The efficiency of mapping of quantitative trait loci using cofactor analysis in half-sib design [PDF]

Genetics Selection Evolution, 2006
This simulation study was designed to study the power and type I error rate in QTL mapping using cofactor analysis in half-sib designs. A number of scenarios were simulated with different power to identify QTL by varying family size, heritability, QTL ...

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

Mapping carcass and meat quality QTL on Sus Scrofa chromosome 2 in commercial finishing pigs [PDF]

, 2009
Quantitative trait loci (QTL) affecting carcass and meat quality located on SSC2 were identified using variance component methods. A large number of traits involved in meat and carcass quality was detected in a commercial crossbred population: 1855 pigs ...

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.

Comparison of analyses of the QTLMAS XIV common dataset. II: QTL analysis [PDF]

, 2011
Background - A quantitative and a binary trait for the 14th QTLMAS 2010 workshop were simulated under a model which combined additive inheritance, epistasis and imprinting. This paper aimed to compare results submitted by the participants of the workshop.

Identification of QTL and candidate genes involved in early seedling growth in rice via high-density genetic mapping and RNA-seq

Crop Journal, 2021
Early seedling vigor (ESV) is a major breeding target in rice, especially under direct seeding. To identify quantitative trait locus (QTL) affecting ESV, a recombinant inbred line population derived from a cross between 02428 and YZX, two cultivars ...

A Bayesian approach to detect QTL affecting a simulated binary and quatitative trait [PDF]

, 2011
Background - We analyzed simulated data from the 14th QTL-MAS workshop using a Bayesian approach implemented in the program iBay. The data contained individuals genotypes for 10,031 SNPs and phenotyped for a quantitative and a binary trait. Results - For

Multi-environment QTL mixed models for drought stress adaptation in wheat [PDF]

, 2008
Many quantitative trait loci (QTL) detection methods ignore QTL-by-environment interaction (QEI) and are limited in accommodation of error and environment-specific variance.

Mapping QTLs for cold tolerance at seedling stage using an Oryza sativa × O. rufipogon backcross inbred line population

Czech Journal of Genetics and Plant Breeding, 2018
Tolerance to low temperature is an important factor affecting the growth and development of rice (Oryza sativa L.) at an early growing season in the temperate region, and at high altitudes of tropical regions. In this study, a backcross inbred line (BIL)

Verification of QTL for grain starch content and its genetic correlation with oil content using two connected RIL populations in high-oil maize. [PDF]

PLoS ONE, 2013
Grain oil content is negatively correlated with starch content in maize in general. In this study, 282 and 263 recombinant inbred lines (RIL) developed from two crosses between one high-oil maize inbred and two normal dent maize inbreds were evaluated ...
