Yes. Several years ago, I grew two plants from F2 seeds from Jet Star and got nice red tomatoes in two different sizes. One plant gave consistently larger tomatoes than the other. Both had decent flavor, and both had more ruffled shoulders than the F1 hybrid tomatoes.
The following year I grew two plants from F3 seeds out of the larger tomatoes and got essentially the same results. I never followed up with F4s or beyond.
