Summary in English
As the government agency responsible for the Canadian Seed Potato Certification Program, the Canadian Food Inspection Agency (CFIA) has been using molecular confirmation of potato varieties for nearly twenty years. Requests for potato genotyping for variety verification purposes may originate due to possible mix-up of plantlets in repositories which may occur during propagation. But mostly, requests originate during seed potato certification inspections where high levels of variations in a crop are suspected to be caused by rogue varieties and which, therefore result in the refusal to certify the crop as seed potatoes. For many requests, morphological characteristics are not sufficient for identification (plantlets and tuber) and molecular identification is then sought for confirmation of variety. Appropriate identification of the potato varieties is crucial to maintain the high level of quality of the Canadian Seed Potato Certification Program which benefits all stakeholders involved.
