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.

Membership continues to increase, the number having risen during the year from 217 to 235 as of January 1, 1961. The financial difficulties predicted in 1958 finaly caught up with us in the summer of 1960, when the balance reached such a low point that it scarcely met obligations to continuing members. The rapid shift from 1959 to the unfavorable situation in 1960 is largely explained by the fact that most members pay on a biennial basis and 1960 was the "off" year. With the favorable mandate of the two open meetings in 1958 and the one held in 1960, we have reluctantly increased the assessments to $.75 per year or $2.OO for three years. The latter bargain figure was adopted as a means for facilitating payments. The response to this change has been gratifying; sufficient funds are already on hand to pay for TGC 11. The balance at the end of 1960 stood at $161.38.

A meeting of the membership was held at Stillwater, Oklahoma in conjunction with the AIBS meetings. This meeting, minutes of which appear on the next page, served the intended purpose of providing opportunity for the membership to air policy matters and conduct other useful business. Following our policy of holding these annual open meetings, we have accepted the AIBS invitation to meet with their affiliated societies sessions at Purdue in August, 1961. If you are planninig to be there, we would appreciate your attending the TGC meeting.

The second list of genes, prepared by the gene list committee chairmaned by Carl Clayberg, was published by Journal of Heredity in July, 1960. The committee on varietal pedigrees, headed by Tom Graham has compiled a large installment of their findings, which appears as an appendix to this Report. Recent progress in linkage studies is reported in this issue by Len Butler, chairman of the linkage committee. It is abundantly evident that our committees are taking their responsibilities seriously, and the TGC can be grateful to them for their efforts.

Many faithful workers assisted in the preparation of this Report. We are especially grateful to Virginia Borelli for her very skillful typing of the stancils and to Dora Hunt for her indispensable editing and aid in many other aspects.

Four hundred copies of this Report have been issued.
