Scientists Developing Climate-Resilient Potatoes for North America

Federal scientists in Atlantic Canada are working to create a new type of potato that is more resistant to drought and heat, which are becoming more common due to climate change. The team, led by Bourlaye Fofana, is examining wild potato varieties native to the South American Andes that have shown potential for drought resistance. By incorporating the genetic material from these wild potatoes into commercial varieties, scientists aim to increase genetic diversity and make potatoes more resilient to future climate challenges. Initial evaluations have identified 127 diploid potato clones with promising drought tolerance and late maturity. These clones will undergo further study at a breeding program in Fredericton to assess their size, shape, yield potential, and cooking and processing traits. If successful, the new potato varieties could improve food security and support sustainable agriculture in a changing climate.
