I know they continue to grow them commercially, but if they got them from some kind of mutation, wouldn't they die out after one generation?

seedless oranges and grapes can be reproduced by grafting..........

How stuff works:
How can there be seedless grapes? How can they reproduce?
Some come from cuttings
http://www.howstuffworks.com/question349.htm
Seedless fruits can develop in one of two ways: either the fruit develops without any fertilization (parthenocarpy), or pollination triggers fruit development but the ovules or embryos abort without producing mature seeds (stenospermocarpy).......

Grapes are really a vine, which is an angiosperm. It's reproductive strategies involve manifesting flowers which have pollen and all the other needs for reproduction like anthers and so forth. Then the flowers can either be pollinated by say a bumblebees for instance transferring genetic material from one grape vine to another, or the pollen could be carried by the wind to another of it's same species. If the seedless vine still produces flowers it can spread pollen to a vine that does produce seeds and that way produce progeny. Without seeds it would be akin to a mule. Mules are sterile I believe and cannot reproduce. With orange trees it is much the same concept.

Most of them are bred that way. For example, you take two species of grape that are "normal" grapes and cross-pollinate them. The resultant hybrid may have better tasting grapes. (This is how a mule is made. Horses and Donkeys can reproduce, but a mule is sterile. So you have to make mules by always mating a horse and a donkey.) You can also take pieces of the vine or pieces of branch from an orange tree and root them or graft them onto the trunk of an existing plant.

Seedless oranges are reproduced with a process called Parthenocarpy. Grapes are propogated with cuttings.

With maximum of them you're taking cuttings from the plant, they do no longer reproduce 'clearly'. some end result only have seeds while the plant is pollenated, the seedless ones are only unfertilised.

There is no such thing as a seedless orange or grape...the seeds just havent developed yet. Or in some cases the ppl. modfy the tree genetically so that the seeds are not produced.

In a nutshell, they're cloned.
They take grafts from the mature plant.

I believe they grow from cuttings.
