I'm taking 25 or so OP cherry tomato varieties this year and planting out in a large block hoping for some interesting crosses to find the following year. I've been fairly interested in what Brad Gates has done at Wild Boar and from what I've read this is how he got started.
Does anyone have any tips to help make sure that these cross so that I can get a more that 2-5% chance of some crosses happening? I also have a wild currant tomato in the mix.
Should I bother rubbing flowers together from different plants or just let nature takes its course?
I'm interested in Native American varieties that may have been grown in the New England area, specifically MA. Please message me with any information.
Joseph Lofthouse has some neat information about this in some of his threads here and elsewhere.
Some tomato varieties have an exserted stigma and naturally get more cross pollination.
This can be variable, but I've had a little luck with a not quite stable cherry tomato called Blue Ambrosia and sometimes this occurs in Sungold F1 and its segregating and OP descendents. I suspect but am not certain that Blue Ambrosia is sungold descended.
Joseph has a saladette size or better tomato called Big Hill that also does this.
With 25 varieties there is a chance one will have this trait. If so, grow out more seed from any variety exhibiting the trait.
Beefsteaks often have early season double and triple blooms, these will out cross at a higher rate.
Even if not intentionally crossing you can help things along by dusting pollen around onto exserted stigmas if you want.
Joseph's half wild tomatoes may have a higher incidence of the trait as well.
Include some potato leaf varieties. Some have the trait, but also any hybrids with regular leaf varieties will have regular leaves and you can grow out thousands of seedlings in a flat.
Also organize tomato varieties so as to maximize cross pollination. Close together. Put varieties with easy to distinguish traits close together. Alternate yellows and reds. Potato leaf and regular leaf for instance.
I did something similar and I got most crosses from Blue Ambrosia and just a few from potato leaf varieties.
However even one cross is going to segregate quite a bit, especially if the parents are very different.
I like Brad Gate's stuff too. His Amethyst cream cherry is high on my list to cross with something.

I don't know about crossing rates, but of cherry types, the "centerflor" types from PEACE SEEDS And Alan Kapuler are interesting. My favorite currently is a Solanum Cheesmanie (hybrid, though they won't admit it) being sold by terrior seeds. It has an Awesome bushy growth habit and produces tons of tasty yellow fruit. It is nearly as tasty as sun gold to me, and more productive and wild which I like.
