I am also de-hybridizing various blight-resistant ones -Iron Lady, Ferline. Losetto, Crimson Crush, Cocktail Crush.
A fawn managed to squeeze itself into my deer-proof area and eat the tops off them all. I still haven't found the place where she is getting in but I will dig up what remains of the plants and plant them in my greenhouse, hoping for tomatoes from them in the winter.
