How do seedless watermelons continue to exist season after season?

Answer by  blahblah (670)

Every year, seed producers make the cross between two types of watermelons to produce new seedless watermelon seed. Tetraploid watermelon plants are crossed with diploid or normal watermelon plants to produce watermelons with triploid seed. The triploid seed produces seedless watermelon.

Seedless watermelons are hybrid varieties, created from two or more different varieties, that will set fruit without pollination. No pollination = no seeds. The seed producers will re-hybridize the same varieties every year to keep a supply of seedless watermelons year after year.

You cross a watermelon plant with two sets of chromosomes with a watermelon plant with four sets of chromosomes.....with the pollenation abilities of bees. The result is a seed with 3 sets of chromosomes which produces a fruit that generally doesn't produce seeds.

Genetic Modification. There are also various ways of planting plants without the need for seeds, which include and are not limited to grafting, budding and rooting.

Just like mules (cross between horse and donkey) can continue to exist even though each one is sterile. Essentially the seedless watermelon comes from genetically altered watermelon seeds that produce fruits that are sterile.
