In China, a major potato-producing nation, researchers are racing to develop heat-resistant potato varieties as global warming threatens crop yields. A study led by the International Potato Center (CIP) in Beijing indicates that higher temperatures, predicted by the end of the century, could accelerate tuber growth but lead to reduced harvests.In China, a major potato-producing nation, researchers are racing to develop heat-resistant potato varieties as global warming threatens crop yields.
