The heirloom tomato, Marglobe, was developed in 1917 by Frederick J. Pritchard of the United Stated Dept. of Agricuture. He crossed the Globe and Marvel tomatoes. Thus the two names into one, Marglobe. In 1925, it was publicly released.
The Marglobe is a determinate tomato and is very productive. This means that it will produce its whole crop in a short time. Therefore, it is an excellent canner because it production is not spread out over many weeks. It produces very round, red-fleshed tomatoes, averaging 8-10 ounces in size. Some may be larger. Marglobe heirloom tomato is very tasty. It is an excellent slicer as well as canner.
We like it because it does not have a deep core, and it seldom cracks. So it is much easier to prepare for canning. The flesh is firm and it produces well.
