Mapping QTL for grain yield and plant traits in a tropical maize population
The genetic dissection of quantitative traits in crops
(Pontificia Universidad Católica de Valparaíso, 2010)
QTL and eQTL mapping associated with host response to Candidatus Liberibacter asiaticus in citrandarins
Huanglongbing (HLB) is a severe disease of citrus caused by the bacterium Candidatus Liberibacter. In America, the most common species is Candidatus Liberibacter asiaticus (CLas). In a previous study of the Citrus-HLB ...
A mixed model QTL analysis for sugarcane multiple-harvest-location trial data
(SPRINGERNEW YORK, 2012)
Sugarcane-breeding programs take at least 12 years to develop new commercial cultivars. Molecular markers offer a possibility to study the genetic architecture of quantitative traits in sugarcane, and they may be used in ...
Composite interval mapping and mixed models reveal QTL associated with performance and carcass traits on chicken chromosomes 1, 3, and 4
Interval mapping (IM) implemented in QTL Express or GridQTL is widely used, but presents some limitations, such as restriction to a fixed model, risk of mapping two QTL when there may be only one and no discrimination of ...
Quantitative trait loci associated with fatness in a broiler-layer cross
(Wiley-Blackwell Publishing, Inc, 2009-10-01)
P>An F(2) population established by crossing a broiler male line and a layer line was used to map quantitative trait loci (QTL) affecting abdominal fat weight, abdominal fat percentage and serum cholesterol and triglyceride ...
Generalized composite interval mapping offers improved efficiency in the analysis of loci influencing non-normal continuous traits
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2010)
QTL mapping for yield components in a tropical maize population using microsatellite markers
(BLACKWELL PUBLISHING, 2008)
QTL mapping provides usefull information for breeding programs since it allows the estimation of genomic locations and genetic effects of chromossomal regions related to the expression of quantitative traits. The objective ...
Assessing the value of phenotypic information from non-genotyped animals for QTL mapping of complex traits in real and simulated populations
Background: QTL mapping through genome-wide association studies (GWAS) is challenging, especially in the case of low heritability complex traits and when few animals possess genotypic and phenotypic information. When most ...
Quantitative trait loci associated with chemical composition of the chicken carcass
Major objectives of the poultry industry are to increase meat production and to reduce carcass fatness, mainly abdominal fat. Information on growth performance and carcass composition are important for the selection of ...
