Table 4.

Locations in cM from the centromere for QTL on each pair of chromosomes (CH1 and CH2) exhibiting significant (P < 0.001) epistasis for SPEED. Shown are the F statistics that test overall epistasis with their associated probabilities (* = P < 0.05 at the suggestive Bonferroni threshold level). For each pairwise QTL combination, the individual standardized epistatic components that reached statistical significance also are given.
