Will seedless watermelon crosspollinate and contaminate the seeded watermelon used to pollinate them?
I'm considering using a heirloom variety as the pollinator, but want to keep the heirloom seeds pure. I think seedless watermelons need a pollinator cause their flowers are mainly female, so I'm not too sure if it will cross due to the lack of males.
I thought I made it clear that I understand how heirloom seeds work, and am explicitly trying to save the seeds, not keeping the quality of the first generation fruit. What I am unclear of is how seedless watermelons differ from seeded watermelons in their plant growth, and why they need a seeded watermelon. I thought it was because seedless watermelons produce small or no amounts of male flowers and so need a pollinator.
