ADD, additive genetic model as defined in Table 2; ADD + EPI, additive and epistasis genetic model as defined in Table 2; H, heritability in the broad sense; PIN, the largest P-value for entering variables; POUT, the smallest P-value for removing variables.

^aAll significant positives not located in the 10 predefined QTL intervals.
