growing out rootstock

[beeman]

Seems no body answered the original posting.
Has anyone grown out root stock, saved seeds, and then grown them out again?
Presumably to try save the high costs involved in producing root stock?
Anyone?

That is a very interesting concept! Check out some of Delerium's threads. He did several stacked graft experiments, but I believe it was more for multiple varieties as opposed to what you are suggesting. I have not read or heard of anyone trying that. D does have a thread on indeterminates using dwarfs as rootstock.

Beeman,
Garrett indicated he was going to try it.
If they are really F1 hybrids, the seeds for the F2 will be all over the place with characteristics and while some might come close, you really won't know what you are going to get in terms of resistance characteristics, etc. You would have to grow them out and be willing to sacrifice plants to see if they provided the necessary resistance.
I know I read someplace about Maxifort being grown and then regrown to confirm it was a real F1. If I am remembering right it was Dar (Fusion Power).

The use of an interstem is common practice in apple grafting. For ex: using a rootstock known for strong/resistant root systems, then an interstem for dwarfing, then the scion for desired fruit properties.

Are you going to give it a shot for tomatoes?

I grew out a Supernatural last year with the intent to save the seeds.

The plant produced a relatively good tasting salad tomato, but not a lot of them.

But I did not have success grafting with Supernatural (probably entirely my fault) and the plant I grew out didn't seem to do any better as far as disease resistance or vigor than my other plants so I ended up not replanting with the saved seeds this year. This year I decided to try Maxifort root stock.

Maybe I will experiment with this next year, but for now my space is maxed out...unless I hear very positive feedback on the Thessalonica post, in which case I might consider squeezing in just one more plant. However, the key in such a graft would be to do it early enough to first let the interstem/stock graft time to heal before doing the final interstem/scion. This used to be something of a standard approach with apples before better rootstocks were found.

I made room for several supernatural and estimino plants in my container garden since i had no more room in my rows. Im kind of making it my mission to grow these out so i guess i will see what i get..... eventually. All of the plants i have are flowering normal so thats a good sign.

So i picked 5 supernatural tomatoes so far and all were spitters. Pretty much hard and mostly meaty. Im fermenting the seeds and will attempt to sow some here in the next week or two. I will see what kinds of fruit the F2 puts out in the near future. As for the estamino it has only had a couple of flowers all of which never set fruit .

If I ever get the time, I would like to use some standard OP varieties that are known for their sturdiness and growth and see what kind of root-stock they would make. I am thinking of Mong, Granny Cantrell's German Red and Roger's Best Black, all of which have produced massive plants for me. I had a GCGR once that was 15 1/2 feet long, by season's end.
