I was eating some Crimson Sweet Watermelon out of our garden this morning and it got me to wondering how do you get seed to plant a "seedless" Watermelon. I had to go look it up and thought some others might be interested in one of those things that was never thought about before. 
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.
