Watermelon is a summertime staple, and more prevalently we’re seeing it available in our grocery stores all throughout the year. Delightfully and deliciously, we can have our watermelon as much as we like and as often as we like. Seedless watermelon has made our lives easier, adding to the convenience of taking watermelon on the go as a snack or a refreshing post-workout fuel but also adding to the versatility we now have to play with watermelon in a huge variety of recipes.

 

Regardless, the burning question is, “Where do seedless watermelons come from if they have no seeds?” And, of course, the related query, “How do you grow seedless watermelons with no seeds?” Where do Seedless Watermelons Come From? First off, seedless watermelons are not completely seed-free. There are some small, almost transparent, seeds to be found in the melon; they are unremarkable and edible. Occasionally, you will find a “true” seed in a seedless variety.

 

Seedless watermelons were invented over 50 years ago, and they have few or no seeds. When we say seeds, we are talking about mature seeds, the black ones. Oftentimes, the white seed coats where a seed did not fully mature are assumed to be seeds. But this isn’t the case! They are perfectly safe to swallow while eating, and don’t worry – no watermelons will grow in your stomach despite the old wives’ tale.

So, how are seedless watermelons grown? Chromosomes are the building blocks that give characteristics, or traits, to living things including plants and watermelons. Watermelon breeders discovered that crossing a diploid plant (bearing the standard two sets of chromosomes) with a tetraploid plant (having four sets of chromosomes) results in a fruit that produces a triploid seed. (Yes, it has three sets of chromosomes.) This triploid seed is the seed that produces seedless watermelons!

 

In other words, a seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell. When this seeded fruit matures, the small, white seed coats inside contain 33 chromosomes, rendering it sterile and incapable of producing seeds. This is similar to the mule, produced by crossing a horse with a donkey – simple cross-breeding. And to be clear on the subject, this is not genetic modification. Cross-breeding is two parents and their offspring.

 

Importantly and interestingly, seedless watermelon still need to be pollinated by their seeded parent, so oftentimes growers will plant seeded and seedless in their field. However, the seeded commercial harvest and retail sales only add up to about 8%, meaning seedless watermelon makes up for 92% of all watermelon sales.
