Real answer: seeds are plated, seedlings germinate, plants grow, flowers are born, get pollinated, THEN farmer sprays acetylene on early fruits and this gas inhibits seed development. So when you want to get more seedless fruits, you acetylene them.

Seed Production. The obvious question asked about growing seedless watermelons is: "How does one obtain seed of a seedless watermelon?" Obviously, you cannot save seed from a seedless watermelon. So, where do the seeds come from? Simply stated, the number of chromosomes (the threadlike bodies within cells that contain the inheritance units called genes) in a normal watermelon plant is doubled by the use of the chemical colchicine. Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a "mule" of the plant kingdom, and it produces seedless watermelons. Seed of seedless varieties are available from most major seed companies.

The "seedless" watermelon I've seen still has little seeds in it. They're white and soft and you can eat them, so they're not as "seedy" as regular watermelon. But for stuff that really is seedless, like seedless grapes, I guess you get cuttings (for grapes) and graft them or root them to make new plants. Watermelons grow from seeds, though, so you just get the hybrid cross or ethylene, I guess, like the earlier answers said (I didn't know about the ethylene.)
But I hate watermelon, so I wouldn't grow any kind of them.

Well, it the watermelon you buy in the stores would have to be some sort of hybrid cross that results in a lack of seeds. I'm not sure any more details than that, but basically, you would have to create the hybrid each time you wanted a crop of watermelons.

You always grow watermelon from seed. To make them more palatable by making them "seedless" you prevent their pollination by insects or wind. If the flowers are not pollinated the seeds wont develop.

They have seeds, but they aren't hard, so you can eat them. I don't know if they would grow though.
