How do you get seedless grapes?

Question

Yeah obviously you buy them, but how are they produced Genetically

Answer 1

My God - seven prat answers - the question was HOW, not WHERE--------

However - they are specially grown after years of scientific/botanic experimenting between the various types so that this seedless one is the result of many years' research. and are reproduced from root cutting as well as stem cuttings.

Answer 2

As I expect you got already - grapes are fruits and therefore need to naturally contain seeds because the point of the plants putting all this energy into making a fruit is so that animals will eat them and disperse the seeds. So seedless grapes (and other fruits) are not generally found in nature.

Fruits that we buy without seeds (eg. grapes, bananas, clementines etc.) have a genetic condition called polyploidy. This can be induced through natural mutation, radiation treatment (of seeds before planting), or genetic engineering. The fact that they are seedless means that obviously we can't breed for this trait through conventional breeding because that requires seeds to be planted to grow the next generation! The plants contain several copies of all of their genes. This enlarges their fruits and makes the plants sterile - ie. unable to reproduce through seeds (because of the problems of combining DNA from two individuals with massively different amounts of DNA), so their fruits are also seedless.

Answer 3

I think the question pertains to whether seedless grapes are a genetically modified crop - the answer is no. They're bred just like, as was said, black tulips, or dairy cows or golden retrievers. The same process humans have been using for thousands of years. And the bit about cuttings was right, but that's not unique to seedless grapes - that's how basically all grapevines are propagated.

Answer 4

What idiots! one answer of from the shop could have been funny but talk about over doing it!

They are genetically bred like how they make black tulips and blue roses etc. Slowly they take varieties with few seeds and cross pollinate them until the grapes they produce are seedless.

The bit I don't get is how do they then produce more? I think they must take cuttings or something.

Hope someone that actually knows a thing or two answers this question properly for you.

Answer 5

Scientifically a growth hormone called cytokinenin is sprayed on plants .That hormone induces the seed less fruit formation in all seedless fruits

Answer 6

go to the grocery store's fruit section and look for "seedless grapes". Select how many pounds you want, then take them to the register and purchase.

Answer 7

You go to the supermarket, pick up the grapes, go to the checkout and pay. You can then eat them...

Answer 8

i guess go to the grocery store. eat dem and check out weather dey r seedless or not...
dats it i guess!!!!!!

Answer 9

go to the grocery store.
