The Canadian seed potato certification program is based on a flush through system whereby laboratory tested disease free Nuclear Stock class material provides the basis for successive field generations of seed potatoes. After a maximum of 7 field generations, crops are no longer eligible for sale as seed. Seed potatoes under certification must meet the requirements of the Seeds Regulations Part II Seed Potatoes. Seed potato crop eligibility, in the Canadian certification program is primarily based on regulatory tolerances for visual disease readings and varietal mixtures in the crop, land use history, as well as seed source planted, laboratory testing and supporting documentation.
