Tomato Seven forty F1: characteristics and description of the hybrid variety with photos

What does a tomato variety and hybrid mean, what is the difference

A variety is the result of many years of selection and reproduction of the most productive and stable parent pairs of plants.
Varietal crops retain their properties in the next several generations. Seeds of any variety can be grown independently; they repeat the parental characteristics. Perhaps this explains the huge (most likely incalculable) popular selection of tomatoes. On seed packets, next to the name you can see the designation F1. This suggests that this is not a variety, but a hybrid form. The abbreviation is easy to decipher:

F – the first letter of the word children (filii); 1 – first generation.

Hybrids are obtained by crossing specially selected plants of different varieties. An F1 tomato hybrid occurs when you have two tomato plants of different varieties, and then one is pollinated with pollen from the other variety. The seeds of the resulting cross-pollinated tomato will produce plants that are F1 hybrids (first generation hybrid). The descendants of F1 hybrids are F2. The descendants of F2 are F3 and so on. Hybrids are more productive and of higher quality than varieties, but retain their properties only in the first generation. There is no point in collecting seeds from hybrids. They do not repeat the original qualities, and most often grow up much worse than their parent pairs.

Hybridization requires protected soil and manual labor, so the cost of such seeds is higher than varieties.

To debunk a myth that we sometimes encounter, let us remind you that F1 hybrids are not genetically modified. These are completely natural plants, bred in the traditional way.

Advantages of a hybrid

Tomato Seven forty F1 belongs to the first generation hybrids. The variety is intended for cultivation in open ground conditions, film greenhouses. An early ripening tomato begins to bear fruit 95-100 days after germination.

During the growing season, the determinate hybrid reaches a height of 70-90 cm. The first peduncle is formed at the level of 5-7 leaves, and subsequent ones are formed at intervals of 1-2 leaves. The inflorescence is simple, 5-7 fruits ripen in the cluster.

The description of the 7/40 variety is associated with the characteristics of the fruits being round in shape. In the ripe phase, tomatoes acquire an intense red color. The stalk has no green spot. When cut horizontally, many chambers with seeds are observed.

The fruits have smooth skin, dense pulp, intense tomato aroma and taste. The fruit weight reaches 220-250 g. The crop yield is 15.5-16 kg per 1 m².

The hybrid is resistant to most diseases of nightshade crops, including Alternaria, blossom-end and root rot, and tobacco mosaic virus. In cooking, the fruits are used fresh, for preparing various dishes, and pickling.

Black varieties of tomatoes in greenhouses

In the middle zone and in the northern regions, the cultivation of these varieties is possible only in closed ground conditions, but in the southern regions of Russia, greenhouse varieties with an average ripening period are available for cultivation without shelter. In case of unfavorable weather conditions during the season, there is a risk of weight loss in large-fruited varieties.

What to fear

Tomatoes are susceptible to pests and diseases. Pests rarely attack tomatoes, but spraying them with special solutions will help protect your plant. You can buy them at any department store.

The main danger to tomatoes is disease. The most common are: downy mildew, leaf spot, tobacco mosaic, blossom end rot. But don’t be afraid: the new seven 40 tomato hybrid is resistant to the listed diseases, and nothing threatens your harvest.

Growing and care

Seeds of Minusinsk tomatoes are not recommended to be sown directly into the ground. They need to be grown by seedlings to achieve good germination.

It is recommended to prepare seedlings 60 days before transplanting plants to a permanent place of growth. To grow seedlings, special deep boxes are used. It is better to take universal ready-made soil. The soil temperature should not be below +22 degrees, otherwise the seedlings may die.

In the open ground

Seeds for seedlings are sown in early or mid-March.

To grow young viable plants you need:

Properly prepare seeds for planting. To do this, they need to be placed in a cloth moistened with warm, clean water for a day. Prepare the soil for seedlings. If you use a ready-made mixture from the store, just bake it in the oven

It is important that its temperature is not lower than +22 degrees at the time of sowing the seed. If you use soil collected from your own local area, pre-treat it with a weak solution of potassium permanganate for the purpose of disinfection. Seeds are sown in seedling pots at a distance of 2 cm from each other and buried 1 cm in the ground.

After this, the seedlings are watered and covered with film or glass. When the first shoots appear in the pots, the film is removed. After this, the seedlings are watered once a week. Also during this period it is necessary to create temperature fluctuations for tomatoes. Move the boxes from one place to another so that the temperature readings change. Do this daily. As soon as the plants have 2 true leaves, the seedlings need to be pricked. Viable, strong plants are planted in separate pots. Two weeks after this, the plants are fed with a nitrophoska solution. Before transplanting tomatoes to a permanent growing location, the crop must be “hardened off”. To begin with, take the flowerpots with young tomatoes outside for an hour, gradually increasing the time spent in the air. As the bush grows, it needs to be pinched. The top must be trimmed so that it produces shoots. The side branches are gradually removed so that they do not take away the vitality of the plant.

After the plant has at least 8 leaves and one true inflorescence, it is transplanted to a permanent place of growth. Small holes up to 12 cm deep are prepared for plants. They are arranged in a checkerboard pattern so that there are no more than 3 plants per 1 square meter. The tomatoes are transplanted into holes together with a lump of earth, dug in, leaving a small depression around the plant, and watered again.

After planting the plants in the ground, they will need care:

plucking a bush;
mulching the soil;
watering at least once a week;
fertilizing with mineral fertilizers 2 times during the flowering period and 2 times during the growing season.

In greenhouses

In greenhouse conditions, tomato bushes with 2 stems are formed. After they reach a height of 1.45 m, the plants are pinched to stop growth. Regular watering of tomatoes in the greenhouse, fertilizing, and tying to a trellis remain mandatory elements of caring for bushes here. Watering both in greenhouse conditions and in open ground is done strictly at the root. If water gets on the leaves, it may cause burns.

Also, Minusinsk tomatoes grown in a greenhouse need to be provided with the correct level of humidity. It should not exceed 70%, especially during the flowering period of plants. For this purpose, be sure to ventilate the greenhouse, especially after watering.

Adviсe

The soil for growing tomatoes must be prepared in advance, preferably in the spring. Tomatoes love organic fertilizers (compost, manure, peat), potassium, phosphorus. If the soil is acidic, then you need to add lime.
When planting in a greenhouse, it is necessary to drill deep holes for each tomato, as for cabbage. This is necessary so that the water falls directly on the root and does not overflow like the river around it.
When planting, the root must be deepened to the first leaf. This will make the root system larger and the plant more resilient.
