At least once, everyone has purchased smooth, cylindrical, blunt-ended Dordogne carrots in the supermarket. Retail chains purchase orange vegetables of this variety due to the possibility of long-term waste-free storage and excellent presentation: the majority of root crops look selected.
Characteristics of the carrot variety Dordogne F1
Hybrid of the Nantes variety type from the Dutch breeding company Syngenta Seeds. Root vegetables of equal size with a size variation of 2–3 cm are suitable for fresh consumption, long-term storage, and canning. The difference in the weight of marketable fruits does not exceed 40 g.
The period for achieving marketable conditions from sowing to the start of mass harvesting of carrots does not exceed 140 days. Selective harvesting of root crops begins 3 weeks earlier. The number of distorted fruits that have not reached the standard size does not exceed 5%. The upper part of the root crop, protruding 2–4 cm above the soil, does not undergo greening.
Consumer properties of Dordogne F1 carrots:
- The core of the root crop is not expressed, coarsening does not occur;
- Homogeneous internal structure of the fruit;
- High percentage of sugars and carotene;
- Taste qualities are at the Nantes level;
- Overgrowth and cracking of root crops is excluded;
- The variety is not prone to bolting;
Manufacturability of the variety for farmers and peasants
- Smooth friendly shoots;
- Unpretentiousness to soil quality and acidity;
- Indifference of the variety to the vagaries of the weather;
- Dordogne carrots are suitable for mechanized harvesting: the root crops are not subject to mechanical damage;
- Marketability of root crops is not lower than 95%;
- The short-fruited nature simplifies the packaging and packaging of root crops;
- After mechanical washing, root vegetables do not darken and retain a uniform color;
- Early sowing will ensure selective sale of young carrots in mid-July;
- Harvest preservation in vegetable storage for up to 10 months;
- The attractive presentation of the vegetable ensures stable demand when sold in markets and retail chains: root vegetables have no deviations in shape and size.

Agrotechnics of cultivation
Dordogne is a rare variety among vegetable crops, undemanding to the quality of the soil. Seeds germinate and produce a stable harvest on heavy, dense soils. A necessary requirement is deep autumn plowing: in favorable years, root crops reach a length of 30 cm.
Pre-sowing application of fertilizers, fertilizing during the growing season, measures for soil aeration are reflected in an increase in crop yield.On heavy clay soils with insufficient amounts of compost and humus, it is recommended to add rotted sawdust from deciduous trees in the fall.
Seed germination ranges from 95–98%. In a garden bed, where each seed knows its place when sowing according to the guide, this guarantees the required planting density without bald spots and excessive thickening, which leads to deformation and crushing of the fruit.
Preparation of seed material begins in the fall: experienced gardeners recommend long-term pre-sowing hardening of carrot seeds with frost. Treating seeds to destroy pathogenic microflora is not always required. Seed growers put a warning label on the package if comprehensive seed treatment was carried out before packaging.
Dordogne carrots are among the crops that can survive with infrequent watering. A full growing season will be ensured by repeated loosening and mulching of the ridges when the soil dries out, including both compost and freshly cut lawn grass.
To avoid damage to the fruit, harvesting root vegetables in a personal plot can be done without digging, pulling the vegetables out of the ground by the tops. The tops are firmly connected to the root and do not come off.
