Combining two Meishan F2 crosses improves the detection of QTL on pig chromosomes 2, 4 and 6 [PDF]

, 2010
Background In pig, a number of experiments have been set up to identify QTL and a multitude of chromosomal regions harbouring genes influencing traits of interest have been identified. However, the mapping resolution remains limited in most cases and the

Multiple-trait quantitative trait locus mapping with incomplete phenotypic data

BMC Genetics, 2008
Background Conventional multiple-trait quantitative trait locus (QTL) mapping methods must discard cases (individuals) with incomplete phenotypic data, thereby sacrificing other phenotypic and genotypic information contained in the discarded cases. Under

QTL linkage analysis of connected populations using ancestral marker and pedigree information [PDF]

, 2012
The common assumption in quantitative trait locus (QTL) linkage mapping studies that parents of multiple connected populations are unrelated is unrealistic for many plant breeding programs.

Quantitative Trait Loci Affecting Milk Production Traits in Finnish Ayrshire Dairy Cattle [PDF]

, 2003
A whole genome scan of Finnish Ayrshire was conducted tomap quantitative trait loci (QTL) affecting milk production. The analysis included 12 half-sib families containing a total of 494 bulls in a granddaughter design.

Detection of QTLs controlling heading date in the process of rice development at two environments

浙江大学学报. 农业与生命科学版, 2002
Heading date (HD) is a major determinant of the regional and seasonal adaptation of rice varieties. In order to elucidate the quantitative trait loci (QTL) for HD in the process of rice development, a doubled haploid (DH) population was employed to map ...

Gene and QTL detection in a three-way barley cross under selection by a mixed model with kinship information using SNPs [PDF]

, 2011
Quantitative trait locus (QTL) detection is commonly performed by analysis of designed segregating populations derived from two inbred parental lines, where absence of selection, mutation and genetic drift is assumed.

Efficient detection of QTL with large effects in a simulated pig-type pedigree using selective genotyping [PDF]

, 2009
Background The ultimate goal of QTL studies is to find causative mutations, which requires additional expression studies. Given the limited amount of time and funds, the smart option is to identify the most important QTL with minimal effort.
