seedless fruits

Quoted By:

how do we have different strains of seedless bananas, or for that matter different strains of seedless fruit in general? Did each of these varieties come from it's own individual seeded ancestor, or is there some way to change the genes of seedless fruit?

Bananas were wiped out by a virus for being too genetically similar thanks to us cultivating them. Every banana tree now is cloned from another tree.

I know that most bananas are clones, the question is how do you get new cultivars of bananas. Since there are hundreds of cultivars there must be a way to make them, and since banana we eat don't have seeds, how do you make a new cultivar?

Dessert bananas are triploid hybrids between Musa acuminata and Musa balbisiana.
Different strains may be produced either by mutagenesis of the seeds produced by the pre-hybrid generation or by hybridising different strains of M. acuminata and M. balbisiana.

thanks man, this was the answer I was looking for. So basically all seedless cultivars are triploids from a combination of two parents. So kind of like the mules of the plant world.

actually, mutagenesis can also be performed in a pretty clever way by doing vegetative propagation, see https://en.wikipedia.org/wiki/List_of_banana_cultivars#Cultivars

kind of, yeah.
Its the same mechanism behind seedless grapes.
