UK genetics project looks for lost apple varieties to protect fruit in climate crisis
Heritage orchard at RHS Rosemoor to be sampled this spring as part of search for previously unrecorded ‘survivor’ cultivars
Gardeners are searching for lost apple varieties by sequencing the genetics of trees in ancient orchards, in the hope they hold traits that can help the fruit survive climate breakdown.
Heritage apple trees at the Royal Horticultural Society (RHS) garden Rosemoor will be sampled this spring with the aim of finding species of apple enjoyed by people hundreds of years ago.
It is hoped some varieties that are thriving despite issues with pests and the changing climate will hold genetic traits that can be used to sustain the UK’s commercial orchards.
The University of Bristol and the craft cider maker Sandford Orchards will receive the genotype of apples from rare and important orchards across England and specifically look at “survivor varieties” that have not previously been recorded. Some trees may be the last of their kind, and their unique genetic code could be preserved as a result of the project.
Keith Edwards, an emeritus professor in the University of Bristol’s school of biological sciences, said: “When we first embarked on this project we were overwhelmed by the public interest. The sheer volume of samples we received by post is testament to the importance of apples in the UK’s food landscape. Identifying and conserving lost or rare apple cultivars is not just about safeguarding biodiversity, it can also boost the UK apple industry’s resilience in the face of climate change.”
