Tunceli Garlic is an endemic garlic variety belonging to the species Allium tuncelianum and is native to Tunceli Province in Türkiye. It was officially registered as a geographical indication under Law No. 6769 on Industrial Property on 19 November 2019.
Tunceli Garlic is a rare species that grows naturally in the wild and is classified as Vulnerable (VU). Its most distinctive feature is that it consists of a single clove. Unlike other garlic varieties it is capable of flowering and producing viable seeds. The ability to propagate through seeds is the primary characteristic that distinguishes this species from cultivated garlics, which typically do not flower or produce fertile seeds.
The bulbs have white outer skins and contain 1 to 4 cloves between them. The clove skin is white while the flesh is dirty white. It contains no or very little anthocyanin pigment. Flowering occurs in July–August. The flowers are pale pink, dirty blue or white and have a short bell shape. Each flower cluster consists of 300–500 individual flowers. The plant has a fibrous root system and thrives easily in rocky and stony terrains at elevations between 1000 and 2500 meters.
The average bulb diameter ranges from 2.8 to 3.4 cm and the height from 2.7 to 3.5 cm. The average bulb weight is 10–30 grams, reaching up to 80 grams under optimal conditions. Its Brix value is 37.94%, making Tunceli Garlic sweeter and less pungent than other garlic varieties. Its active compounds (allicin: 0.08 µg, alliin: 0.36 µg) are similar to those found in other garlic types.
The materials used in production are: seeds, scapes and cloves.
Seed-based production is more advantageous than cultivation of common garlic due to this species’ efficient flowering. The seeds are black, wrinkled and triangular, resembling onion seeds. The weight of 1000 seeds is 3–3.4 grams and their diameter is 1–2 mm. Seeds mature by the end of August.
Tunceli Garlic has a fibrous root system. Despite its natural habitat being rocky and stony, its root development is robust, allowing the plant to grow easily. The plant produces 4–8 long, green, flat strap-shaped leaves. The leaves are 1.5–3 cm wide and 30–45 cm long on average. Their cross-section is semi-concave. The leaves are hairless and arranged in a spiral pattern. Planting and transplanting are carried out between September and November. The field is plowed deeply once or twice in autumn and once shallowly. On average, 2 tons of composted animal manure are applied per hectare.
After soil preparation, planting is done manually. In clove planting, spacing is maintained at 10–12 cm between plants and 30 cm between rows. Approximately 200 kg of bulbs are planted per hectare. Yield from clove planting ranges from 650 to 950 kg per hectare. In seed-based production, yield is 50–100 kg per hectare. Harvesting is carried out in August, and the produce is dried for 8–12 days in a shaded, well-ventilated area before being marketed.
