The determinant sort is what does it mean?

A variety is a variety of plants that have the same characteristics and properties. Usually such plants are bred by breeders as a result of laborious long-term work. The resulting variety is a plant with stable characteristics.

As a result of the work of professionals in the field of crop production, various hybrids were obtained. They are obtained by crossing several ideally matched parent plants, resulting in new varieties with improved qualities. One of the most frequently crossed plants are tomatoes. As a result of painstaking work, it was possible to obtain a variety of hybrids, determinant, semi-determinant, indeterminate varieties, and stems.

Determinant varieties

Many novice truck farmers are interested in the question, the determinant tomato variety - what is it? Determinants are called tomato varieties, which limit the growth of the bush at a certain height after tying a number of brushes with fruits. All varieties of this group can be divided into hybrids, varietal tomatoes, early, medium, late, stems, sredneroslye.

Shtammy species

Stamp tomatoes differ from others in low growth (not more than 50 cm) and thick stalk. They are considered the earliest. Usually such plants are grown through seedlings planted in the soil at the age of 40 days. The first fruits from the burs are harvested 90-95 days after emergence.

A feature of the deterministic species in their bookmark brushes. Usually varietal plants and hybrids first brush are laid through six leaf pairs, subsequent brushes appear every two leaves.

Medium-sized, or semi-determinant

A medium-sized variety is a kind of determinant tomato, for which the height is 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 jungles in greenhouses, are well ventilated.

Ideal species

The variety is the biology of the species, allowing to obtain new plants with the best qualities, high yield, resistant to various diseases and capable of developing under different conditions.

For the greenhouse cultivation, the ideal 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 ideal varieties can grow without restrictions and reach a length of more than 4 meters. In a separate category, a tomato tree will follow .

Harvested varieties of determinant tomatoes

To obtain a large crop in the open ground in conditions of risky farming, it is better to grow low tomatoes. They are distinguished by a friendly yield of crops and a short vegetation period. Some of the best representatives of low tomatoes are:

• "Rio Fuego" - a hybrid with a maturity of 100 days;
• "Twist" - varietal tomato, obtained by the Russian breeder AA Mashtakov;
• "Roma";
• "Andromeda";
• "Agatha";
• "Gift of the Transvolga" - a low plant for open ground, able to adapt to any weather conditions;
• "Volgograd early-maturing" and others.

These species are distinguished by good yield, deterministic type of development of the bush, resistance to diseases, but they have different maturation periods.
