Are yellow watermelons genetically modified?
No, yellow watermelons are not genetically modified. In fact, yellow watermelons are naturally-occurring, that is, they evolved to their present color naturally, through human cultivation paired with unintentional and/or intentional selective breeding. According to reports, the ancestor of the modern watermelon was a fruit very much resembling present watermelons, but with a hard, pale, whitish green, rather unpalatable flesh. Since it stored water, it was deemed a precious commodity and picked up for cultivation. Over time, human cultivation of the fruit naturally resulted in the modern watermelon varieties with sweet, juicy and crisp pink, red, salmon, white, orange and yellow flesh.
What is yellow watermelon crossed with?
There are well over 1000 different cultivated varieties of watermelon. The most popular varieties belong to the Citrullus lanatus species and are sweet, crisp and extremely juicy. But to get to their present form, color and taste, they were once cross-bred from what would now be dubbed as inferior watermelons until traits such as yellow flesh color (or pink, red or orange), sweetness, juiciness and crispness were obtained to the desired level.
Why are yellow watermelons yellow?
Yellow watermelons are yellow because they are low in a pigment called lycopene and high in pigments called xanthophylls. Lycopene is a pigment and carotenoid antioxidant that gives pink and red-fleshed watermelons their characteristic color (and tomatoes, guava, grapefruit and red carrots). Yellow watermelon has very low levels of lycopene. Instead, it’s higher in yellow xanthophylls, notably neoxanthin, but also violaxanthin, neochrome and lutein, hence its yellow flesh color.
By comparison, what makes watermelon red inside is a high content of red lycopene pigments which dominate the color palette. Similarly, what makes orange watermelon orange inside is a high content of orange beta-carotene which dominates the pigment profile resulting in the specific flesh color.
