FOREWORD

The Tomato Genetics Cooperative is a group of workers who have a common interest in tomato genetics and who are organized informally for the purpose of exchanging information and stocks. Participation is voluntary, and costs of activities are met by assessments to members.

In reviewing the years activities it has become customary to make reference with pride to the upward shift in memberships. Even though this line is overworked, we cannot refrain from pointing out again that enrollment has increased from 198 to 217 as of January 1, 1960. According to this tabulation the list includes 85 members in 29 different foreign countries.

In spite of the pessimistic attitude expressed last year about TGC finances, the balance seems to be holding up fairly well. The year started with a balance of $153.20 and ended with $164.35. Solvency of our finances can be attributed largely to the increasing sale of backnumbers, mostly to institutional members.

A meeting of the membership was held at Penn State in conjunction with the AIBS sessions. Minutes appear on the next page. In view of the policy to subject the TGC to periodic review by the membership and in consideration of the interest expressed at these meetings, we plan to hold a meeting at Stillwater, Oklahoma in August, 1960 under the same auspices. Attendance by as many TGC members as possible will be greatly appreciated.

The gens list issued in TGC 9 together with additional nomenclatorial rules has been revised and submitted for journal publication. For progress in this work we are indebted to Carl Clayberg, chairman of the gene list committee. Progress in the linkage work is evident in the acceleration of new linkages reported in this issue. Credit for the linkage summary on subsequent pages goes to Len Butler, chairman of the linkage committee.

Plans for the issuing of tomato varietal pedigrees in TGC Reports have been reviewed and approved. Thomas O. Graham, who has voluntarily done all the groundwork, will be in charge of this new activity. All cooperation with him will be greatly appreciated.

An innovation in this issue is the last item--the ten-year index. With the volume of research material that appears in the ten reports, it becomes increasingly frustrating to locate articles of special interest. We hope that the index will help to solve this problem and prove to be of general usefulness.

Apologies are presented for the lateness of this report. A shortage of typists--an unavoidable situation--was responsible. We are very highl7 indebted to Virginia Borelli for her very skillful typing of the stencils and to Dora Hunt for her indispensable editing and aid in many other aspects.

Four hundred copies of this Report have been issued.
