Researchers try producing potatoes resistant to climate change

University of Maine researchers are trying to produce potatoes that can better withstand warming temperatures as the climate changes.

Warming temperatures and an extended growing season can lead to quality problems and disease, Gregory Porter, a professor of crop ecology and management, told the Bangor Daily News.

"The predictions for climate change are heavier rainfall events, and potatoes don't tolerate flooding or wet conditions for long without having other quality problems," Porter said. "If we want potatoes to be continued to be produced successfully in Maine, we need to be able to produce varieties that can be resistant to change."

Around the world, research aimed at mitigating crop damage is underway. A NASA study published this month suggests climate change may affect the production of corn and wheat, reducing yields of both, as soon as 2030.

Maine is coming off of a banner potato crop thanks in part to the success of the Caribou russet, which was developed by UMaine researchers. But Porter fears that even that variety isn't as heat tolerant as necessary to resist the future effects of climate change.
