Tomato variety President (F1)
There are two grades - F1 President and F1 President 2. The two hybrids are often described as one and the same, although this is not true. The emergence of both varieties is the merit of the Dutch company Monsanto, but they distribute the seeds under the American brand Seminis, which was taken over by the Dutch corporation in 2005. Both tomatoes have some similarities in appearance and characteristics.
The president
This hybrid is very popular all over the world, it was also appreciated in Russia. The culture is mainly intended for closed ground - film and glass greenhouses, therefore it is suitable for growing in all regions of the country. This variety is not included in the State Register of Breeding Achievements of the Russian Federation.
Description
The creators describe the plant as a medium-sized, semi-determinant type, up to 75 cm high. Although, according to reviews, a tomato grows more than 2 meters in height in a greenhouse. The foliage is moderate, the leaves are simple, small, dark green, slightly wrinkled. The stems are very powerful, they require a garter to the trellis. In the southern regions, where open field cultivation is possible, the President is grown as a stake crop, that is, with a garter on a support or stakes. The originator recommends to form a plant in 1 - 2 stems. There are few stepsons, which makes care easier. The inflorescence is of an intermediate type. The first fruit cluster is laid over 7 - 9 leaves. Up to 8 ovaries can form in each hand.
The fruits are large, leveled, dense. Weight from 200 to 300 grams. The shape is flat-round. At the stage of technical ripeness, the color is light green, there is a faint green spot near the stalk. At the moment of ripeness, the stain disappears, and the fruit turns into an even bright red color. The pulp is fleshy, moderately dense, sweetish. Originators report taste as excellent, but growers report generally mediocre taste.
Characteristics
- Hybrid President is early maturing, from the moment of emergence to the beginning of ripening, 90 - 100 days pass. According to the description of the originators, the first ripe tomatoes appear 68 - 70 days after transplanting the seedlings to a permanent place;
- The tomato yield is excellent - up to 8 kg of fruits are removed from one bush in the greenhouse, of course, to achieve such results, the cultivation technology must be strictly observed;
- I would especially like to mention the immunity of the variety - the plant is resistant to many diseases. Among them: verticillium wilting, fusarium wilting (races 1, 2), tobacco mosaic virus, gray leaf spot, alternaria stem cancer, nematode;
- the transport capabilities are excellent, the keeping quality of the fruits is also good;
- the use of tomatoes is universal. Used for fresh consumption and canning.
Agrotechnics
The President is recommended to grow through seedlings. Tomato seeds are sown 55 - 60 days before planting in a permanent place. Sowing is usually carried out in early March. In the phase of 2 true leaves, picking is carried out, hardening - 2 weeks before transplantation. Those who have grown this variety note that it is demanding on nutrients. Therefore, during planting, complex mineral fertilizers must be applied to the hole. During the formation of the crop, alternate organic and mineral compositions, for example, Kemiru. Watering is moderate, as needed and only with warm water. The best irrigation method is drip irrigation. There must be sufficient lighting in the greenhouse. Planting density - 4 pieces per 1 square meter.
President 2
This hybrid appeared relatively recently and is considered an improved version of its predecessor. The Monsanto Corporation filed an application for its registration in 2005, after 2 years the variety was entered into the State Register of Plants of the Russian Federation with admission in all regions of Russia. Recommended for open ground in personal subsidiary plots, it can also be grown indoors. Suitable for industrial cultivation.
Description
The plant is indeterminate, vigorous, requiring an obligatory garter on a trellis. Moderate leafiness. The leaves are small, dark green, alternate.The surface of the sheet plate is matte, slightly corrugated. The inflorescence is of an intermediate type. The peduncle is articulated. Originators promise high ovary formation. The first brush is formed under 7 to 8 leaves. Each brush has 5 - 6 ovaries.
Fruits are flat-round, ribbed, dense, large, weighing 340 - 360 grams. An unripe tomato is colored light green, when ripe it acquires an orange-red hue. The pulp is fleshy, juicy, dense - when cutting into a salad, the amount of liquid released is minimal. The number of seed nests is 4. The taste is excellent, according to reviews, fruits that ripen for several days at room temperature have the best taste.
Characteristics
- President 2 also applies to early maturing. From the moment of seed germination to the beginning of ripening, 95 - 100 days pass. The crop appears 75 days after transplanting;
- the yield of the variety is about 5 - 7 kg from one bush. According to the State Register of Plants of the Russian Federation - 4.7 kg;
- tomatoes are not prone to cracking;
- tomato is resistant to tobacco mosaic virus and fusarium wilt;
- the crop tolerates transportation over long distances perfectly;
- the keeping quality of the fruits is excellent - they can be stored for up to 3 weeks;
- the way of eating tomatoes is universal. The fruits are used in their natural form, ideal for summer vegetable salad, any type of canning, processed into juice and pasta.
Agricultural technology of President 2 is no different from its predecessor.
The advantages of both varieties are excellent immunity, high commercial quality of tomatoes and universal use of the crop. The downside is the inability to independently collect seed material for further cultivation and the high price of the sold seeds.
