It seems that every tomato volunteer is a cherry tomato - don't know if you have ever noticed that. I found out that if you grow from Burpee seed packs they breed with clones. You are getting a first generation seed or starter plant (think S1) that has a specific mom and a specific dad that have proven to produce specific seed-plants.
Like if you get S1's that are pretty homogenous, one backcross and the ghosts of Christmas past all come out. Most of those walmart tomatoes are gonna make cherry tomato S2's. I think they use them to get 'prolific' in the mix but it's also a dominant gene plant. And "making an S2" just means you grew tomatoes and they had seeds LOL
Even if you grow heirloom tomatoes, unless you only have one variety they can cross and you end upwith wierdness.
Pretty sure that's just for tomatoes though.
Yep they cross if they are open pollinated, I think most heirlooms are.
I've been saving seeds from Baker Creek Cherokee purple and Black from Tula and they definitely crossed, I had some Tye Dyed greens growing the 2nd year this year one plant had all 3 characteristics and they are getting acclimated to the environment here too. On my fourth Generation now.
I like variety and saving seeds so they cross. I'm kind of excited to see how some of the peppers turn out next year. Saved seeds from banana peppers, Serrano, and King of the north, all of them were in the same 200 gallon pot so I know they crossed. The peppers did good this year.
Yes I have had volunteer turn into cherry tomatoes never thought much about it though since I was composting lots of different things at the time, Interesting about the Burpee breeding.
