Table 3 Two-way ANOVA results displaying significant effects of ploidy level and hybridity on important agronomic traits. Both F1 2× hybrids (EA) and (EB) and F1 3× hybrids (EAA) and (EBB) and their parent lines (EE), (AA), (BB), (AAAA) and (BBBB) were grouped according to ploidy level (diploid, triploid, tetraploid; factor 1) or hybridity (isogenic, hybrid; factor 2)
