Fine mapping of multiple QTL using combined linkage and linkage disequilibrium mapping – A comparison of single QTL and multi QTL methods [PDF]
Two previously described QTL mapping methods, which combine linkage analysis (LA) and linkage disequilibrium analysis (LD), were compared for their ability to detect and map multiple QTL.

A New Advanced Backcross Tomato Population Enables High Resolution Leaf QTL Mapping and Gene Identification [PDF]
Quantitative Trait Loci (QTL) mapping is a powerful technique for dissecting the genetic basis of traits and species differences. Established tomato mapping populations between domesticated tomato (Solanum lycopersicum) and its more distant interfertile ...

Fast genetic mapping of complex traits in C. elegans using millions of individuals in bulk [PDF]
QTL mapping in multicellular animals usually requires generation, maintenance, and phenotyping large panels of recombinant individuals. Here, the authors develop ceX-QTL mapping, a method for fast genetic mapping via bulk selection on millions of unique ...

Mapping multiple QTL using linkage disequilibrium and linkage analysis information and multitrait data [PDF]
A multi-locus QTL mapping method is presented, which combines linkage and linkage disequilibrium (LD) information and uses multitrait data. The method assumed a putative QTL at the midpoint of each marker bracket.

postQTL: a QTL mapping R workflow to improve the accuracy of true positive loci identification
Objective The determination of the location of quantitative trait loci (QTL) (i.e., QTL mapping) is essential for identifying new genes. Various statistical methods are being incorporated into different QTL mapping functions.

Joint QTL linkage mapping for multiple-cross mating design sharing one common parent. [PDF]
BackgroundNested association mapping (NAM) is a novel genetic mating design that combines the advantages of linkage analysis and association mapping. This design provides opportunities to study the inheritance of complex traits, but also requires more ...

Inclusive Composite Interval Mapping of QTL by Environment Interactions in Biparental Populations. [PDF]
Identification of environment-specific QTL and stable QTL having consistent genetic effects across a wide range of environments is of great importance in plant breeding. Inclusive Composite Interval Mapping (ICIM) has been proposed for additive, dominant

In recent years multi-parental mapping populations (MPPs) have been widely adopted in many crops to detect quantitative trait loci (QTLs) as this method can compensate for the limitations of QTL analyses using bi-parental mapping populations.

Multi-QTL mapping for quantitative traits using epistatic distorted markers. [PDF]
The interaction between segregation distortion loci (SDL) has been often observed in all kinds of mapping populations. However, little has been known about the effect of epistatic SDL on quantitative trait locus (QTL) mapping.

A framework for gene mapping in wheat demonstrated using the Yr7 yellow rust resistance gene [PDF]
We used three approaches to map the yellow rust resistance gene Yr7 and identify associated SNPs in wheat. First, we used a traditional QTL mapping approach using a double haploid (DH) population and mapped Yr7 to a low-recombination region of chromosome
