James Hutton Institute: New findings could lead to climate-resilient potato varieties in future

Stress-resistant crops can be an important resource to preserve food security in the face of increased temperatures, such as those brought about by the recent UK heatwave. Dr Taylor said: ““Heat tolerant varieties are especially important for Scottish seed exports to growing markets in warm countries. Although most potato varieties are sensitive to heat there is significant variation in response to heat stress between different potato cultivars, and recent research at the Hutton has led to the discovery of genetic variations which can help protect potato crop yields at high temperature.” Recent leaps in the understanding of genomics, genetics and crop science, funded by the Scottish Government’s Strategic Research Fund, have made this type of genetic screening possible.
