a
A LOD score of 5.0 was used for declaring the existence of putative pairs of epistatic QTL, according to the method of Lynch and Walsh (1998).
b
Variance (%) for locus is the proportion of variance explained by the component epistasis.
c
Variance (%) for trait is the total variance of this trait explained by all epistatic QTL detected in a population.
d
Phenotypic effect is the effect arising from interactions between alleles at the loci i and j, as defined by Mather and Jinks (1982).
