Hybrids for hobbyists

What about F2, F3 etc. Do they typically produce spitters or they are just some other form of tomatoes but resembling the F1 but still is not a spitter?

Shule,
What is a “sport” that’s a new one to me.

A sport is kind of like a mutant. If you grow a Sweet Cherriette tomato that produces as usual, and then suddenly it throws a medium-sized bicolor beefsteak with anthocyanin, it's probably a sport. If all the fruits are like that, it's probably the result of cross-pollination (unless the parent was a sport). Sports (maybe not 100% of them) can breed true, without any need for stabilizing them over generations.

As I understand it, GGWT never needed to be stabilized, and I was under the impression that there was only one fruit like it that year. I could be wrong on both points, but that was my impression, based on the things I had read.

Q: Do they typically produce spitters?
A: I don't think so.
