Growing Seedless Watermelons. If youâve enjoyed a delicious seedless watermelon, you might wonder how they are grown. It starts by treating watermelon seedlings with a chemical that makes the plant have 4 times (4X) their normal number of chromosomes. After planting, when this watermelon flowers, it receives pollen from a nearby normal (2X) watermelon. The result is a fruit that has seeds that are 3X .
Iâve noticed some discussion online lately about seedless watermelons and claims that they are âgenetically modified,â which somehow makes them a black sheep in the world of produce.espite being the new kid on the block, the seedless watermelon actually outsells its seeded peers by a significant margin. According to the National Watermelon Promotion Board, only 16 percent of watermelon sold in grocery stores has seeds. In 2003, that number was 43 percent.
