First report of Potato leafroll virus, Potato virus A, Potato virus X and Potato virus Y in potato in Greenland

摘要

Potatoes in Greenland are produced in the southwestern region, mainly along the fjords of the west coast between 60° N and 61.5° N. No production of certified seed potatoes has been established in the country and Greenlandic farmers use either seed tubers imported primarily from Denmark and The Netherlands or home-saved seed tubers. Planting takes place between late May and mid-June. Shortly after planting, the potato field is normally covered with acrylic or plastic sheets to increase temperature during cultivation. The harvest period is mid-August to mid-September.
