They are propogated by cuttings. Most grapes are, actually. Obviously, new varieties (including 'seedless' ones) have to have come from a seed but for general propogation (as in planting a new vinyard of a known variety) it is done by cuttings.

'Seedless' grapes do have the occasional seed, however. It's just that most of the flowers are sterile. The proportion of seeds is very low, however, and there is no guarantee that, if planted, they would come true to type.

Grape breeders create new seedless vegetation by potential of putting the pollen of a seedless grape onto the flowers of a grape type that has seeds. They then decrease open and look on the fruit of each and every plant that grows from this tournament. The breeders are searching for seeds -- some vegetation could have seeds of their fruit and others won't. whilst they arrive across a plant that has no seeds, or according to probability in simple terms has very tiny lines of seeds which you will not be waiting to style, the grape breeders use it to make extra seedless vegetation. one way is to diminish off small products of the seedless plant's vine and place it especially growing to be situations in a greenhouse. at last, the products of vine will advance roots and become new, individual vegetation. this methodology is termed propagation. Or, the breeders can graft, or connect, slightly the seedless grape type onto a healthful vine base, referred to as a rootstock. think of of it like this: whilst somebody cuts their hand, a doctor sews the decrease collectively, and the two products heal as one. The grafted vines advance collectively an identical way. And, the grape type related to the rootstock keeps producing scrumptious seedless grapes.

I have not one idea, but it is a wonderful question. and has made me smile. On the other hand, ....no clue at all. Maybe they get the seeds from the grapes that are not seedless, plant them, but do something wierd to them first, like mutation or something, so the new grapes come out without the seed, like a missing gene or sommat....just a guess, but a nice question.. almost a conunderum.

Seedless grapes, are grown from a seedless parent plant .

By cuttings

which can be grafted ,onto a vigorous growing root stock
( this speeds the process up)

or by tissue culture , grown on an agar plate , in a laboratory.

Hardly any fruit is propagated by seeds, so in the case of seedless grapes it doesn't matter. They are planted using cuttings.
Although it is very easy to grow some fruit from seed, such as citrus and avocado, the likelihood of the plant bearing much fruit and then of edible quality is slim.
So it is either rootstocks or cuttings.
Don't know why, but there you go!

Seedless grapes kinda do have seeds in them - the most solid bit in the middle is the 'seed', so if that's planted, then the fruit can continue growing.

They're called seedless because the 'seed' bit is so soft - it makes no difference when eating the fruit.

Seedless grapevines are grown by planting stems broken off older grapevines.

They are genetically modified. So the initial seed comes from a plant that is GM, and changed so it doesn't produce any second generation seeds.

Similar to F1 Hybrid plants you get frm a garden centre where they will not propagate, although in this case it more to do with them protecting thier copyright and sales.

they are specially grown so they dont have seeds

cant they cut bits off and plant them people do it with backcurrants
