Indeterminate

Large and very large fruit can not be formed on a small, low bush, you need a tall and powerful plant.

Only indeterminate tomatoes, those whose potential is great, the power of growth is mighty, and the shoot has unlimited growth (until you stop it yourself) can strike with tomato fruits of amazing size and taste.

Disadvantage of these varieties and hybrids there is that they need to be formed (stepchild) and tied up constantly, and supporting structures for a tomato to build reliable and strong ones that can withstand the enormous weight of tomato fruits.
