I am trying to find information on vines in a collection in the UK. I
have found info on most of them but can find nothing on: Blauburger,
Heroldsrebe, Madresfield Court, Muscat Bleu, New York Muscat and
Schuler. I am most interested in the parentage and origin. The names
may have slight spelling mistakes as the labels are very faded! Or
they may be synonyms for better known varieties.

I am grateful for any help,

from Oliver Weston.
