List of consistent QTLs* detected on chromosome 3A using data recorded over fourteen different environment years.

**For years 2005 and 2008 data was recorded at Lincoln and Pullman, respectively; SPSM = spike/square meter, PH = plant height, HD = heading date, TKW = 1000-kernel weight, GY = grain yield, KPSM = kernels/square meter, GVWT = grain volume weight, and KPS = kernels per spike.*For the purpose of identifying consistent QTLs, the QTLs detected in overlapping marker intervals with one common marker flanking the region were treated as the same QTL. Among these QTLs the marker interval showing the highest LOD score and R2 value was documented in the table (cf. table S4 for complete list of QTLs).
