look at THIS reply, to same post in Cooking and Baking:

5. I have had good success in my area planting Russian tomatoes.

The version is called black Krim, and it is from Crimea. The plant produces well into October/November in the Chicago area and the taste is quite good.

A year or so ago. It's very good

not for flavor. On top of that, most tomatoes are picked green so they have a longer shelf life and never get the chance to develop the full bodied taste that comes from a vine ripened tomato.

Also makes it easier to pick mechanically when the tomato is a uniform shape and hard as rock. I never buy tomatoes from the supermarket. I can get the real ones from May till about September, and there is nothing better.

grow heirloom tomatoes!

I had great results for several years with Abe Lincoln heirlooms, until late blight found my garden and wiped them out one year. I worked up another garden plot on the opposite side of my yard a hundred yards away, and a couple years later the blight made it over there. It took a couple of years before I found another heirloom that yielded as well in my soil and was blight resistant.

Other varieties have had cracking issues when the moisture levels are less than optimal, or had fruit that could be was under-ripe Friday, perfectly ripe Saturday and Sunday, and a soggy mess by Tuesday! Clearly not acceptable for commercial applications.

on a plate is pure heaven. So many different flavors dancing around on your tongue...

Picking them Green and refrigeratoring it the genes won't matter

You can order seed here for a donation to their research program: http://hos.ufl.edu/kleeweb/newcultivars.html

All in all, I thought both varieties had very good flavor, though I preferred the Garden Treasure simply for the fact it was larger in size. I saved seed and plan on working with it for the next few years to develop my own stabilized lineage like I did with some watermelon hybrids I created a few years ago (ever seen a Sugar Baby watermelon crossed with a Moon and Stars watermelon?).
