Research Project: Ornamental Plant Germplasm Center

Location: Application Technology Research Unit

Project Number: 3607-21000-015-14
Project Type: Specific Cooperative Agreement

Start Date: May 13, 2008
End Date: May 12, 2013

Objective:
The objectives of this cooperative project are to conserve, distribute, and characterize ornamental plant germplasm, and incorporate new or existing technologies for conserving primarily seed and secondarily clonally propagated germplasm for effective utilization in ornamental horticulture.

Approach:
The Ornamental Plant Germplasm Center was established in 1999 and since then, it has become a fully operational repository for herbaceous ornamental plants and an integral part of the U.S. National Plant Germplasm System. The core mission of the OPGC is “to furnish genetic raw materials and associated information to enhance American floricultural productivity to ensure a high-quality supply of herbaceous ornamentals.” To accomplish this mission, priority genera have been identified to most effectively accomplish its mission including Begonia, Coreopsis, Lilium, Phlox, Rudbeckia, and Viola. Three components inherent within the core OPGC mission include; conservation of genetic resources, characterization of those resources, and education and outreach including distribution of OPGC germplasm to appropriate users. Conservation -- The priority genera collection will continue and include representatives of selected priority species within the genera. Priority species will be identified in collaboration with stakeholders including seed companies, commercial nurseries, and genera-specific technical working groups. Species will be collected primarily through donations and collection trips. Characterization -- Collected material must be adequately characterized to ensure that the germplasm captures genera diversity and that the germplasm is used correctly. Characterization will include genetic “fingerprinting” or mapping as well as phenotypic descriptions based on approved descriptor lists. This information will be entered into the Germplasm Resources Information Network (GRIN) database to increase the accessibility and value of the collection to the industry. Education and Outreach -- Distribution of germplasm to bona fide users will continue to fulfill a need for the industry and establish OPGC as a leading herbaceous ornamental plant repository. By hosting workshops and distributing newsletters, OPGC can educate the industry regarding technologies created, used, and refined through its efforts. OPGC will also maintain its linkage to the industry and professional organizations through participation and memberships in appropriate scientific societies and working groups.
