Tomato Varieties

There are over 10,000 known varieties of tomatoes. All those choices make selecting the ideal tomato interesting and fun. As you try to decide on the type or types of tomatoes you wish to grow, there are several considerations you will want to keep in mind. Some of the major considerations are:

  • Productivity
  • Tendency for fruit splitting
  • Disease resistance
  • Climate

Definitions

Here are some terms that you will come across as you learn about tomatoes.

  • Hybrids: produced when one type of tomato is crossed with another type to produce a new type with mixed characteristics. Hybrid seeds must be purchased every year because seeds from a hybrid plant will produce varied offspring with different characteristics from the parent.
  • Heirloom tomatoes: are self-pollinators that have bred true for 40 years or more. That is, an heirloom tomato will continue to produce tomatoes of identical characteristics from generation to generation. Heirloom is analogous to “pure-bred.”
  • Cultivar: Cultivated variety of plant that has been selected for desirable characteristics such as color, form of flower, yield of crop, disease resistance, etc. When propagated correctly the plants retain the special characteristics.
  • Determinate: or bush type bear full crop all at once and top off at a specific height. Good for container growing. Good for home growers who are interested in canning.
  • Indeterminate: or vines continue to grow in length and continue to produce tomatoes until killed by frost. Good for gardeners who want ripe fruit throughout the season.
  • Semi-determinate: top off like determinates but produce a second crop after the first crop.
