Table 6.

Interaction for effects of combinations of presence (+) and absence (−) of nuclear markers with presence (+) or absence (−) of D-type cytoplasm on resistance to late blight and plant maturity in the GBC population. In case differences were found among marker classes, two-way ANOVA was performed to explore the factors contributing the differences
