Research underway to discover causes of senescent sweetening in potato storage

Body

"We aim to provide predictive markers of sweetening onset, and identify candidate genes and markers to accelerate the development of sweetening-resistant varieties"

Researchers at the James Hutton Institute and partner organisations are working to understand the mechanisms behind senescent sweetening, a problem responsible for considerable losses of potato crops during storage, particularly in the processing market.

Speaking at the Scottish Society for Crop Research (SSCR) Potato Winter Meeting 2019, Dr Rob Hancock, based within the Institute’s Cell and Molecular Sciences group, said: “This AHDB-funded project aims to define the biochemical pathways associated with senescent sweetening.
