Although it sounds silly, the seedless watermelon is grown from seed! For an explanation of this somewhat complex process, see the web link to the left. In fact triploid seeds of watermelon used for raising the crop produce seedless watermelon because ovules are aborted due to irregular meiosis during gametogenesis . The triploid seeds are produced by crossing tetraploid female flowers with diploid pollen grains. In triploid plants there are three sets of chromosomes and hence pairing of homologous chromosomes is not possible which obstruct the process of normal gamete formation.
The first seedless grapes were the Thompson green seedless grapes. All seedless come from this stock. They were discovered and not invented by Thompson.
