Potato Blight League Table
This is my attempt to quantify blight susceptibility in the types I've grown. Remember that no potatoes are immune - they just take a bit longer to be affected.
Top of list (lower numbers) - most affected by blight.
Bottom - least affected.
Scale from 1-9 as used by Alan Romans.

4 Red Duke of York
4 Epicure
4 Mandel
4 Mimi

6 Golden Wonder
9 Sarpo Mira (of the types I've grown, out on its own - astonishing blight resistance)
Note that it's not really fair to compare earlies and maincrop in a list like this. Pink Fir isn't a lot more susceptible to blight than Edzell Blue (an early), but it stays in the ground longer so damage is often worse. The positions will also vary depending on the type of cultivation. I have grouped these based on experiences of growing them in pots in Leicestershire, along with a glance at Alan Romans' excellent "Guide to Seed Potato Varieties", which is available through HDRA. Our figures do not always agree but most are fairly close. Figures will change a little, usually for the worse, with time.
