Over several years, large efforts have been made to produce crop genetic and genomic data at genome scale. To take full advantage of these data, integration is required at various levels of resolution. QTL mapping can generally be undertaken on different populations and levels of inbreeding (e.g., F3; RILs). Integrative QTL meta-analysis methods have been developed to take full advantage of existing results to more accurately predict the most probable location of QTL. Methods have also been devised to build consensus map by integrating genetic map and QTL map positions and making it easier to search for co-localization between genes and QTL. These methods have been implemented into the BioMercator V2.1 software thanks to the previous support of Génoplante and The Generation Challenge program.


Compared to the previous versions, BioMercator V3 will include several new map compilation and meta-analysis algorithms from the MetaQTL package. The graphical user interface has also been improved and offers new display options (compact information representation) and zooming tools. BioMercator V3 will be fully connected to the URGI GnpMap databases.


The software will be released freely in 2011
