Cucurbit Genetics Cooperative Report 16: vi-ix (Introduction) 1993

Introduction

Comments from the CGC Coordinating Committee

The Call for Papers for the 1994 Report (CGC Report No. 17) will be mailed in August 1993. Papers should be submitted to the respective Coordinating Committee members by 31 December 1993. The report will be published by June 1994. 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)
  • Jack E. Staub (cucumber)
  • J. Brent Loy (Cucurbita spp.)
  • Timothy J. Ng, Chairman

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. Robinson

16th Annual CGC Business Meeting

The 16th Annual Business Meeting of the Cucurbit Genetics Cooperative was held on 21 December 1992 in conjunction with the 1992 Cucurbit Conference in Raleigh, North Carolina. Todd Wehner chaired the meeting in Tim Ng's absence, and 21 members and guests (representing six different countries) were in attendance.

An update of CGC Report and CGC membership statistics was presented. Jack Staub was nominated and elected as CGC Coordinating Committee member for cucumber (Cucumis sativus). Jack replaces Todd Wehner, who had completed his ten year term as a member of the Coordinating Committee.

Two amendments to the CC By-laws were proposed by the CGC Chair: (1) to change the By-laws to allow for more than five members on the CGC Gene List Committee, and (2) to limit guaranteed availability of back issues of the CGC Report to only the most recent five issues. The first proposed amendment reflects both the increasing complexity of maintaining gene lists and the willingness of CGC members to volunteer their services in this activity. The second proposed amendment addresses the physical difficulty of storing and maintaining increasing stocks of back issues, the costs of mechanical reproduction of exhausted back issues, and the plans for storing older reports as digitized images.

There was little discussion of the first issues. However, with the second proposed amendment there was concern expressed that CGC should keep all back issues available until a concerted effort was made to get libraries to pick up the entire set for future reference. As CGC By-laws require that any amendments will be discussed further at the 1993 CGC Business Meeting and mail ballots will be included in the August "Call for Papers for CGC Report No. 17" mailing to the membership.

1992 Cucurbit Conference

The 1992 Cucurbit Conference was held 20-23 September 1992 in Raleigh, North Carolina. Participating organizations included the National Cucumber Conference (NCC), the Pickling Cucumber Improvement Committee (PCIC), the Cucurbit Genetics Cooperative (CGC), the Watermelon Research Group (WRG), the Cucurbit Crop Advisory Committee (CCAC), the National Melon Research Group (NMRG), and the Squash and Pumpkin research Group (SPRG). Tom Monaco coordinated the Cucumber Field Day.

There was an informal decision to have a US Cucurbit Conference in even years alternating with EUCARPIA, beginning in 1994. Many of the commodity groups present at the conference agreed to combine into a single cucurbit organization for coordination of the meetings.

1993 Watermelon Research Group Meeting

The 12th annual meeting of the Watermelon Research Group (WRG) was held in Tulsa, Oklahoma, on 31 January 1993. Attendance was up due to a number of plant pathologists who were attending the watermelon fruit blotch workshop. Glen Price (American Sunmelon) made local arrangements and provided watermelon for all. Gary Elmstrom announced that he would be stepping down as WRG Chair after 12 years of service in this capacity, and Ray Martyn (Texas A&M) will be assuming these duties.

US Cucurbit Crop Advisory Committee 1992-1993 Update

On 23 September 1992, the US Cucurbit Crop Advisory Committee (CCAC) met in Raleigh, North Carolina in conjunction with the Cucurbit Conference organized by the Department of Horticultural Science, North Carolina State University.

The Core Concept and its applicability to cucurbits was further discussed and it was decided to construct core collections for each species based on geographic origin and proven value for one or more specific characters.

The National Seed Storage Laboratory (NSSL) is now accepting samples for long-term storage. NSSL has specific requirements for numbers of seeds and germination percentage that must be met. There were discussions on various aspects of deleting duplicates of accessions; ensuring entry of valuable breeding lines and varieties from scientists either prior to or upon retirement when their program will not be continued; obtaining correct species identification for USDA taxonomists in a timely manner, conditioning acceptance of HortScience Cultivar and Germplasm Release manuscripts upon submission of samples to the National Plant Germplasm System (NPGS); germplasm exchange with Russia, The Netherlands and India; availability of accessions in NPGS; and increase of accessions outside of the US on a contract basis. The CAC Report is approximately four years old and needs to be updated for various reasons including the transfer of the melon collection from Georgia to Iowa, retirements, and progress in evaluating germplasm collections.

Two germplasm evaluation proposals were recommended for funding in FY 1993; Evaluation of the U.S. plant introduction collection of melon (Cucumis melo) and squash (Cucurbita moschata and C. pepo) for resistance to gummy stem blight (Didymella bryoniae Auersw.) Rehm (M.A. Kyle and T.A. Zitter), and Genetic diversity in cucumber (Cucumis sativus L.) and melon (Cucumis melo L.) accessions as measured by morphological and biochemical genetic markers (J.E. Staub and J.D. McCreight).

The 1993 meeting is scheduled for July 24 in Nashville, Tennessee, in conjunction with the Annual Meeting of the American Society for Horticultural Science.
