* QTL that don’t overlap with maturity QTL or phenology genes;
# the QTL peak is between the indicated markers;
Chr. = chromosome; LOD = logarithm of the odds; QTL x E = QTL x environment interaction; PVE = percent of variance explained by the QTL; “-”: no significant QTL detected in that environment; the superscript letters represent the source of the high value allele (C = Commander, F = Fleet, W = WI4304).
