Research Project: ACQUISITION AND EVALUATION OF CITRUS AND CITRUS RELATIVES IN THE CITRUS VARIETY COLLECTION
2012 Annual Report


1a.Objectives (from AD-416):
Maintain high quality of and upgrade citrus variety collection and citrus relative collection.


1b.Approach (from AD-416):
Acquire new potential accessions for the citrus variety collection and citrus relative collection and NCGRCD protected screenhouse collection, evaluate accessions and potential access, update databases appropriately, and maintain collections in good order for efficient utilization. FORMERLY 5310-21000-008-08S (8/08).


3.Progress Report:

This project relates to objectives 1 and 3 of the parent project (identification of priority genetic resources of citrus and characterization of the phenotype of citrus, respectively). NCGRC has completed uploading the 870 images and 562 data sets into the USDA GRIN system database; these images and data were collected in cooperation with this project. Additional information is being worked to upload into GRIN. This will increase the availability of information on citrus relatives that lacked descriptor data in the past and will allow us to clear up any discrepancies in the identifications of taxa. This data will also be used to consolidate the number of trees per taxa.

Facilitated development of web based identification tool to hosts and potential hosts of US Citrus pests and diseases. During FY12 the Citrus Variety Collection (CVC) was a resource for a USDA-APHIS-PPQ-CPHST funded cooperative agreement to develop an illustrated multi-access key using the Lucid platform to citrus cultivars, species and genera which are hosts and potential hosts of citrus pests and diseases in the United States. The CVC was one of the sites used in the U.S.A. to study and photograph these hosts and potential hosts. The purpose of this project was to develop a comprehensive user-friendly web based identification tool for the USDA PPQ, cooperators, and the Citrus industry when conducting pest and disease surveys. Announcement of release of this site by USDA will occur in the near future: http://itp.lucidcentral.org/id/citrus/hosts/index.htm
