| Author: | K.E. Hummer |
| Abstract:
The Rubus collection of the United States National Plant Germplasm System is located at NCGR at Corvallis. Of 779 available Rubus accessions, 566 represent species and 213 are clones or selections. The species accessions include 113 different taxa from around the world. Recent collection trips and germplasm exchanges have included 9 additional Chinese species, 5 Pakistani species, R. glaucus Benth. from Ecuador, and 5 cultivars of R. arcticus sub. x stelarcticus Larsson from Sweden. All plants at the Repository undergo virus testing and virus therapy as needed. The primary collection is stored under screen. Backup collections are grown in field plantings where phenological and morphological evaluations are taken, and stored in vitro at 4°C in dark. Methods for cryogenic storage of Rubus meristems are being developed at the Repository. A library of species descriptions, herbarium specimens, and fruit photographs are maintained for plants in the collection. Cuttings, roots, or in vitro plantlets are available for research purposes. | |
