a
Chri and Chrj represent the chromosomes that loci i and loci j are located on, respectively.
b
Ai and Aj are the main effects of loci i and loci j, and AAij is the epistatic effect between loci i and j.
c
Percentage of the total variation explained by AAij.
d
The epistasis dominance degree (EDD) of digenic interaction. Digenic interactions were classified according to their |dd/aa| ratio as additive (A) (|dd/aa| < 0.2), partial dominance (PD) (0.2 ≤ |dd/aa| < 0.8), dominance (D) (0.8 ≤ |dd/aa| < 1.2), and overdominance (OD) (|dd/aa| ≥ 1.2).
