTL regulating the expression of several genes with a potential role on muscle metabolism.
A two-step approach to map quantitative trait loci for meat quality in connected porcine F(2) crosses considering main and epistatic effects.
TLDR
To map QTL for meat quality traits in three connected porcine F(2) crosses comprising around 1000 individuals, nine orthogonal forms of epistasis were found and the most interesting chromosome was SSC6.
Genome-wide Association Study to Identify Quantitative Trait Loci for Meat and Carcass Quality Traits in Berkshire
TLDR
The significant QTL after characterization of the functional candidate genes on the QTL or around theQTL region may be effectively and efficiently used in marker assisted selection to achieve enhanced genetic improvement of the trait considered.
Genome-Wide Association Study of Meat Quality Traits in a White Duroc×Erhualian F2 Intercross and Chinese Sutai Pigs
TLDR
A genome-wide association study using the Illumina PorcineSNP60K Beadchip found thirteen new candidate genes for IMF, marbling and firmness, on the basis of their positions, functional annotations and reported expression patterns, which will contribute to further identification of the causal mutation underlying these QTLs and future marker-assisted selection in pigs.
Quantitative trait loci analysis of a Duroc commercial population highlights differences in the genetic determination of meat quality traits at two different muscles.
TLDR
Interestingly, there was low positional concordance between meat quality QTL maps obtained for GM and LTL, which suggests that QTL effects might be modulated to a certain extent by genetic and environmental factors linked to muscle function and anatomical location.
Genome-wide association analyses for meat quality traits in Chinese Erhualian pigs and a Western Duroc × (Landrace × Yorkshire) commercial population
TLDR
Seven novel QTL for meat characteristics are revealed, which suggests the existence of common underlying variants that may differ in frequency across populations and provides valuable insights into the molecular basis of convergent evolution of meat quality traits in Chinese and Western breeds that show divergent phenotypes.
A Whole Genome Association Study on Meat Quality Traits Using High Density SNP Chips in a Cross between Korean Native Pig and Landrace
TLDR
A whole genome association study was performed to detect significant polymorphisms for meat quality traits in an F2 cross population that were generated with Korean native pig sires and Landrace dams in Songwhan, Korea, and about 32 to 66% of the total phenotypic variation was explained by the significant SNPs for each trait.

The current study was carried out to perform QTL mapping on swine chromosome 6 (SSC6) associated to meat quality traits. The F2 population was produced by outbreed crossing using two native Brazilian
Detection and characterization of quantitative trait loci for meat quality traits in pigs.
TLDR
Failure of the line-cross approach to detect the meat color QTL suggests that the founder lines have similar allele frequencies for these QTL, and the benefit of analyzing experimental data under different genetic and statistical models is shown.
Characterization of quantitative trait loci for growth and meat quality in a cross between commercial breeds of swine.
TLDR
The objectives of this advanced phase of the project were to further identify and characterize QTL after genotyping for another 33 markers in special regions of interest, and to develop and apply methods for detecting QTL with parent-of-origin effects.

TLDR
Use of these results for marker-assisted selection offers opportunities for improving pork quality by within-line selection after showing that QTL affecting carcass composition and meat quality traits segregated within commercial lines.
A further look at quantitative trait loci affecting growth and fatness in a cross between Meishan and Large White pig populations
TLDR
A detailed quantitative trait locus (QTL) analysis of growth and fatness data from a three generation experimental cross between Large White and Meishan pig breeds was carried out, revealing the presence of two linked QTLs segregating on chromosome 1, affecting growth traits during the post-weaning period.
