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.

The past year has been a very active one for the TGC. After a year of decreasing membership, the enrollment has climbed from 189 as of January 1, 1958 to 198 as of January 1, 1959. It is also encouraging to note the increase of memberships by institutional libraries to the present number of 9. Meetings of TGC members were held at Montreal and Bloomington, minutes for which appear on the following pages. A new gene list, prepared by a special committee for this report, more than doubles the number of known genes since our last list was issued in 1954. It is also heartening to note the increased activity in linkage studies taking place under the present TGC assigments.

Our financial status continues to be reasonably good, although, as pointed out in the minutes, future income is not likely to keep up with anticipated expenses. The year started with a balance of $179.86 and ended with $153.20.

Both meetings served successfully to expose and air important matters concerning the TGC. We wish to thank those members who attended and assisted us with their helpful discussion. On several items of business we have made the following decisions:

1. A study of financial trends of the TGC suggests that a deficit might soon result from the steadily increasing costs. Assessments will be held at the current rate until a financial crisis occurs, at which time they will be raised to an appropriate level.

2. A complete membership directory and lists of stocks will be issued every second or third Tear with lists of corrections and additions in the intervening years.

3. A new gene list has been prepared for this Report, consisting of symbols, names, brief descriptions, references, and sources of seed stocks for all genes described since the previous list was issued in 1954. As a compromise between opinion at the two meetings, the TGC 4 list is reissued, but in abbreviated form. In designating two separate sources for each gene stock we hope to solve in part the problem of extinction of valuable germ plasm. Credit for preparing this list goes to our appointed committee of C. D. Clayberg (Chairman), L. Butler, C. M. Rick, and P. A. Young.

Recognising the merits of such annual meetings we are making preparations for another one to be held in conjunction with AIBS at the Pennsylvania State University in August, 19

It is with great regret that we announce the resigning of Dr. Warren Barham from the Coordinating Committee. Warren felt compelled to take this action because he recently accepted a position in a field not involving tomato work, but he intends to maintain his membership. He is replaced by Dr. A. L. Harrison.

We extend a special vote of thanks to Dr. Hans Stubbe for his magnificent cooperation in TGC affairs. Among his various helpful activities of the past year, he has placed seed stocks of 100 new radiation,induced mutants at the disposal of the TGC for linkage studies.

We gratefully acknowledge the willing help of the following people in preparing this Report. Dora Hunt, assisted by Frank Martin and Ray King, assumed most of the editing responsibilities, assembled the bibliography, and aided in many other ways. Virginia Borelli typed the stencils.

Three hundred copies of this Report have been issued.
