Answer 1

I actually worked on a farm for two summers that grew the seeds for seedless watermelon. It was all done by careful cross breeding. So you would have several strains of watermelon plant that when cross pollinated will produce a plant whose seeds grow infertile plants. This farmer had been working on these plants for about 15 years and he has continued in the 15 years since. He also grew yellow and orange watermelon and even had produced a tie-dye red and orange.
