A variety is a variety of plants that have the same characteristics and properties. Typically, these plants are bred by breeders as a result of years of laborious work. The resulting variety is a plant that has persistent traits.
As a result of the work of professionals in the field of crop production, a variety of hybrids were obtained. They are obtained by crossing several perfectly matched parent plants, resulting in new varieties with improved qualities. One of the most commonly crossed plants are tomatoes. As a result of painstaking work, we managed to get a variety of hybrids, determinant, semi-determinant, identical determinants, and fungi.
Determinant Varieties
Many beginner gardeners are interested in the question, a determinant variety of tomato - what is it? Determinant called varieties of tomatoes that limit the growth of the bush at a certain height after tying a certain number of brushes with fruits. All varieties of this group can be divided into hybrids, varietal tomatoes, early, middle, late, standard, mid-growth.
Stamp types
Stem tomatoes differ from others in low growth (not more than 50 cm) and a thick stem. They are considered the earliest. Typically, these plants are grown through seedlings planted in the soil at the age of 40 days. The first fruits from the stems are harvested 90-95 days after emergence.
A feature of the determinant species in their bookmark brushes. Typically, varietal plants and hybrids put the first brush through six leaf pairs, subsequent brushes appear every two sheets.
Mid-growth, or semi-determinant
The medium-sized variety is a type of determinant tomato, which is characterized by a height of 120-150 cm with the possibility of forming a bush in two stems. All other stepsons are deleted. Such plants take up little space, do not create the jungle in greenhouses, and are well ventilated.
Indeterminate species
A variety is a species biology that allows you to get new plants with the best qualities, high yields, resistant to various diseases and capable of developing in different conditions.
For greenhouse cultivation, ideally terminating varieties are better suited. They are not limited in growth, bear fruit for a long time. Such plants form in one or two stems.
The indeterminate varieties can grow without restrictions and reach a length of more than 4 meters. Tomato tree should be included in a separate category .
Harvest varieties of determinant tomatoes
To obtain a large crop in the open field in conditions of risky farming, it is better to grow low tomatoes. They are distinguished by a friendly return of the crop and a short growing season. Some of the best representatives of low tomatoes are:
- "Rio Fuego" - a hybrid with a maturity of 100 days;
- “Twist” - varietal tomato obtained by Russian breeder A.A. Mashtakov;
- "Roma";
- "Andromeda";
- "Agatha";
- "Gift of the Volga" - a low plant for open ground, able to adapt to any weather conditions;
- "Volgograd precocious", etc.
These species are distinguished by good productivity, a determinant type of bush development, and disease resistance, but they have different ripening periods.
