Apropos links, these were the same than already posted in my first post (the part in text size 1). I thought volks might have overlooked them easily
Your're right, the 'Ermakovskaya Mestnaya' should still be around, but the low numbered USO/US varieties... I didn't wanted to say they're extinct, even the old 'Bernburger Einhäusige' is still maintained but these varieties are usually kept only for preservation purposes, maybe also for experimental breeding, and not accessible to private persons. Recently, I contacted the responsible at the VIR by mail using my university account, title and all regarding that subject but haven't got any reply ;( .
BTW, just read your signature... Do you know by any chance whether Bócsa's 'Panorama' variety is still around?
