Seed potatoes

The quality of seed potatoes is an important factor in determining the yield and health of the harvested crop. Developed by the United Nations Economic Commission for Europe (UNECE), the UNECE Standard for Seed Potatoes sets common terminology and minimum commercial quality requirements for the certification of high-quality seed intended for marketing internationally. It is a unique international frame of reference, covering all aspects related to seed-potato certification: (a) varietal identity and purity; (b) genealogy and traceability; (c) diseases and pests; (d) external quality; (e) sizing of tubers; and (f) labelling.
