Early ripe radish of the Rondar variety is ready for consumption 25-28 days after germination. A hybrid of Dutch selection from the Syngenta company has been distributed throughout Russia since 2002, the date of inclusion in the State Register. The Rondar variety is sown in spring and autumn.
Description
The Rondar F1 hybrid has a compact, semi-erect, rather low leaf rosette. Anthocyanin color is visible on the petioles. The leaves, rounded at the top, are slightly elongated, short, and muted green in color. Round root crops with smooth, shiny bright red skin grow up to 3 cm in diameter and weigh 15-30 g. With good care, the Rondar variety ripens smoothly and pleases with uniform root crops. The juicy white pulp of the Rondar hybrid does not lose its characteristic density and elasticity for a long time. The taste is pleasant, characteristic, moderately bitter without pungency.
From 1 sq. m of beds, you can collect from 1 to 3 kg of Rondar F1 hybrid. An overgrown root crop elongates in length, becomes ovoid, and voids are created in the center.

High consumer qualities of the Rondar variety | Requirement for light |
Compact plant | Requirement for abundant watering |
Resistance of the Rondar F1 hybrid to flowering, cracking of root crops and yellowing of foliage; cold resistance |

Preparing seeds for sowing
For a good harvest, radish seeds are properly treated before sowing. If the Rondar variety seeds are from the originating company, they are usually processed. They are sown in the soil. Other seeds need to be sorted out and the small ones thrown away.
- Seeds are soaked in water for 8-12 hours and sown;
- Place in a damp cloth and place in a warm place for a day;
- Warm up in water at a temperature of 48-50 OC for 15 minutes. Then they are cooled and treated with growth stimulants according to the instructions, dried and sown.
Features of cultivation
Hybrid Rondar is grown in open areas and in greenhouses. Plants develop well at temperatures up to 20 OC.
In the open ground
For radishes, choose a sunny area or with light shade before or after lunch.
- Before treating the beds, 20 g of superphosphate and potassium sulfate are scattered over the surface, 5 g of urea or the same amount of minerals is dissolved in 10 liters of water and the soil is watered;
- In spring, radishes are sown in April, but no later than May 10. When the heat is above 25 OC the plant shoots;
- For autumn use, sowing is carried out from the end of July;
- 8-10 cm are left between the rows, seeds are placed at intervals of 3-7 cm;
- Planting depth is up to 2 cm on light soils, 1.5 cm on heavy soils.
In the greenhouse
Due to its rapid ripening, the Rondar variety is suitable for growing indoors. Maintain a temperature of at least 18 OC. In winter, they provide little additional light, because the plant needs a short day of light - up to 12 hours.Compliance with the standard up to 1500 lux.
- Acidic soil is leached by adding up to 15 kg of horse manure per 1 square meter. m;
- When digging soil 1 sq. m of soil add 15 g of potassium chloride or 30 g of potassium magnesia and 40 g of superphosphate;
- Rows are made at a distance of 8-10 cm, seeds are placed every 3-5 cm to a depth of 1-2 cm;
- Radishes can be packed with parsley or carrots;
- For greenhouses, the cassette method of growing the Rondar hybrid is justified;
- During development, the hybrid radish variety Rondar is fed and protected from diseases and pests with wood ash (100 g/m2), tobacco dust, use the preparation for root crops “Zdraven-Aqua”.
Problems during cultivation
Possible problems | Causes |
The structure of radish fruit is fibrous, the taste is bitter | Rare, intermittent, and scanty watering, the soil is dry. For 1 sq. m of crops need 10 liters of water daily, or 15 liters when watering twice a day |
The tops develop, the root crop does not form | Thickened plantings; seeds are deeply embedded; late sowing - at the end of May or June; shaded area. Sometimes when cutting the tops, radish roots grow |
Hollow root vegetables | There was an excess of organic matter and manure. Nitrogen stimulates the development of green mass to the detriment of root crops. The situation is corrected by adding 100 g of wood ash per 1 square meter. m or a solution of 20 g of potassium sulfate per 1 liter of water |
Root vegetables are cracking | Uneven watering. Radishes are watered with warm water in the evening through a watering can |
Shooting | Although the Rondar hybrid is resistant to flowering, a gardener can provoke even such a plant by daily weeding or digging. By shooting, radishes protect themselves from interference, prolonging their genus and producing seeds. |
Diseases and pests
Rondar radish is a hybrid plant that is practically not susceptible to diseases, but pests can attack crops.
Diseases/pests | Signs | Control measures and prevention |
In a greenhouse, radishes can be threatened by cruciferous powdery mildew and downy mildew. | Powdery coating on the bottom or top of radish leaves. The plate becomes deformed and turns brown | Fungicides Ditan M, Ridomil Gold are used |
Vascular bacteriosis | On developed leaves, the veins turn black, the leaves turn yellow and crumble | The infection is transmitted by seeds, which must be soaked for 15-20 minutes in hot water |
Gray rot | Brown spots on root vegetables begin to rot | Sick plants are removed. Prevention - fungicides and collection of plant residues |
Cruciferous flea beetles | Leaves with small holes. Gradually the seedlings dry out | The soil is sprinkled with wood ash and tobacco dust after sowing and on young shoots. Dust with ground pepper as well. Spray a bottle of vinegar with a solution of 10 liters of water |
Cabbage fly | The larvae damage radish roots and bore holes | As a preventative measure in the fall, the remaining cabbage leaves are removed from the garden and the soil is deeply plowed. Do not plant radishes after cabbage or next to it |
Conclusion
A high-yielding hybrid will reveal its potential if you purchase seeds from the original company and regularly water the plant. It is better to apply fertilizing to the soil before sowing. Proper crop rotation will prevent the development of diseases.
