QTL IciMapping Version 3.3 released

    QTL IciMapping is freely-available public software, capable of building high-density linkage genetic maps and mapping quantitative trait loci (QTL). Version 3.3 of the software was released in July 2013. Eight fully implemented functionalities in QTL IciMapping v3.3 are: (1) BIN: Binning of redundant markers; (2) MAP: Construction of genetic linkage maps in biparental populations; (3) BIP: Mapping of additive and digenic epistasis genes in biparental populations; (4) CSL: Mapping of additive and digenic epistasis genes with chromosome segment substitution lines; (5) MET: QTL by environment interaction in biparental populations; (6) NAM: QTL mapping in nested association mapping populations; (7) SDL: Mapping of segregation distortion loci in biparental populations; and (8) CMP: Consensus map construction from multiple genetic linkage maps sharing common markers. Two supplementary tools in QTL IciMapping v3.3 are: (1) 2pointREC: Estimation of recombination frequency between two loci in 20 biparental populations; and (2) ANOVA: Analysis of variance of multi-environmental trials.
