Interactions of fsqs8.1 in different genetic situations. a Comparison of CALC8-1, SC8-3 and CALC8-1-x-SC8-3 hybrid fruit shape indexes. The blue bar indicates the expected mid-parent mean, and the asterisk the significance of the contrast (p = 0.0002). b Interaction between a and fsqs8.1 in an F₂ population from the cross between CALC8-1 and ‘Mucha Nesvi’ (MN, a monoecious traditional cultivar). The means for the four homozygous allele combinations for the two loci (CALC/MN) for fsqs8.1, ANDRO/MONO for andromonoecious/monoecious (a), are shown on the left and the significance of the gene effects and interactions according two-way ANOVA on the right. c The fruit shape index of fruits from hybrids between accessions belonging to different melon horticultural groups with PS and CALC8-1 is depicted on the left. On the right, the significance of the effects (GB, genetic background, fsqs8.1 PS or CALC8-1 allele at the locus, and the two years) and their interactions from the three-way ANOVA, are shown
