Significant markers that are repeated between the traits days to flowering and days to maturity are in bold, while those that are repeated within days to flowering between years and treatments are in bold italic
aQTL name based on association with days to flowering (Df), or days to maturity (Dm). Decimal number represents linkage group and QTL order
bEnvironments including drought and irrigated treatments as described in text
cEmpirical LOD thresholds based on 1000 permutations used for QTL detection as recommended by Churchill and Doerge (1994) are indicated in the final column
dDetermination coefficients based on marker (R 2) and model including background markers (TR 2)
