^aBarley chromosome on which the QTL was determined.
^bGenetic position of the peak marker and range of the QTL in cM, based on Comadran et al. [35].
^cMarker of the QTL with the highest significance (peak marker).
^dNumber of families, in which peak marker is segregating.
^eSignificance of the peak marker, expressed as P_BON-HOLM.
^fCross-validated proportion of explained genotypic variance of peak marker.
^gFrequency of significant detections of the peak marker in 100 five-fold cross-validation runs.
^hDifference between the wild genotype and the cultivated genotype in days until flowering. Early flowering effects of exotic alleles are indicated in red.
ⁱCandidate gene, potentially explaining the QTL effect with reference.
