Abstract:
Ribes petraeum Wulf × R. rubrum L. cv.
Viking originated in As, Norway as 'Rote Hollandische' but
was renamed in the United States.
Glen G. Hahn originally imported this clone in the early 1930's because of its resistance to white pine blister rust, Cronartium ribicola J. C. Fischer.
Hahn renamed the
cultivar for the United States market to prevent confusion with R. rubrum cv.
American Red Dutch,
which was rust susceptible. 'Viking' is a vigorous, good-yielding, cold hardy cultivar with resistance to
North American diseases and pests.
White pine blister rust uredia have not been observed on leaves of
this cultivar under natural field conditions throughout the United States, although susceptibility to rust
has been reported under highly infective laboratory conditions.
