Receive good advice about potato propagation, slightly edited for publication:

"Please be careful. Exchange of germplasm between breeders or scientists is always done according to the quarantine rules of EU. For me it is a huge problem to exchange breeding lines with my colleagues at SCRI. A large amount of money is required to perform all tests on quarantine diseases. Specifically the UK takes a unique position within the EU. They are on an isolated island and like rabies they try to avoid import of diseases from the Continent.

If you import, please be aware of doing illegal things. . . . Do not take potatoes grown for consumption, but official seed potatoes with health certificates from the seed producer."
