PNL Volume 17 1985

PREFACE

Membership

The Pisum Genetics Association (PGA) is a non-profit,

unincorporated organization established to facilitate the

exchange of information and to ensure the preservation of

valuable genetic stocks. The number of PGA members now

stands at 218-

Membership in the PGA is open to all interested per-

sons. Dues are $10.00 for two years (U.S. currency) and are

used to help defray the costs of publishing the PNL. Mem-

bers are encouraged to pay dues for two or more years to

simplify bookkeeping. Please make prime banker's check or

money orders payable to PISUM GENETICS ASSOCIATION and send

to G. A. Marx, Department of Horticultural Sciences, New

York State Agricultural Experiment Station, Geneva, NY

14456, U.S.A. The PNL will be sent upon receipt of dues.

Response to the letter from the editor which appeared

last year (Volume 16) has been gratifyingly positive.

Individual members have willingly accepted the increase in

dues and have graciously consented to pay their dues for

two years or more in advance. A few have even contributed

something extra, a gesture that gives us a warm glow of

reassurance. I interpret this overall reaction to mean that

members feel that the PNL has value, serves a need, and

should endure.

Although members' dues are essential, contributions of

an extraordinary kind are also vital if the PGA is to sur-

vive. I am delighted to report that the Del Monte Corpora-

tion has made such an extraordinary, PGA-saving, contribu-

tion in the amount of $1,000. Our hearty thanks to Del

Monte for this special gift and for its generous support in

the past.

One need only scan the articles published in the PNL

over the years since the initial issue in 1959 to see that

the nature and content of the articles has undergone a

transformation or evolution of sorts. The advent in recent

years of electrophoresis and other powerful analytical

techniques has allowed researchers to probe ever more

deeply into life's processes and the results of these

investigations have appeared on the pages of the PNL. This

is a favorable trend but for your editor, who is none too

bright in the first place, it poses a particular challenge.

There is an inverse relationship between his ability to

render a fair and critical review and the incidence of

articles dealing with esoteric subjects or techniques. It

is for that reason I gratefully acknowledge the editorial

assistance of the following colleagues: Drs. K. Mudge,

N. D. Polans, S. Shannon, and N. F. Weeden.

PREFACE

The lady affectionately known as our "Clerk", having

retired and no longer a Cornell employee, remains as a

faithful ally. Mrs. Van Kirk has purchased a microcomputer

and a printer and single handedly has prepared all the copy

for PNL Volume 17. Moreover, she continues to perform all

the bookkeeping and most of the organizational tasks

associated with keeping our enterprise afloat. To her goes

the credit for getting the PNL into your hands at a

reasonable time. We tip our collective hats for a job well

done.

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.
