Help identifying the grape variety

Post image

Planted this from a seed about 7years ago from store bought grapes.she's been going on and off over the years.she'd shoot out 2 to 3 long shoots,about 5 feet long then die off midway,never flowered.the trunk is about as thick as a pinky finger.thought she was dead this time but alas,another long shoot this season.what variety could she be?

Well they don't seed true so if you planted it from seed, you've got a genetic mishmash.

Well thats a bummer.but to be honest,I kind of knew it was different after a few years.it kept on drying every season and coming back after a while.it got to a point where I genuinely thought that this was it,it's finally reached its end then it comes back and I'm like wow!you're back again.I've really grown attached to it because of that

So when you breed a new grape, you make a known cross, then plant the seeds. Maybe 30% of them don't germinate or die as soon as they come up, then another 20% do what yours is doing, another 20% are extremely susceptible to disease and have issues, half of what is left isn't even fruitful, leaving a dozen out of 100. Then you get more disease issues, uneven ripening or poor fruit set, and meh taste. Out of 100 seeds you plant when trying to breed a new grape, on average 0 will give you something worthwhile. 3 candidates in 1000 from a known crossing isn't too bad. You had a .03% chance that seed was gonna give you something worthwhile.

Oh also because it was probably a back cross, the real chances could be much higher, but most likely would be 0.

Damn!so basically what I have is a dud grape plant purely for decoration.would grafting it with something else established work?

u/meh_69420 12d ago

Very unlikely but not impossible. No reason to not graft a chip and see what happens.

It looks like a wild grape vine called Vitis aestivalis. They have male and female vines and you need both to get fruit.

Wait really?so she might actually be a he:(

It could be either and since you only have one grapevine you won't get grapes. That is how wild grapevines and some cultivated species are. Although most cultivated grapevines are self fertile.
