*Seed coat color traits include L*, a*, b*, L, a, b, X, Y and Z. Seed size traits include 7 indicators of length (sl), width (sw), length-to-width ratio(l/w), perimeter (sp), diameter (sd), area (sa) and circularity (sc)
The gene action model (GAM) includes additive (A), partial dominance (PD), dominance (D), over-dominance (OD)
‘R²’ indicates the contribution rate of the locus to the phenotype
Check marks in the last two columns indicate that the QTL was detected at a specific trial site; HN, Hainan field trial location; YY, Yuanyang field trial location
