FIGURE 1.

(A) The funnel breeding design, used across the six generations (G1–G6), to develop the 420 S3 individuals of the S3MEGGIC population. The eight parents, coded from A to H and each with a different colour to represent their genomic background, are represented above at a scale based on the real fruit size. Scale bar represents 5 cm. The four two-way hybrids obtained in the G1 generation (AB, CD, EF, and GH) are also represented at the same scale as the founders. Phenotyping of founders and two-way hybrids for absence (red) or presence (green) of anthocyanins in vegetative plant tissues (PA) and fruit epidermis (FA), or anthocyanic pigmentation under the calyx (PUC). White dots for PUC mean uncertainty for non-anthocyanin fruits. (B) A representation of the phenotypic diversity of the S3 individuals found during the phenotyping. (C) Distribution of molecular markers across the chromosomes used for the genotyping.
