Pentland Lustre was formerly in our Conservation Potato section. It is a part coloured first early released by the Pentlandfield Breeding Station in 1969. In the late 1970s I became very enthusiastic about growing this eelworm resistant product of a Red Craigs Royal cross. It grew well in the garden and produced lots of good looking white / pink tubers which were much to my taste - unfortunately the market for new first earlies was shrinking and Lustre disappeared. Back now as a heritage type- it makes me feel old.
