Severnaya Malyutka

Very early (less than 100 days from seed) round, bright red tomatoes (just about 2 ounces) are borne on a short, stout plant with RL finely-divided, almost feathery foliage.
This would make a good container plant I think, though they produced a large crop for me in the field and went well into the fall. The photo was taken early, they were continuously producing dozens of tomatoes each week. Not prone to cracking or disease, either.
