Where do seedless grapes come from?

Question

Yeh, I know, Sainsburys. No, I mean, if they dont have seeds how do you grow more?

Answer 1

Seedless grapes actually do contain seeds at some point. But a genetic error prevents the seeds from forming hard outer coats like normal seeds do

Answer 2

If you go to a grocery store today to buy grapes, there is a good chance that the only type of grape you can buy is seedless. Nearly all grapevines in production today produce seedless grapes.
It turns out that most fruits today do not come from seeds. They come from cuttings instead. This is true of grapes, blueberries, apples, cherries, etc. (pretty much all fruits except citrus, although scientists are working on that, too). A piece of a vine or branch is cut off, dipped in rooting hormone and then placed in moist dirt so that roots and leaves form. Because they come from cuttings, new grapevines are essentially clones of the vine they were cut from.

Answer 3

The seedless variety of any fruit, including oranges comes from a genetic mutation that would normally be a dead end because as you say there are no seeds to reproduce from. But someone thought seedless might be a good selling feature, so you take a small cutting of the grape vine and graft it onto a regular grape vine. That vine will continue to grow and make seedless grapes.

Answer 4

No problem. You can't grow from seeds because the vines are sterile hybrids selected specifically to be unable to set proper seeds. If you know someone with a vine you can take a cutting, but it'll be years before you get any grapes - but you can buy them online from a few places. Here's the fullest one I know, but you may find the same varieties cheaper elsewhere once you know what you want. Good luck!

Answer 5

I asked this question about 5 months ago and the best answer I got was this.....They interbreed grapes until they get one with no seeds and then they take a cutting and graft it on to a seed bearing vine and hay presto the bugger grows and hay ho, seedless grapes.

Answer 6

They come from genitically engeneered seeds. Seeds there were designed to be steril so that the grapes will not have seeds. This makes the company that produces the seeds a lot of money since people have to come back to them for more seeds when the plant dies.

Answer 7

They come from the same place virtually every living thing does--a seed. Regualr variety (seedful?) produce must be grown to produce seeds that are then modified to grow seedless produce. The seeds from seedless produce cannot produce a plant.

Answer 8

Asda also!
I have found many a seed in my seedless grapes, and ignore that harry, grapes grow on vines! i think that all grapes have seeds, but they are so small that you dont notice them.

Answer 9

They come from regular grapes. They are dioecious,meaning they have male and female plants. If the flower remains unfertilized, no seeds grow in it, only fertilized flowers grow seeds. Many plants are like that, including marijuana, which is where the term sinsemilla (seedless)comes from

Answer 10

I think they are grown from special cuttings and cultivars bred to only produce one generation.

Plant genetics are interesting. Take two plants with a recessive for "no seeds". Those two plants are pollinated and make seeds.

But the plants from those seeds will be seedless, and won't make another generation of plants.

That's my best guess.
