A matrix of QTL effects contributing to CyHV-3 survival in 14 families. Rows are for families (mapping families or BC1 families belonging to either Y or D backgrounds). First four columns are for main QTL effects, followed by columns for QTL–QTL interaction effects, and by a column for family % survival in a descending order. Numbers in cells are the significance level of the association test as an approximation for effect size. P-values above 0.1 are not shown. NP non-polymorphic families
