Papers should be submitted to the respective Coordinating Committee members by 31 December 1992. The report will be published by June 1993. As always, we are eager to hear from CGC members regarding our current activities and the future direction of CGC. Gary W. Elmstrom (melon) Dennis T. Ray (watermelon) Mark G. Hutton (other genera) Todd C. Wehner (cucumber) J. Brent Loy (Cucurbita spp.) Timothy J. Ng, Chair Comments from CGC Gene List Committee Lists of known genes for the Cucurbitaceae have been published previously in Hortscience and in reports of the Cucurbit Genetics Cooperative. CGC is currently publishing complete lists of known genes for cucumber (Cucumis sativus), melon (Cucumis melo), watermelon (Citrullus lanatus), and Cucurbita spp. on a rotating basis. It is hoped that scientists will consult these lists as well as the rules of gene nomenclature for the Cucurbitaceae before choosing a gene name and symbol. Thus, inadvertent duplication of gene names and symbols will be prevented. The rules of gene nomenclature were adopted in order to provide guidelines for the naming and symbolizing of genes previously reported and those which will be reported in the future. Scientists are urged to contact members of the Gene List Committee regarding questions in interpreting the nomenclature rules and in naming and symbolizing new genes. Cucumber: Todd C. Wehner Melon: Michael Pitrat Watermelon: Warren R. Henderson Cucurbita spp.: Mark G. Hutton and Richard W. Robinson Other Genera: Richard W. Robinson Comments from the CGC Gene Curators CGC has appointed Curators for the four major cultivated groups: cucumber, melon, watermelon and Cucurbita spp. A back- up Curator for the "Other genera" category in needed; any one wishing to take on this responsibility should contact the Chair. Curators are responsible for collecting, maintaining and distributing upon request stocks of the known marker genes. CGC members are requested to forward samples of currently held gene stocks to the respective Curator. Cucumber: Todd C. Wehner and Jack E. Staub Melon: J.D. McCreight and Michel Pitrat Other genera: Richard W. Robinson Watermelon: Gary W. Elmstrom, E. Glen Price and Billy B. Rhodes Cucurbita spp.: Mark G. Hutton and Richard W.
