how do you get seedless watermelons?

Answer 1

"Seedless" watermelon is actually a bit misleading because they do contain a few small, pale seeds. Here is how:

"They are the product of crossing a female tetraploid plant (itself the product of genetic manipulation, using colchicine) with diploid pollen. The resulting triploid plant is sterile, but will produce the seedless fruit if pollenized by a diploid plant. For this reason, commercially available seedless watermelon seeds actually contain two varieties of seeds; that of the triploid seedless plant itself (recognizable because the seed is larger), and the diploid plant which is needed to pollenize the triploid. Unless both plant types are grown in the same vicinity, no seedless fruit will result. This system for growing seedless watermelons was first developed by H. Kihara in Japan and subsequently improved by O J Eigsti in partnership with Kihara. This scientific relationship was begun at the Third International Genetics Congress, held in Stockholm, Sweden in 1948."

One thing I learned the other day by watching a gardening show on tv is that you must plant a regular seeded watermelon plant near to your seedless variety in order for them to cross-pollinate, as the seedless cannot pollinate itself.

Happy Gardening!

Answer 2

they use selective breeding , using a plants traits to breed that trait into the fruit its called hybridization, or selective breeding

Answer 3

They sell them here, and I have no idea without seed.......
how's it done?
