Technical Session G and H: Potato Biodiversity and its use in Breeding, Nutrition and Health

Chair: Daniel Caldiz – Director Global Agronomy R&D | McCain Foods

Co-chair: Alfonso del Rio – Senior Scientist | University of Wisconsin

Tuesday 29 May – 12.30 – 14:50 hrs

Summary:

Potato is the world’s 4th most important food crop (after maize, wheat and rice) in terms of production and area cultivated. Reports indicate that the nutritive value of potato per unit of land is 2 or 3 times that of cereals and that it provides more calories, vitamins and nutrients per unit of land than other staple crops. These top four crops supply a greater part of the world’s diet than the next 26 ranked crops combined. Potato biodiversity in the form of cultivated potato varieties and landraces, along with their wild relatives, offer a valuable, unique, and diverse source of genetic variation. This has historically provided various traits which have been used for advances in potato breeding and in basic sciences. In fact, these important sources of genetic variation have played critical roles to create modern varieties with enhanced adaptation to emerging diseases, pests, changing environmental stresses (e.g., due to climate change) and changing consumer preferences and needs (e.g., enhanced nutritional benefi ts).

Therefore, initiatives to foster dialogue and to integrate global eff orts are encouraged to identify what’s next in potato research so that we may be able to outline new strategies for better manage and use potato biodiversity in the face of new challenges.
