Climate change seedbank stores crops' wild ancestors

An international operation has been launched to save seeds from wild plants which scientists believe could be crucial in protecting crops from the potentially devastating impact of climate change.

The seeds are from the wild ancestors of important crops - and it is hoped their DNA can be used by plant breeders to give farmers new more robust varieties to grow.

The BBC's rural affairs correspondent Jeremy Cooke has visited Italy - one if dozens of countries taking part in the project - to find out how these seeds are being harvested and to follow their journey back to the Millennium Seed Bank at Kew.
