Is there any possibility of getting a rooted cutting of "the one" shipped? 
Do you think the flavor is stabilized? Will seedlings this year change in flavor?
Nothing to cut off yet! I wish I had dug up the original and brought it inside.
I hope to find out the answer to the flavor stabilization questions this year. My guess based on the flower structure of the mother is that selfing will be only part of the offspring. So I expect better average flavor but would be suprised if they all taste good.
I am also curious about the range of growth forms. Some of the seedlings seem really slow growing. Others faster to pretty normal but the oldest is definitely growing fairly slow and sturdily.
Little pumpkins had a similar flavor. Will see what it does this year. A cross would probably be a little boring but I am most interested in the first question for now. Stability?! Little pumpkins produced far less seed and had inserted stigmas. I don't know for sure if that has any advantage for stability. I thought I might keep them in the same block but I've also thought about putting the Little Pumpkins in with a wider diversity.
I wouldn't be suprised if it takes awhile given that we have deliberately bred for outcrossing. So more like breeding corn and less like breeding inbreeding tomatoes. Selection still works though. I think pulling three good ones out of hundreds this year I would be very pleased if 60% of these are good. If ten of them are that is still progress. Planting them in more places may help to understand the variation as well. My soils are a bit variable.
I would like to grow the "Persimmon" named tomato some time. Don't think it would do well here with the short growing season but I might get one good tomato. I am not actually calling mine exactly the same name- I don't actually think it is ready to be named or distributed to the general public. The tag description in sloppy handwriting is actually "The One, Fuyu Persimmon, Exserted, Open".
One of my questions this year is if I have really tasted very many really good tomato varieties. I'm curious to know what some of the dwarfs and Craig's top ten list tomatoes taste like. I am also growing a clump of F1 Sungold because it is one I have tasted and is sort of a similar fruity flavored tomato.
