If you grow seedless watermelons, you know that seeds for these watermelons are more difficult to produce and don't germinate as well as those seeds you may have enjoyed spitting. With the seedless watermelon, you get a fruit you can put in your refrigerator and eat a month later, if you wish. The seedless watermelon lasts much longer than a watermelon with seeds, because seeds contribute to the breakdown of the flesh. There are other positive attributes to the seedless watermelon. It is more resistant to many diseases than watermelons with seeds.
Seedless varieties have a tough rind that endures the bumps during shipping.
Some varieties can be designed more precisely for their growing environment and for the consumer. If you're a Clemson Tiger, you may want an orange- striped fruit that can be eaten at a single sitting. In the future, you might just see such a fruit displayed at fruit stands in South Carolina where the Tigers prowl.
