Awesome to hear you're making so much progress with this cross, Mark.
It's fantastic that you can grow so many plants, and even get two generations in a year.
Also brilliant to produce more F1 seed, since it's such a good one.
I was hoping to try your F1 this year, but my resources for growing are tenuous and I had to scale back my tomato starts, knowing that the plants may end up with nowhere to go.
Re: selecting for earliness - in my crosses here, I selected for early flowering first in the F2, and hoping to find the combination of desired traits somewhere in the 'early' pool of F2's. I had the impression that earliness does segregate out in the first couple of generations, but I may be wrong. Another option is to make crosses between generations or siblings down the line, to try and recapture the full package earliness/size/texture/taste. I know it's difficult to get larger fruit that are early - and why they're hard to find! - but for certain you have the best chance to do that with such a large grow out. Very exciting project for us short season folks.
Best of luck with your season, and I look forward to your updates!
