Figure 5.

Fruit flesh color and carotenoid levels of various melon genotypes. Transected fruit at 20 DAA (left) and mature stage (right) are shown. A, Transected fruits of low-β and yofi parental lines (top) and the four possible allelic combinations (bottom). CmOr genotypes (CmOr-His and Cmor-lowβ) are indicated on the left, and CRTISO genotypes (the wild type and nonsense mutated crtiso) are indicated on the top of each image. B, Transected fruits of yofi and NY parental lines (top) and the four possible allelic combinations (bottom). C and D, Average amounts (μg g⁻¹ fresh weight [FW]) of phytoene, lutein, prolycopene, and β-carotene accumulated at 20 DAA (C) and in mature fruit (D) of F2 defined segregants derived from yofi × low-β (CmOr-His and Cmor-lowβ) and from yofi × NY (Cmor-Arg) crosses. WT, Wild type. Exact numbers and se values are given in Supplemental Table S2.
