Where do the seeds come from to grow seedless grapes ?

mementoflash

Grape breeders create new seedless plants by placing the pollen of a seedless grape onto the flowers of a grape variety that has seeds. They then cut open and inspect the fruit of every single plant that grows from this match. The breeders are looking for seeds -- some plants will have seeds in their fruit and others won't. When they find a plant that has no seeds, or maybe just has very tiny traces of seeds that you wouldn't be able to taste, the grape breeders use it to make more seedless plants. One way is to cut off small pieces of the seedless plant's vine and place it in special growing conditions in a greenhouse. Eventually, the pieces of vine will grow roots and become new, individual plants. This technique is called propagation. Or, the breeders can graft, or attach, a piece of the seedless grape variety onto a healthy vine base, called a rootstock. Think of it like this: When someone cuts their hand, a doctor sews the cut together, and the two pieces heal as one. The grafted vines grow together the same way. And, the grape variety attached to the rootstock keeps producing delicious seedless grapes. http://extension.osu.edu/~twig/plants/html/102297.html Mar 20 06, 9:36 AM

Basically, it's just like navel oranges or other seedless fruit. Mar 20 06, 9:43 AM

Same applies to bananas and there's trouble brewing there. Bananas are all seedless now. OK, there are the ones called plantains, but you wouldn't want to eat them uncooked. And the stock that they take the cuttings from is getting weaker. Loads of research going on, but if it doesn't get results no more bananas sooner or later. Mar 20 06, 11:15 AM
