Varieties of radish that are resistant to bolting are distinguished by their unpretentiousness, high productivity, and attractive spring appearance. Hybrids are suitable for continuous sowing from April to October in open ground, greenhouse or greenhouse.
What is the advantage of non-shooting radish varieties
Breeders are constantly working to develop radish varieties without the ability to shoot. It has not yet been possible to completely remove the “flowering gene”. Under unfavorable conditions, the plant grows tops, produces a peduncle, and then the roots do not form.
To date, it has been possible to develop relatively resistant varieties. Such radishes grow well in open areas or in a greenhouse. It does not react to the length of daylight hours, it is suitable for sowing throughout the season: from April to September, without a break in the summer months.
Hybrids are drought and heat resistant, able to grow in dark or, conversely, open areas.
An important advantage of non-shooting varieties is their high yield. The fruits develop well and gain weight, they do not crack, do not stiffen, and are resistant to hollowness.
What is the difference between varieties of radish that are resistant to bolting and ordinary ones?
The main difference between the non-shooting radish is its immunity to the length of daylight hours. Even planted between July and August, with proper care, these varieties do not produce a peduncle.
Due to the lack of shooting culture has the following advantages:
- varieties give a consistently high yield: from 1 sq. m collect 2 – 4 kg;
- root crops grow larger than in ordinary species: their weight reaches 40 – 50 g, diameter – 4 – 6 mm;
- radishes are stored longer, more suitable for transportation, have a good presentation.
In addition, the lack of flowering favorably affects the taste of root crops. The flesh of a non-shooting radish is always juicy, crispy, dense, not prone to woodiness, cracking or sagging.
Varieties of non-shooting radish
Breeders have bred several early, mid-season and late varieties that are relatively resistant to bolting. To choose a suitable hybrid, you should familiarize yourself with the description of the appearance and taste of the varieties, the advantages and disadvantages of each of them.

In appearance and characteristics, this hybrid resembles a daikon.
Features of growing non-shooting radish
Planting and caring for varieties that are resistant to bolting is practically the same as growing ordinary radishes.
Plants are sown early, in April, so the soil should have time to warm up. For planting, choose fertile areas where snow melts first. At low temperatures, non-shooting radishes go into tops, root crops become smaller.
The best predecessors of varieties resistant to bolting are cucumbers, tomatoes, potatoes. Radish develops well in the neighborhood of carrots, legumes, parsley. Do not plant a plant after cruciferous plants (cabbage, broccoli, turnips). They are natural siderates that oversaturate the soil. As a result, the root crop builds up a dense deciduous mass, and the plant’s yield drops.
Before planting seeds, the site is well dug up and loosened. During summer sowing, the furrows are additionally shed with water.
Non-shooting varieties are susceptible to planting density. The optimal distance between the roots is 4 – 5 cm, 8 – 10 cm are left in the aisle. If the planting pattern is violated, the roots will be small, there is a chance of flowering.
In spring, abundant watering 3-4 times a week is enough for seedlings. During fruit growth and in drought, non-shooting varieties are irrigated daily with plenty of water (10 liters per 1 sq. M). After watering, the earth is loosened and mulched with sawdust.
Organic fertilizers are applied in the fall. Spring top dressing promotes the growth of leaves, bolting. If necessary, if the site has not been treated in the fall, complex minerals and nitrogen-containing preparations are added.
In the case of summer sowing, seedlings must be shaded.
When planting radishes in a greenhouse, the composition of the soil should include peat or compost (with turf – in a ratio of 1: 1). In greenhouse conditions, much attention is paid to ventilation, humidity and lighting.
Pests and diseases
Radishes are among the crops resistant to pests and infections. In a short growing season, fungal or viral diseases do not have time to develop, and insect larvae do not have time to move into the adult stage and cause significant damage to the plant.
With improper care, violation of the irrigation regime, general infection of the site on non-shooting radish varieties, the following diseases may appear:
- Powdery mildew. Fungal infection of radish leaves. It spreads in hot, humid weather, with sudden changes in temperature, or in the vicinity of diseased plants. At an early stage, the leaves are covered with a white powdery coating, which then darkens, brown spots appear on the culture. Treatment: spraying radishes with infusion of wood ash, horsetail rhizomes, colloidal sulfur solution, curdled milk or sour milk. Launched powdery mildew is treated with fungicides. Without treatment, the yield of non-shooting varieties is halved.
- Redis mosaic. Viral incurable disease that affects the leaves. When infected, they become covered with yellowish-green or light green spots, thicken, shrink. Radishes stop growing, fruits do not develop. There is no cure for this disease. In order to stop the spread of infection, damaged plants are removed and burned.
- Blackleg. A fungus that infects young shoots of non-shooting radishes. Develops with improper watering. At the same time, the root neck begins to rot, blacken, and become thinner. The plant collapses, turns yellow and dies. For prevention, radish seeds are soaked in a solution of potassium permanganate before planting, the bed is watered with boiling water, young shoots are sprinkled with charcoal.
- Gray rot. The disease develops due to excessive watering. It is diagnosed by a characteristic gray fluffy coating on the fruits and leaves of radishes. To prevent the development of rot, crushed activated carbon, wood ash, and colloidal sulfur are periodically added to the soil.
Radish leaves resistant to bolting are attacked by insect pests:
- Cabbage butterfly caterpillars. During the summer, the insect manages to breed two generations of offspring – in June and September. The larvae quickly eat the leaves, do not allow the radish to grow normally and form roots. To scare off butterflies ready to lay their eggs, non-shooting varieties are sprayed with an infusion of herbs or spices with a strong aroma (wormwood, basil, cinnamon, citrus fruits, rosemary).
- Cabbage fly. The larvae deposited in the soil damage the roots of young shoots and emerging root crops, eat them out from the inside. To scare away the insect, the bed is sprayed with infusion of tobacco or bay leaf.
- Cruciferous bug. These are bright red-black beetles that suck out the juice, damage the leaves and petioles of the radish, depriving it of nutrition. Parasites do not tolerate the smell of tansy, onion peel, pharmacy chamomile.
- Slugs. They reproduce in high humidity. Slug infestation can completely destroy crops of non-shooting radishes. They destroy leaves, petioles, root crops. Removing pests from the site is difficult. To do this, set up traps, collect pests by hand, spray the beds with an infusion of hot pepper or mustard powder.
- Aphid. It settles on the underside of the leaves, which eventually turn yellow and deform. To remove the colony, the tops are washed with a solution of laundry or tar soap, treated with insecticides.
In addition, on radishes that are resistant to bolting, you can find:
- cabbage moth;
- rapeseed beetle;
- cabbage moth;
- cruciferous flea;
- wireworm;
- larvae of the rapeseed sawfly.
Infusions of tobacco, bay leaf, ground hot pepper, mustard powder, potassium permanganate and laundry soap help to cope with the invasion of insects. In extreme cases, insecticides are used to save the crop.
Conclusion
Gardeners for sowing on their personal plots are increasingly choosing varieties of radish that are resistant to bolting. Such hybrids are suitable for any growing method. They are not demanding on the length of daylight hours, soil composition, humidity level. Plants are resistant to diseases and pests. Non-shooting varieties with proper care always give a high quality crop of dense, crisp fruits with excellent taste. They are suitable for long-term storage and transportation.
