Disease Resistant Vs Taste Update Bad Photos

[Nyboy]

I was caught up in finding the most disease resistant grape for my area. I choose Mars and Jupiter planted 4 of each. One of the vines produced grapes this year ( labels where removed) The grapes where small, sour, and full with seeds almost wondering if was wild grape. I don't make jelly was looking for table grape, hope the other vines taste better.

I'm wondering if instead of the variety you thought you were getting the vine died back and you got the root stock?

Oh I didn't realize grapes where grafted. I was wondering if vine died and wild grape happen to grow in same spot. Yard and woods filled with wild grape.

Those are both seedless varieties so I think Ridge is right in thinking you've got the root stock.

I can't think of any reason for a grafted grape other than borderline hardiness in your area. Grapes are too easy to start from cuttings. I've shipped a few vineyards worth of grape cuttings to different parts of the U.S.A. with no problems getting them growing.

It is probable that grafted grapes would be on wild grape stock so it is possible that your grape plants died back. Just not something I've ever heard of around here.

Okay, research shows grapes are frequently grafted onto wild grape roots in order to prevent a root disease (phylloxera) but mainly to get fruit production sooner than from started cuttings alone. Mars is rated at zone 5-7 hardiness so it is possible that the grafted stems didn't survive a colder than normal winter.

It is also possible that bird droppings with wild grape seed, underground growth from wild grapes growing nearby hit upon a 'safe' place to grow, or even that a few stems grew up from the rootstock. Are all the vines coming from the plant the same tiny, seedy variety or could some still be too young to set fruit?

Finally, you have been in a state of drought for much of the summer. That will often result in smaller, seedier grapes of any variety. Did the plants get enough water throughout the growing season?

Mars are supposed to be a seedless variety and according to my research, seedless grapes do tend to be smaller than their seeded cousins despite what catalogs say. My seedless Concords are about half the size of the standard Concords I am grow.

Do you remember if it was Mars or Jupiter vines that fruited? I didn't check out your Jupiters. Leaving that for you since they would have been more reddish than wild-grape blue in color.

I am really starting to think rootstock. Sprinkler system made sure vine got plenty of water. Grape had LOTS of seeds was dark purple. my nephew's girlfriend thought she was helping one day and removed all tags from plants in garden

Went up to house after work, was getting dark lens kept fogging up. Root stock, Mars or Jupiter?

I have a feeling the rose next to it is wild also

Mars is the color of Concord grapes and like Concord has a slip-skin. Jupiter is more of a red grape.
