Abbreviations: LG, linkage group; QTL, quantitative trait locus.
Effect size values reflect the difference in means of the two genotypes at the QTL (see Materials and methods for trait units). For traits where the parents were distinct, a positive effect size means that the QTL moved the trait toward I. tenuifolia; a negative effect size means that the QTL moved the trait away from I. tenuifolia (antagonistic QTL). For traits where the parents were not distinct, the sign of effect size simply reflects the QTL's influence on the trait value, and expected direction is necessarily left blank. For the two composite traits, it was not possible to estimate QTL size parameters.
Placed after the LGs that harbored the loci involved in the one significant epistatic effect detected.
