Volume 17, 1985

COVER

The retirement of Professor Dr. W. Gottschalk from the
Chair of Genetics in the Faculty of Sciences, University of
Bonn, in 1985 prompts us to recognize his many contributions
to Pisum genetics and cytology published in the PNL and
elsewhere. He has been a member of the Coordinating Commit-
tee since the inception of the PGA in 1969. He is well known
the world over, has acted as a consultant outside his native
Germany, and has participated in several international re-
search programs, e.g. EURATOM, IAEA. A leader in the field
of mutation genetics, he has always stressed the potential of
higher plants as research tools for solving problems, basic
and applied, which cannot easily be accomplished with other
organisms, if at all. His unique collection of pea mutants
and recombinants is well suited to study questions ranging
from biochemistry and developmental biology to ecology and to
breeding. Ever energetic and committed, Dr. Gottschalk has
over the years guided and supported a staff of creative and
productive associates at his Institute. We hope that his
years of dedicated commitment to science will be rewarded by
many more years of pleasant personal activity (at a pace con-
trolled more by him than by others or events). The papers
contributed to this issue of the PNL by coworkers of the
Institute of Genetics are respectfully dedicated to him.
