Construction of a potato consensus map and QTL meta-analysis offer new insights into the genetic architecture of late blight resistance and plant maturity traits

BMC Plant Biology, 2011
Background Integrating QTL results from independent experiments performed on related species helps to survey the genetic diversity of loci/alleles underlying complex traits, and to highlight potential targets for breeding or QTL cloning.

Analysis of Homozygous-by-Descent (HBD) Segments for Purebred and Crossbred Pigs in Russia

Life, 2021
Intensive selection raises the efficiency of pig farming considerably, but it also promotes the accumulation of homozygosity, which can lead to an increase in inbreeding and the accumulation of deleterious variation.

QTL Mapping and Heterosis Analysis for Fiber Quality Traits Across Multiple Genetic Populations and Environments in Upland Cotton

Frontiers in Plant Science, 2018
An “immortalized F2” (IF2) population and two reciprocal backcross (HSBCF1 and MARBCF1) populations were constructed to investigate the genetic bases of fiber quality traits in upland cotton across four different environments.

Mapping of Main-Effect and Epistatic Quantitative Trait Loci for Internal Egg Traits in an F2 Resource Population of Chickens

The Journal of Poultry Science, 2014
Quantitative trait loci (QTLs) analyses for internal egg quality of chickens were performed with 143 microsatellite markers on 27 linkage groups in 371 F2 hens obtained from an intercross between Japanese Large Game (Oh-Shamo) and White Leghorn breeds ...

Modelos aleatórios na estimação da localização de QTLs em famílias de meios-irmãos Random model approach for estimation of QTL location in half-sibs families

Revista Brasileira de Zootecnia, 2005
O procedimento de mapeamento por intervalo baseado em modelo aleatório foi aplicado para estudar sua robustez e propriedades no mapeamento de dois QTLs, em populações constituídas de famílias de meios-irmãos.

QTL analysis of high thermotolerance with superior and downgraded parental yeast strains reveals new minor QTLs and converges on novel causative alleles involved in RNA processing. [PDF]

PLoS Genetics, 2013
Revealing QTLs with a minor effect in complex traits remains difficult. Initial strategies had limited success because of interference by major QTLs and epistasis. New strategies focused on eliminating major QTLs in subsequent mapping experiments.

QTL identification for nine seed-related traits in Brassica juncea using a multiparent advanced generation intercross (MAGIC) population

Czech Journal of Genetics and Plant Breeding, 2021
Agronomic traits are usually determined by multiple quantitative trait loci (QTLs) that can have pleiotropic effects. A multiparent advanced generation intercross (MAGIC) population is well suited for genetically analysing the effects of multiple QTLs on

QTL Analysis for Grain Iron and Zinc Concentrations in Two O. nivara Derived Backcross Populations

Rice Science, 2018
Identification of quantitative trait loci (QTLs) for grain mineral elements can assist in faster and more precise development of micronutrient dense rice varieties through marker-assisted breeding.

Lint percentage and boll weight QTLs in three excellent upland cotton (Gossypium hirsutum): ZR014121, CCRI60, and EZ60

BMC Plant Biology, 2023
Background Upland cotton (Gossypium hirsutum L.) is the most economically important species in the cotton genus (Gossypium spp.). Enhancing the cotton yield is a major goal in cotton breeding programs.

eQTL Catalogue 2023: New datasets, X chromosome QTLs, and improved detection and visualisation of transcript-level QTLs.

PLoS Genetics, 2023
The eQTL Catalogue is an open database of uniformly processed human molecular quantitative trait loci (QTLs). We are continuously updating the resource to further increase its utility for interpreting genetic associations with complex traits.
