Use of potato wild relatives in pre-breeding for new genetic variability
Looking ahead the next 50 years, researchers and farmers have significant anxiety about continuing to produce enough food for the world’s growing population under the stressors of climate change. Crop wild relatives (CWR) of potato contain valuable traits that can be transferred to consumer varieties to help ensure reliable yields and high-quality potatoes to help shore up food and nutrition security for vulnerable families. Harvesting the valuable traits of CWR also requires that we preserve these valuable varieties to ensure their future use to strengthen our food systems.
This two-day panel discussion – sponsored by the International Potato Center and the Crop Trust – will explore the value and qualities of CWRs (day 1) and discuss how these varieties can be strategically deployed to support global food systems.
The discussion will be tailored to meet the interests of crop breeders, policymakers and crop science students.

Arione da S. Pereira is a researcher at the Brazilian Agricultural Research Corporation (Embrapa). And he is currently a collaborating professor at the Federal University of Pelotas, a research fellow of the National Council for Scientific and Technological Development, and Director of the Brazilian Potato Association (ABBA). His experience on potato breeding began in 1988 and for the last 18 years he has been leading the Embrapa’s program, being directly involved in the release of several cultivars for fresh market and processing. The focus of the program is cultivar development adapted to subtropical and tropical conditions. Priority traits for improvement are tolerance to heat, resistance to PVY, bacterial wilt and late blight, and quality of processing from storage.
