a

E-QTLi and E-QTLj are the two QTLs involved in epistatic interaction.

b

Linkage group and the estimated confidence interval of QTL position in brackets (in Kosambi cM).

c

F values of significance of each epistatic interaction.

d

Estimated additive-by-additive epistatic effect. Positive values indicate that alleles from PHA1037 increase the trait value, and negative values indicate that the increase in the trait is due to the presence of the alleles from PMB0225.

e

Percentage of the phenotypic variation explained by additive-by-additive epistatic effects.

Experiment-wide P-value.

*P = 0.05,

**

P = 0.01,

***

P = 0.001.

SDC, stem disease score; SAUDPC, stem area under the disease progress curve; PDC, petiole disease score; PAUDPC, petiole area under the disease progress curve; LDC, leaf disease score; LAUDPC, leaf area under the disease progress curve.
