Grown in too dry conditions.
And/or Wrong variety. You don't say which variety but floury ones will do
as you say especially if they have been subject to drought conditions.
Try some waxy ones and/or drought tolerant ones next year.

Kestral (SE), Spey (MC) and Romano (MC) seem Ok for us
.

Yes, I know we're in a very fortunate position with our private water
supply and it's been a godsend this year. Funny this thing with slugs
though, it seems to be almost impossible to make reliable predictions
about what will or won't be damaged by slugs anywhere except for one's own
garden. Desiree has always been one of the least bad ones for slug damage
here. Almost all white maincrop spuds are bad, anything floury is bad.
The only white maincrop we've had much success with is Valor, some of the
whites with red eyes are not too bad, Picasso and Kestrel haven't been too
bad.


We must try Picasso, someone else said it was good.
May I suggest you try Spey (red eyes) which is a MC unlike Kestral which is
a SE. I understand Spey was bred from Kestral and on our allotment it's
proved as good at avoiding the slugs if not better than it's parent (only a
few slugged per row), nice spud too and coped with the heat/drought well.
May be difficult to find though, I had to plant some of our own this year as
we couldn't find any seed, didn't seem to affect the crop thankfully.
