gMean plant height (in cm) of WM lines carrying homozygous Julius alleles (J) at both loci
hMean plant height (in cm) of WM lines carrying homozygous Non-Julius alleles (N) at both loci
iMean plant height (in cm) of WM lines carrying a homozygous Julius allele (J) and a Non-Julius allele (N) at loci 1 and 2, respectively
jMean plant height (in cm) of WM lines carrying a homozygous Non-Julius allele (N) and a Julius allele (J) at loci 1 and 2, respectively
kEstimated additive by additive epistatic interaction effect (aa) [45]
Bold letters indicate markers located in regions containing main QTL for plant height (Table 3)
NA = data not available, in this case, the epistatic interaction effect was estimated by adding twice the mean plant height of the JN group
