On the front cover: Hodgsonia heteroclita Hook. f. & Thomson. In 1853 this member of the Cucurbitaceae
was named after British civil servant Brian Houghton Hodgson who apparently provided lodging to the
botanists Joseph Dalton Hooker and Thomas Thomson as they carried out field work in the Himalayas.
The Cucurbit Genetics Cooperative (CGC) was organized in 1977 to develop and advance the genetics of
economically important cucurbits. Membership to CGC is voluntary and open to individuals who have an
interest in cucurbit genetics and breeding. CGC membership is on a biennial basis.
For more information on CGC and its membership rates, visit our website (http://cuke.hort.ncsu.edu/cgc)
or contact Tim Ng, (301)458-0243, [email protected].
CGC Reports are issued on an annual basis. The Reports include articles submitted by CGC members for the
use of CGC members. None of the information in the annual report may be used in publications
without the consent of the respective authors for a period of five years.
