R/qtl: high-throughput multiple QTL mapping [PDF]

Bioinformatics, 2010
AbstractMotivation: R/qtl is free and powerful software for mapping and exploring quantitative trait loci (QTL). R/qtl provides a fully comprehensive range of methods for a wide range of experimental cross types. We recently added multiple QTL mapping (MQM) to R/qtl.

Quantitative trait loci for bone traits segregating independently of those for growth in an F-2 broiler X layer cross [PDF]

, 2007
An F broiler-layer cross was phenotyped for 18 skeletal traits at 6, 7 and 9 weeks of age and genotyped with 120 microsatellite markers. Interval mapping identified 61 suggestive and significant QTL on 16 of the 25 linkage groups for 16 traits.

Copulas in QTL Mapping [PDF]

Behavior Genetics, 2004
The standard variance components method for mapping quantitative trait loci is derived on the assumption of normality. Unsurprisingly, statistical tests based on this method do not perform so well if this assumption is not satisfied. We use the statistical concept of copulas to relax the assumption of normality and derive a test that can perform well ...

Identification and Validation of Quantitative Trait Loci for Grain Number in Rice (Oryza sativa L.)

Agronomy, 2020
Grains number is one of the most important agronomic traits in the determination of rice productivity. To explore the underlying genetic basis of grain number in rice, quantitative trait locus (QTL) analysis was performed using three recombinant inbred ...

Study of association between morphological traits and QTLs governing sheath blight resistance in rice (Oryza sativa L.)

Electronic Journal of Plant Breeding, 2022
Rice sheath blight is one of the most serious diseases of rice. In the current study, the relationship between morphological traits and sheath blight resistance was investigated by using 1545 recombinant inbred lines.

Bayesian multi-QTL mapping for growth curve parameters [PDF]

, 2010
Background Identification of QTL affecting a phenotype which is measured multiple times on the same experimental unit is not a trivial task because the repeated measures are not independent and in most cases show a trend in time. A complicating factor is

R/qtl: QTL mapping in experimental crosses

Bioinformatics, 2003
Abstract Summary: R/qtl is an extensible, interactive environment for mapping quantitative trait loci (QTLs) in experimental populations derived from inbred lines. It is implemented as an add-on package for the freely-available statistical software, R, and includes functions for estimating genetic maps, identifying genotyping errors, and

Quantitative Trait Loci (QTL) for Forage Traits in Intermediate Wheatgrass When Grown as Spaced-Plants versus Monoculture and Polyculture Swards

Agronomy, 2019
It has been hypothesized that the genetic control of forage traits, especially biomass, for grass plants growing as spaced-plants versus swards is different.

Identification of new TRAP markers linked to chlorophyll content, leaf senescence, and cell membrane stability in water-stressed wheat

Biologia Plantarum, 2014
In order to identify target region amplification polymorphism (TRAP) markers linked to three physiological traits in wheat (Triticum aestivum L.), the segregating F4 population from the cross between drought-sensitive (Yecora Rojo) and drought-tolerant ...
