I haven't grown most of them, and I don't know how well any of them tolerate wet conditions, but some hybrids that I think might be interesting to grow include these:
* Chef's Choice Pink F1 (AAS award; F, A, N, TMV, Crack and Scab—it is supposed to be anthracnose-tolerant, whether or not that's what the A stands for; anthracnose can cause fruit rot—there are only a few known tolerant tomatoes)
* Gurney Girl's Best F1 (VFFTTyTsw. 75 days. Gurney's talks this tomato up a lot.)
* Heatwave II F1 (VFASt; 68 days)
* Tycoon (I don't really know if this is a hybrid, but it's disease-resistant enough to be one: VFNTSWV; 80 days)
* Beefmaster F1 (Alternaria Alternata (Crown Wilt), Fusarium Wilt Race 1, Root-Knot Nematodes, Stemphylium (Gray Leaf Spot), Verticillium Wilt; 80 days)
* Early Girl VFF F1 (I like and have tried Early Girl (not sure if it was the VFF version), but I'm not sure how it performs in Pennsylvania.)
* Celebrity F1
* Fourth of July F1
* Juliet F1
* Pink Girl F1
* Celebration F1
* Big Beef F1
* Brandy Boy F1
* Big Boy F1
* Park's Whopper CR Improved F1
* Red Brandymaster F1
* Pink Brandymaster F1
Even though it's not a hybrid,
Napa Giant looks like a great, productive tomato. You can get a lot of pounds of fruit off of it. It's a selection from Mortgage Lifter that is larger.
For open-pollinated tomatoes that it sounds like withstood a hot, very wet year in Florida,
see the first post in this thread.
