Quarantined and Quarantine-Released Prunussp. Accessions: The Integration of Quarantined-Germplasm Inventories into the Germplasm Resources Information Network (GRIN)

Abstract

Prunusgenotypes have a quarantine period of approximately 6 to 8 years. The lack of information on what germplasm is currently quarantined has resulted in duplicate orders and difficulties in planning for plant explorations. Elimination of duplication will make all phases of the plant exploration/collection/virus-indexing/distribution system more efficient and effective which means greater availability of new Prunusgermplasm for breeding and development in the United States. This article briefly reviews plant introduction/quarantine concepts and presents an inventory list of all Prunusgenotypes currently quarantined at the Glenn Dale Plant Introduction and Quarantine Station. This inventory will be added to the Germplasm Resources Information Network (GRIN) which is a computer-based information system available to users who have a terminal with remote communications capabilities. As a result, all interested researchers will have access to information on Prunusthat is in the quarantine system or that has been released. This will alter the planning for plant collection trips, will make more effective use of the existing system, will reduce the need for formal and frequent communications among plant introduction/quarantine participants, and will provide for GRIN the skeletal information to which future evaluation and research data can be added.
