Types and varietal diversity of onions
Onion is one of the oldest crops. At first, it was found in the wild, but gradually more and more of its cultivated varieties appeared. Today, onions can be found in almost every summer cottage.
Characteristic
Onion is one of the most ancient herbaceous plants of the Onion subfamily, genus Onion. Found both wild and cultivated. It is a perennial or biennial plant.
Consists of a bulb and a green stem. From the point of view of botany, the bulb is at the same time a kidney, leaves and part of the stem. The stem is also called a pipe, its height can reach about 1 m (depending on the variety). The plant has a characteristic onion, sometimes garlic, aroma, which is associated with a high content of essential oils in the composition.
Onions can be divided into edible and decorative, while some varieties can be attributed to both groups at once. The history of onion cultivation has about 5 thousand years. It is believed that the onion was the first to be cultivated.
Onions are rich in biologically active substances. Among them are sugar, nitrogenous substances, flavonoids, acids of organic origin, phytoncides. The vitamin and mineral composition is represented by vitamins A, B, C, PP, sulfur, phosphorus, calcium. Onion has a pronounced immuno-strengthening, tonic, antibacterial effect. It is useful for the digestive organs, the cardiovascular system, saves from anemia, colds and beriberi.
Main varieties
There are many varieties of onions. It is possible to attribute a plant to one or another group, depending on which feature underlies the classification. The largest and, perhaps, the first is the classification of onions into wild and cultivated. At the same time, wild is also usually edible, but the number of its species is gradually decreasing, which is associated with human economic activity. In this regard, some types of wild onions are listed in the Red Book, and some are considered extinct.
Cultivated onions can also be conditionally divided into edible and decorative (although more often one species combines both characteristics), perennial and biennial.
If we talk about taste, then onions are spicy, semi-sweet and sweet. It is interesting that all species contain sugar, while in bitter species their content is higher than in sweet ones (the former contain about 11% sugars, the latter - 5%). Bitterness is due to the presence of essential oils. The bitter varieties contain the most of them, which also causes the characteristic smell and “tearing” of the onion.
Depending on the time of planting, onions are distinguished, which are planted in spring and winter. Winter onions can be planted from late summer to late September, which should be 25-27 days before the first hard frost. It should take root and get stronger a little before a significant drop in temperatures.
For growing under snow, you need to take frost-resistant varieties. At the same time, this method of growing is suitable only for those regions where snow falls at least 15-20 cm thick in winter. If the snow cover is thinner, then the bulb will die already at a temperature of 10-12 degrees.
Most types of winter onions do not grow turnips well, therefore they are cultivated for the sake of greenery.It usually appears after the snow melts, already in early to mid-April.
One of the most common is onions. It forms an onion resembling a turnip in shape - an elongated circle with a "bottom". It is a biennial plant - in the first season, the crop becomes sevok. These are small onions that are planted for the next season to form onions.
Seeds (chernushka) can be bought or collected in boxes that ripen on an adult plant (you do not need to cut off the onion arrows for this).
"Turnip" is also divided into several varieties - yellow, white and red. Yellow onions are perhaps the most famous variety of the crop. It has a golden husk and white flesh. Due to the large amount of essential oils, yellow turnips emit a strong onion aroma. It is considered a neutral species, since the level of sweetness and bitterness in it is balanced. Differs in universality of application, is suitable for the majority of dishes. In the process of heat treatment, it loses most of the aroma and bitterness, becoming more tender. Due to its high keeping quality and trouble-free transportation, it has become widespread.
White onions have a white husk and have a less harsh and delicate taste. It is he who is the basis of the famous French soup. Among its shortcomings is a short shelf life, only 3-4 months after harvest.
Red onions have purple-burgundy skins and white, purple-veined flesh. It is characterized by a piquant taste, therefore it is often used fresh, it is also called "salad".
It is a mistake to think that red is necessarily a sweet onion. There are both semi-sweet and bitter varieties. The most famous red onion with a sweet taste is Yalta.It grows in a certain territory of the Crimea and is used like apples, its taste is so sweet and juicy.
A variety of "turnip" is considered shallot, which is a multi-nested species. Other names - "kuschevka" or "family". It got its name due to the fact that 3-15 onions ripen in one nest. Outwardly, they are similar to onion, but have a more elongated shape and less weight.
Green feathers have a light waxy coating and a more delicate flavor. Bulbs also have a mild taste and lack of bulbous smell. It is very much appreciated by gourmets for its delicate, but at the same time piquant taste.
However, it is not recommended to fry it - the shallot becomes bitter. In addition, it is distinguished by a “non-capricious” character - it is not afraid of frost, unpretentious in agricultural technology, and is immune to most diseases characteristic of the culture.
The varieties of onions described above are usually grown to produce a crop - bulbs. Although young green shoots are actively eaten. The next species is grown exclusively for greenery, since it does not grow the bulb. We are talking about a bow-batun. This perennial crop (sometimes grown as an annual) is characterized by high productivity (you can harvest 3-4 times per summer) and cold resistance.
Greens appear in early spring and retain their taste until the onset of autumn frosts. The feather is quite large, hollow inside, so this species is also called piped (shoots resemble pipes). Suitable for salads, first and second courses, widely used in Asian cuisine, in dishes that are cooked in a wok pan. Pairs with fish and seafood.
Taste may vary depending on the species.So, Korean and Japanese varieties are characterized by a more delicate and mild taste than Chinese ones. Despite the relatively simple agricultural technology, batun is demanding on soil fertility.
A stone, or Mongolian bow is similar to a batun. It also produces dark green hollow shoots, but their height and wall thickness are smaller, and the taste is more tender, spicier. The Mongolian onion is found both in cultivated form and in the wild.
Another type of onion for greens is chives. Although it can be attributed to ornamental - the plant is so beautiful during flowering. Other names for schnitt are “rezun” (“chisel”), “tribulka”, “skoroda”.
The greens of such onions are low (up to 30 cm), tender, have a bright green color. Feathers are thin, they can be collected several times per season. The flowering period falls on the end of May-beginning of June, the plant begins to bloom from the second year of life. At the end of summer, instead of flowers, seed pods are formed.
One of the advantages of chives is its frost resistance. Tender shoots withstand a slight negative temperature, and adults are not afraid of frosts down to -8 degrees. The plant does not form bulbs, but has branched roots. It is usually bred by seeds, while the seedlings are very weak, they need careful protection from weeds.
Another favorite of gardeners is a two-year-old leek (or "pearl"). It is also resistant to frost, has no difficulties with agricultural technology, and adapts to most climatic conditions. In general, it is similar to onions, but does not form an onion head.
The crop is the stem (false bulb) and bluish-green shoots. The latter are large and wide shoots similar to garlic, the height of which can reach 1 m.Green feathers are tasty only in late spring-early summer, then they become rough. In autumn, a whitish stem is usually kept in order to increase its size (make it longer), the plant is highly spudded.
Leek is characterized by a delicate delicate taste and spicy onion aroma. Good in salads, soups, as a filling for pies. It is harmoniously combined with cheeses, there are even dishes that are leek stuffed with cheese filling.
There is a wild-growing variety of leek - kavar. Cooks and gourmets appreciate it for its more spicy taste and aroma.
Tiered
The tiered bow has a remarkable "appearance". At the beginning of its growing season, it is similar to a batun. However, later bulbs are formed on its arrow - rather large air bulbs. They are formed at different heights (which explains the name "tiered") around the middle of summer, starting from the second year of the plant's life. Since the bulbs are usually formed in two tiers, it is also called a two-tier.
As they mature, they bend more and more to the ground under their own weight. In contact with the soil, they take root - this is how a new green bush is formed. Because of this feature, this species is also called "walking".
The greens of the multi-tiered onion are juicy, with a somewhat bitter taste and a strong onion aroma. Versatile in use, but goes especially well with meat dishes. Reproduction can be carried out both with the help of bulbs and the traditional planting of bulbs in the ground. The species is characterized by unpretentiousness in care, resistance to cold and drought, the presence of immunity to the most common diseases for culture.
branchy
The fragrant (another name for branched) onion grows in the mountains of Central Asia, the southern territories of Altai, Eastern and Western Siberia. It is common in Kyrgyzstan and Mongolia, where it is called "Dzhusai" and put in most national dishes, it is also used in Japanese cuisine (part of the "miso soup"), it is harmonious in tandem with fish dishes.
The plant does not form a bulb suitable for consumption, only green shoots are usually used for food. They have a slight smell and taste of garlic. Outwardly, they also look like a garlic rosette - flat thin shoots of small height. They can be cut several times during the summer, but this can only be done from the second year of the plant's life. Instead of a bulb, a long stem is formed, the diameter of which is 2-3 cm.
The name "fragrant" species acquired due to the delicate and pronounced aroma of inflorescences. In general, branched onions are unpretentious in care, tolerate drought well, but show good yields only with a sufficient level of soil moisture.
slime
Slizun onions are distinguished primarily by a light, but quite pronounced garlic note in taste. Green shoots are used for food. In appearance, they are flat, fleshy, ribbon-like shoots with rounded edges. Slizun, and it is also called drooping and glandular, is not only suitable for consumption, but will also become a decoration for a summer cottage. During flowering, large inflorescences of white or pink color are formed (blooms in the second year after planting).
The species got its name due to the protruding thick juice (resembling mucus) that appears when you cut off a green feather. The drooping onion was nicknamed because its flower stalks tend to the ground, straightening up only during the period of seed ripening.
It has impressive frost resistance - it can withstand temperatures down to -40 degrees. It grows even at zero temperature. Refers to perennial types of onions, shows a yield of up to 5 years. The method of reproduction is vegetation, it is recommended to plant onions in spring or early autumn.
Speaking about the varieties of onions, it should be noted that it also includes garlic, wild garlic (wild onions with garlic taste and aroma), as well as various varieties of wild and ornamental onions.
Popular varieties
Among the popular varieties of onion sets, "Chalcedony" can be distinguished, respected by gardeners for the possibility of growing in open ground (for the southern regions). Suitable for growing bulbs and herbs, it demonstrates a fairly good yield (an average of 4 kg per 1 m2). The ripening period is 95-110 days, it is characterized by resistance to rot and downy mildew. Medium-sized bulbs, weighing about 100 g, with a pleasant mild taste and slight bitterness.
The early Stuttgarter Riesen variety is also popular. This is due to the short ripening period, aversion to bolting, resistance to powdery mildew, rot, good yield. The bulbs are quite large, weighing 250-300 g, the taste is neutral with a strong aroma.
A similar early-maturing variety is Snowball, which, however, has a more delicate taste with a slight spiciness. It is considered a salad variety.
If we talk about varieties with good keeping quality, then Centurion, Orion, Bamberger (demonstrates high resistance to rot), Sturon, previously considered Stuttgarter Riesen, should be distinguished. With the names "Sturon" and "Centurion", the designation "F1" is usually indicated, which means that they belong to heterotic hybrids.
The description of hybrids usually includes information about good yields, unpretentious care, and varieties demonstrate the ability to store for a long time. Such is the onion "Golden Semko F1", which is more profitable to grow seedlings, and in the southern regions or under the film - seeds as an annual.
Another variety suitable for storage all winter is the mid-early Shetana. It is a universal "turnip" with a ripening period of 70-80 days when planting sevkom. The variety is high-yielding, however, these indicators depend on the method of planting (sevok gives bulbs 2 times larger) and climate features. Suitable for winter planting.
Salad varieties are mostly represented by red onions, which have a pleasant sweetish taste and more delicate greens than other types of turnips. In this category, the Dutch varieties "Bombay" and "Brunswick" should be noted. The first refers to mid-season, the second to early varieties. Both types have a delicate semi-sharp taste and show good keeping quality.
Another variety of red lettuce onions is the mid-season Carmen. From planting (can be propagated by seeds or sets) to harvest, an average of 120-130 days pass. Harvest - bulbs with purple-red husks and semi-sharp flesh. The advantage is good maturation and keeping quality.
Variety "Setton" does not apply exclusively to salad, but this yellow onion is grown by many for fresh consumption. This is due to its sweetish taste with a slight spicy spicy note. At the same time, thanks to the dense skin and upper petals, Setton is well stored and remains juicy for a long time.
The elite varieties include the red onion "Red Baron", characterized by an early ripening period (90-95 days), high yield and keeping quality. The average weight of the bulbs is 18-24 g; to obtain a larger crop, it is recommended to breed onion seedlings.
The Yalta sweet salad onion is incredibly popular. Authentic taste can only be obtained by growing a variety in a certain corner of the Crimea, but in general, Yalta onions can be cultivated in the southern regions and central Russia. Taste and sweetness vary by region and care.
Among the varieties of white onions, it should be noted "Albenka" (an early ripe variety, the bulbs of which are distinguished by a piquant combination of sharpness and sweetness), "White Globe" (an early variety, gardeners note its friendly germination, stable yield, disease resistance). A hybrid white onion is "Sterling" with a ripening period of 110-120 days. It has a unique, dissimilar taste. It can be attributed to the sweet varieties.
If you like a larger "turnip", then you should pay attention to the varieties "Globo" (mid-season lettuce, weight - 600-800 g), "Exhibition" (sweet, late-ripening variety with a similar mass of bulbs).
The varieties of shallots with good keeping quality "Atlas" and "Bessonovsky local" also receive positive feedback from gardeners. The first refers to hybrid, early ripening, the bulbs are small with a beautiful bronze husk. "Bessonovsky" is also characterized by early ripening, forms larger golden bulbs.
Among the best varieties of chives, "Medonos" is usually noted. The first greens can be cut 35 days after germination. Feathers have a beautiful shade, have a semi-sharp taste.
Winter hardiness is characterized by mid-season chives "Albion" and "Spring". The first has a fairly sharp taste, the second is medium-sharp. Winter hardiness is also different onions "Olina", which is suitable for planting for the winter. If planted as a biennial in the spring, then the crop is characterized by good keeping quality.
In the middle lane, you can cultivate such varieties of leeks as the late-ripening "Karantansky", the frost-resistant late-ripening "Winter Giant", the biennial "Elephant's Trunk", and the salad "White Lisbon".
Among the batun, the early ripe "April" deserves attention. If a winter onion is needed, then the semi-sharp "Russian Winter" is usually recommended, which can be grown as an annual and as a perennial variety.
When choosing a particular variety of onion, you should focus on the climatic zone where it will be cultivated. Each region differs in the amount of heat and light received, the duration of summer, so the southern varieties do not have time to ripen in the regions of the Urals and Siberia. And those that are intended for distillation in the Far East, for example, cannot stand high temperatures and drought, which is typical for the southern regions, the Volga region.
For Siberia
Given the harsh climate of Siberia, varieties for cultivation here must be chosen as resistant as possible. They must have time to ripen in a short summer and be unpretentious to the quality of the soil, in particular, produce crops on podzolic soils. In addition, characteristics such as disease resistance, high yield and good keeping quality are important for most gardeners.
These criteria are met by Stuttgarter Risen, Shturon, Centurion, Orion.A slightly shorter shelf life is characterized by the "Red Baron", which belongs to the salad, ideal for making marinades. Good for this region are early ripe "Serpentine" and "Firefly" with an early ripening period.
Varieties "Siberia", "Cherny Prince", "Siberian Annual", as well as hybrid varieties of "Daytona" and "Candy" demonstrate consistently good yields.
Due to the short summer, it is better to grow onion sets rather than seeds. On a feather, you can cultivate a plant in a greenhouse. If its equipment allows, then this can be done all year round. It is better to purchase sevok of medium size or small. Large bulbs are more prone to shooting.
Seeds are planted in open ground at the end of May, but it is better to focus not on calendar dates, but on air and soil temperatures. The temperature of the latter should be at least 8-10 degrees.
Growing winter onions in Siberia is possible, but requires certain measures to protect against the first frosts. To do this, the bulbs planted in the first half of October are deepened and mulched, and covered with coniferous paws for the winter. Of course, frost-resistant varieties intended for this should be chosen for winter.
Given the resistance of leek to cold, it can also be grown in Siberia as seedlings in open ground, as well as in a greenhouse.
For the middle lane
This region is considered optimal for growing most varieties and varieties of onions. However, it should be borne in mind that short-term frosts are possible in early spring and late summer, and rather dry periods occur in the middle of summer. In this regard, it is better to choose cold-resistant and drought-resistant varieties. Perennials must be frost-resistant.
For the middle lane, the best varieties of family onions are "Grasshopper", "Mashenka", "Golden". The Ellan variety, bred relatively recently by domestic breeders, deserves attention. It belongs to the frost-resistant early ripening varieties, shows good yields, but does not have a long storage period. It is better to use it as a salad vegetable, especially since Ellan has a pleasantly sweet, slightly spicy taste.
But the Japanese shallot "Senshui Yellow" is characterized not only by early ripening and high taste characteristics, cold resistance and immunity to most diseases, but also by the ability to be stored for a long time (up to 6-7 months).
For the Urals
The Urals is considered a region of risky farming, therefore, for cultivation here, one should choose varieties with a short and medium ripening period, cold-resistant. Gardeners prefer to breed sevkom culture. If seeds are used, then usually the plant enters the open ground in the form of seedlings. In this case, the onion has time to ripen during a short summer and give a good harvest that can be stored all winter.
Due to the short summer, you need to choose early-ripening and mid-ripening varieties of onions. Despite the fact that the conditions in the Urals are milder than in Siberia, it is better to choose "Siberian" varieties for cultivation. They demonstrate better germination and will be able to better adapt to the climate than those intended for breeding in the central regions and the middle lane.
One of the oldest varieties for this region is "Arzamas". Designed for biennial cultivation through sets. The maturation period is average - from 100 to 110 days. Harvest - a dark yellow turnip with snow-white pulp weighing 50-80 g. It is well stored all winter.
In the Urals, the previously mentioned Bessonovsky local is also well grown with a ripening period of 65-80 days and a turnip weight of 35-55 g. Suitable varieties are also Boterus, Siberian Annual, Buran, Red Baron, hybrid "Hercules".
Winter onions in the Urals should be planted from early September to mid-October, choosing suitable varieties. These include "Shakespeare", "Danilovsky", "Radar", as well as the hybrid "Kip Well".
How to choose?
Onions should be selected taking into account the climatic conditions of its growth. It is also necessary to take into account the features of your site - the condition of the soil, the proximity of underground soils, the location of the site and the onion beds.
If the keeping quality of the crop is a priority, then preference should be given to yellow onions and shallots, and if you cultivate it for salads and fresh consumption, then it is better to choose red and white onions. They have a softer and more versatile taste.
If it is not possible to store sets all winter, then it is better to give preference to the technology of cultivating annual onions. For these purposes, small-sized early-ripening varieties are best suited, as well as hybrids with a small nest and a short growing season (Globe, Lugansky, Stuttgarter Riesen).
If we talk about winter varieties, then Shakespeare, Senshui, Radar deserve attention. For planting for the winter, it is better to choose a set of the smallest fraction with a bulb diameter of 8-14 mm.
It should be decided on the purpose of growing onions - whether the crop will be sets or "full" bulbs for eating. In the first case, seeds should be sown, which by the end of the first season will turn into small onions. They are harvested for storage in the winter, and planted in the ground in the spring to collect bulbs in the fall for consumption and storage.In other words, the plant has a 2-year growing season.
Growing onions through nigella, you can get a quality variety and a large harvest. Planting seeds ensures that they will be properly processed (provided, of course, that the gardener has carried out the necessary preparatory measures). This, in turn, provides a higher resistance of the plant to diseases, better germination.
For regions of risky farming, it is recommended to plant nigella at the beginning of spring at home or in a greenhouse, and transfer it to open ground as the soil reaches suitable temperatures. In the southern regions, it is possible to grow onions through nigella as an annual.
Turnip onions can be used to get a green feather. However, this can only be done at the beginning of summer, while the shoots are tender. As the bulb matures, the feathers become rough and bitter. If the task is to get greens all summer, then it is better to choose perennials of schnitt, batun, slime, and allspice.
If you need an unpretentious, frost-tolerant type of onion, then this is a multi-tiered one. It can not be transplanted up to 10 years, which does not affect its yield. Among the popular varieties are "Odessa", "Gribovsky 38".
Another cold-resistant species is the slime. However, it requires fertile soils with a neutral ph. If this is about your site, choose "Leader", "Green", "Charm".
Unpretentiousness is distinguished by fragrant onions, especially its varieties such as Stargazer, Fragrant, Piquant. However, it is not suitable for dry areas (or will have to be watered frequently), as the lack of moisture greatly affects its yield and feather taste.
If you need to get early greens, then a batun onion is suitable.In addition, you can grow seedlings for planting in the spring in the ground or sow winter varieties in the fall. The latter will please with greenery before anyone else. Then the feathers of the onion grown by seedlings will appear. After others (however, about 2 weeks earlier than other species in the open field), a batun will appear.
By the way, fertile soils are also necessary for the latter. He does not tolerate an increase in the acidity of the earth, its waterlogging.
