Are white watermelons genetically modified?

White watermelons are not genetically modified organisms (GMO). They actually occur naturally, as a result of selective plant breeding efforts. White watermelon fruit are thought to precede the modern pink and red fleshed varieties. In fact, a few thousand years ago all watermelons had a greenish-white, hard and rather unpalatable flesh, more like modern day white citron melons, aka white citron watermelons. As a result of cultivation efforts, watermelon slowly became sweeter, less dense and crisper, as well as developed new flesh colors (pink, red, yellow, orange).

Why are white watermelons white inside?

What does it mean when a watermelon is white inside? Simply put, white watermelons have little pigment to their flesh. What makes red watermelon red inside is a type of red carotenoid pigment called lycopene. Yellow watermelon is yellow inside because of yellow carotenoid pigments called xanthophylls (e.g. lutein, zeaxanthin, neoxanthin, violaxanthin, neochrome). Orange watermelons owe their flesh color primarily to orange carotenoid pigments such as beta-carotene.

By comparison, white watermelon is low in red, orange and yellow pigments that give other varieties their colors.
