Mission:
The mission of the National Germplasm Repository for Citrus and Dates is to collect, maintain, evaluate, preserve, and distribute germplasm of citrus, dates, and related Aurantioideae genera and Phoenix species. The achievement of this goal involves: 1) acquisition of the widest possible genetic diversity within citrus and dates to reduce genetic vulnerability in the future, 2) testing and treatment of accessions for pathogenic organisms, 3) maintenance of accessions in a protected, pest-free environment, 4) genetic, horticultural, and physiological characterization and evaluation of accessions, 5) establishment of an informational record for each accession covering acquisition, inventory, evaluation, and gene descriptor data, 6) distribution of pathogen-free germplasm to qualified researchers throughout the world, and 7) research into improved methods of collection, evaluation, propagation, preservation, and distribution.

NOTICE – JULY 26, 2017

Huanglongbing (HLB, aka citrus greening disease) was confirmed in Riverside County, California in a backyard tree (See attached news release).  As a result, the NCGRCD and the University of California Riverside have been placed in a HLB Quarantine Zone. Presently, THE REPOSITORY CANNOT DISTRIBUTE ANY Rutaceous plant MATERIAL. This action does NOT affect requests for date palm germplasm.

 

The NCGRCD staff are working very closely with County, State, and Federal Regulators to implement a distribution program that will ensure recipients receive only germplasm from the Repository that has been rigorously tested for HLB-associated pathogens (and other citrus pathogens as well). If you are interested in placing a request for Citrus/Rutaceae germplasm, please contact us, but with the understanding that it may be several months before your request will be addressed. Thank you for your patience and understanding.
