what makes watermelon seedless
Hereâs what they have to say: âA seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.espite being the new kid on the block, the seedless watermelon actually outsells its seeded peers by a significant margin. According to the National Watermelon Promotion Board, only 16 percent of watermelon sold in grocery stores has seeds. In 2003, that number was 43 percent.
