Latvia

Latvia has a long-established potato growing tradition and potatoes remain an important part of the country’s agricultural and food culture. The crop is well suited to Latvia’s cool, temperate climate, relatively long summer days and generally suitable soils. Potato cultivation is distributed across the country, with production serving fresh consumption, processing and seed purposes. In 2024, potatoes were grown on approximately 6,892 hectares, representing about 0.107% of Latvia’s total land area. Potatoes continue to have a strong place in the Latvian diet, commonly eaten alongside meat and fish as well as in traditional dishes.

Latvian potato production has historically been closely associated with variety selection and breeding adapted to northern European growing conditions. The country has maintained a notable potato genetic resource base, including old cultivars, local landraces and breeding material. Research institutions have worked on traits such as yield, maturity, disease resistance and suitability for different uses. Latvia’s potato genetic resource collection includes Latvian origin accessions maintained both in field collections and in vitro, while modern research has also used molecular genotyping to assess genetic diversity.

The structure of Latvian potato production has changed substantially since the late 20^th century. Cultivated area has declined from roughly 40,000 hectares in the early 1990s to much smaller areas today, while foreign cultivars have become increasingly dominant. At the same time, Latvia continues to maintain breeding expertise and heritage varieties, particularly through the Priekuļi research centre. Current interests include conservation of traditional varieties, production of healthy seed material, organic and low input cultivation and evaluation of potato quality and disease resistance.

Potatoes were introduced into the territory of present-day Latvia during the 17^th century. A historical Latvian source records that Duke Jacob of Courland received a shipment of potatoes from Hamburg in 1673. Initially, potatoes were mainly associated with the nobility and did not immediately become a major crop. During the late 18^th and especially the 19^th century, however, cultivation expanded among farmers and the crop became increasingly important because of its productivity and ability to perform under local conditions.

The 19^th century marked the beginning of systematic potato variety evaluation in Latvia. A major trial at Priekuļi in 1838 compared 119 potato varieties originating from several European countries and the Americas. Scientific breeding developed further in the early 20^th century, with Pēteris Knappe playing an important pioneering role. The Priekuļi potato breeding programme was formally established in 1931, followed by breeding and research activities at institutions including Stende and Carnikava. More than 60 potato varieties have subsequently been developed in Latvia, including historically important cultivars such as Priekuļu Visagrie, Eksports, Laimdota, Agrie Dzeltenie, Vita, Madara and Skaidra.
