The increasing production of greenhouse vegetables around the world requires new technologies that significantly reduce the cost of cultivation by reducing labor costs. One of these innovations is the cultivation of vegetables, and in particular tomatoes, on low-volume substrates. New varieties are being created especially for modern technologies. One of them is called Organza. An application for its registration in the State Register of Breeding Achievements of Russia was submitted by Monsanto Holland BV in 2006. After 2 years, the new product was included in the register and received approval for the III light zone of the Russian Federation. Recommended for cultivation in extended rotation as a low-volume crop, suitable for film and glass greenhouses. The variety is a hybrid and is therefore labeled F1.
Description
The plant is of an indeterminate type, tall and vigorous. The bush is open and well balanced. The type of development is predominantly generative, which increases productivity. The leaves are medium sized, grayish-green in color. Internodes are not long. The inflorescence is simple. Fruit clusters are beautiful, smooth, and can contain more than 7 ovaries. The peduncle of the variety has an articulation.
The tomatoes are attractive in appearance, they are medium-sized - weighing 60 - 70 grams, or 45 - 49 grams according to the State Register, dense, smooth, obovate or plum-shaped with a small drawstring at the top. Unripe tomatoes are light green, without a green spot at the stem. When ripe, they attract the eye with their bright yellow-orange color. The skin is not thick, glossy. The pulp is juicy, tender, and does not drip when cut. The number of seed nests is mainly 2, sometimes 3. There is a high content of sugars and dry substances in the pulp. The taste is good. In 2018, as part of the “Country Seasons” program, a tomato tasting was held, as a result of which the Organza, Cherry Ira and Campari hybrids surpassed many varietal tomatoes in taste. But so that the taste does not disappoint, experts advise letting the tomatoes ripen completely on the bush, and the dessert taste is achieved a week after the fruit turns orange.
Description of the variety
Organza tomatoes are determinate plants. The bush is tall, spreading is medium. The leaves are small, slightly elongated and colored gray-green. Tomatoes are small in size, slightly elongated. During the ripening period they have a light green color. After ripening they become a rich orange color.

The author of the variety is Monsanto Holland BV. The variety was registered in the State Register in 2008.
Characteristics of the variety
- Organza is a typical representative of mid-season hybrids. From the moment of emergence of seedlings to the beginning of fruiting, about 103 - 113 days pass;
- the growing season in industrial greenhouses lasts from February to July;
- The marketable yield is decent - 21.4 kg per 1 square meter, but for the large-fruited Cunero (F1) taken as the standard, this figure is higher - 30.9 kg from the same area. The yield indicators on peat slabs in 2007 in the production conditions of the Moscow region are as follows: ZAO AF "Belaya Dacha" - 21.4 kg per 1 sq. meters, Agricultural complex "Moskovsky" - 16.9 kg per 1 sq. meters. According to one vegetable grower, he managed to get 4.2 kg of tomatoes from one plant;

The purpose is universal. Very suitable for preservation in its entirety. The advantage of the variety is its productivity; from one square meter you can harvest 21 kg of Organza F1 tomatoes. The variety is tolerant to unfavorable weather and most tomato diseases.
Variety Torbay F1
The tomato has pink fruits and excellent taste. It is not inferior in taste to the proven variety Bull's Heart. A variety for open ground and temporary film shelters. The fruits are large, average weight 200.0 g. There is no green spot on the peduncle. The shape is round, with pronounced ribbing, slightly flattened.

Agricultural technology
If you don't have a commercial greenhouse, don't worry. You can grow Organza in a regular film greenhouse. But first you need to sow the seeds for seedlings. The age of seedlings ready for transplantation is about 50 days. After transplantation, the plant must be tied to a trellis. Form a tomato into 2 stems; for this it is recommended to pinch the second leaf. Good results are obtained by grafting onto the Maxifort (F1) rootstock. Agricultural technology is usual for an indeterminate variety in protected soil.
Despite the fact that Organza is recommended as a low-volume crop, it can also be grown in the ground. Good disease resistance will not only eliminate the frequent use of chemicals, but will also make care easier. Productivity will depend on the implementation of agricultural technology. But you won’t be able to collect seeds for further cultivation on your own.
Early Dutch tomatoes
Seeds of early varieties of tomatoes attract all gardeners because thanks to them, they can produce a harvest in an average of 100 days from the moment of friendly shoots appearing. Early varieties selected by Dutch scientists include:
- Bobcat F1

- Crystal F1
- Big Beef F1
Variety Big Beef F1
This variety belongs to the very large-fruited, so-called beef tomatoes or beefsteak varieties of tomatoes. Like all varieties of this group, the fruits are large, weighing at least 200 grams; tomatoes weighing 350 grams are not uncommon. The shape is round, the color of a ripe tomato is red, very bright. Tomatoes have excellent taste and salad purpose. Ripening begins already on the hundredth day after mass germination of seeds.
Important! In order for the fruits to show their varietal characteristics, this variety must be grown in one stem and constantly be planted. The Big Beef F1 variety is grown in open ground on a trellis. The variety is also suitable for greenhouses. The advantage of this variety is its good tolerance to diseases:
- tobacco mosaic
- stem cancer
- fusarium wilt
- nematode
- gray spot
Also, the advantage of the fruit is the increased content of dry matter and the predominance of pulp over the volume of seed nests. If on one square. Do not place more than 2-3 plants per meter, then from one bush you can collect about 5 kg of tomatoes. The disadvantages include the need to install high trellises, more than 2 m.
If the shoots are not fastened to the trellis in time, they may break under the weight of the fruit. Despite the fact that many gardeners strive to grow the earliest varieties, most of the plot area is usually allocated to varieties with an average ripening period.

Best reviews from our readers
Last year I planted these tomatoes for the first time, it’s a miracle! The tomatoes hung in clusters, even and round, as if they were apples and not tomatoes. The tomatoes taste good, they are the first to ripen, they are quite large, the yield is huge - I am tired of picking them. We didn’t get sick with anything, I fertilized it twice a season, that’s all. Generally unpretentious, it seems to me that you could just water them and there would still be a lot of tomatoes. This year I sowed seeds again for seedlings.
Diva is not a variety, but just my find, it helps out every year, especially this year there were up to 72 fruits on some bushes. Since I love to experiment with new varieties, which sometimes do not give any results, this variety always helps out. Yes, tomato is not as sweet as large-fruited varieties, but for pickling and lecho it always goes away for me. But to eat, I have my favorite varieties. I still treat late blight twice a summer so that it grows until October.
Amazing tomatoes
But these doubts disappear when contemplating the beauty, power, grace and taste of new tomato varieties. More than a thousand of them have been tested, but the current successes of world selection are amazing.
Last year's weather conditions were favorable for tomatoes; I was able to test 51 new varieties and 33 hybrids, 18 of them new. At the same time, he received a record harvest of 240 kg.
First, a little about hybrids. Just a few years ago they could not be distinguished from one another, like twin brothers: all round and red. Now, thanks to the efforts of breeders, their shapes have become very diverse: the pepper-shaped F1 Cornabel, the ribbed-flat F1 Rebelion, with a spout, like its literary prototype, F1 Cyrano. What about the colors? Dark chocolate F1 Ashdod, orange plum F1 Organza, yellow portioned F1 Gualdino . I’m not even talking about pink fruits with their sweet taste.
The best yield was shown by: F1 Diamantino (5.8 kg per plant),
F1 Geronimo (5.6 kg), F1 Velasco (5.6 kg), F1 Gualdino (4.6 kg), F1 Attia (4.4 kg), F1 Red Buffalo (4.4 kg), F1 Sir Elian ( 4.3 kg), F1 Organza (4.2 kg).
I would especially like to highlight the leader of last season – the F1 Silhouette hybrid. This year it was planted in one of the worst places in the greenhouse, but despite this, it showed excellent results (5.3 kg), which indicates its highest plasticity.
The largest fruits were noted for the hybrid F1 Orange Barrel, which pleased two giants with more than 1 kg per plant without any shaping.
The collection of new varieties for 2015 is so diverse that it can satisfy the tastes of any esthete and gourmet. Judge for yourself.
Pink tomatoes always have a sweet taste and tender flesh. The large-fruited varieties Pandarosa Henderson with high yield (4.2 kg) and Mister Hart pink were no exception . An elegant plant of the Pink Heart variety is all hung with delicate fruits; 4.2 kg were collected from one bush. The unusual variety Pink Hairy Boar is distinguished by its pubescent fruits. And the incomparable variety Purple Brandy really has such a strange name for a pink tomato, inherited from its parents.
The largest group is represented by black-fruited tomatoes. This is not surprising. Abroad, they have long understood the undoubted health benefits of the pigments included in their composition. And plus a wonderful taste. What else do you need?

Cooper, Black and Blue Ridge, Swart, Black Sweetie. A choice for every taste!
Of the varieties with orange fruits, I would like to mention Russian Orange with heart-shaped fruits and the inimitable variety Zhemchuzhina Janet, which was bred by the famous Brad Gates as a gift to his wife.
We were also pleased with yellow-fruited varieties: the large-fruited variety Martha Logan, the amazingly beautiful variety Prelest Rose with huge (up to 900 g) fruits and the Golden Canary with fancy (with a spout) fruits collected in clusters of up to 30 pieces.
Unusual yellow-orange and red fruits from newcomers to the Russian garden - varieties German Old and E.T. They are large, weighing up to 600–700 g, beautiful, with a delicate taste. Just a miracle!
