fullsibQTL: an R package for QTL mapping in biparental populations of outcrossing species

Abstract

ABSTRACTAccurate QTL mapping in outcrossing species requires software programs which consider genetic features of these populations, such as markers with different segregation patterns and different level of information. Although the available mapping procedures to date allow inferring QTL position and effects, they are mostly not based on multilocus genetic maps. Having a QTL analysis based in such maps is crucial since they allow informative markers to propagate their information to less informative intervals of the map. We developedfullsibQTL, a novel and freely availableRpackage to perform composite interval QTL mapping considering outcrossing populations and markers with different segregation patterns. It allows to estimate QTL position, effects, segregation patterns, and linkage phase with flanking markers. Additionally, several statistical and graphical tools are implemented, for straightforward analysis and interpretations.fullsibQTLis anRopen source package withCandRsource code (GPLv3). It is multiplatform and can be installed fromhttps://github.com/augusto-garcia/fullsibQTL.
