Only significant effects (P < 0.01) are shown. A negative value signifies an increasing effect of the Col-0 allele. The dominance ratio d*/|a*| for all significant QTL was calculated using effects estimated in Z ₁ (a*) and Z ₂ (d*). QTL were classified as additive (A; |d*/a*| < 0.2), partially dominant (PD; 0.2 ≤ |d*/a*| < 0.8), dominant (D; 0.8 ≤ |d*/a*| < 1.2), and overdominant (OD; |d*/a*| ≥ 1.2)
