Approximately 350 accessions are currently available as pathogen-free budwood. Additional virus-free accessions will be available for distribution at yearly intervals during this phase. All accessions are maintained in insect-excluding screenhouses and greenhouses as potted trees in five gallon containers, budded or grafted onto appropriate rootstock.
Via a cooperative arrangement, the Repository utilizes the UCR Citrus Variety Collection as a field planting for the purposes of evaluation and as a source of seeds, pollen, etc. This collection contains approximately 900 accessions of citrus and related genera. Over 50 additional cold-sensitive accessions are maintained at the UC South Coast Research and Extension Center in Irvine, California.
The date collection consists of 75 varieties and hybrids of two Phoenix species (P. dactylifera and P. sylvestris). The collection is maintained as two field-grown palms per accession at the USDA-ARS Desert Conservation Station at Brawley, California and at the University of California Coachella Valley Agricultural Research Station at Thermal, California.
