USDA ARS CRIS Project CRIS 2072-21000-049-00D - National Clonal Germplasm Repository, Corvallis, Oregon Management of temperate adapted fruit, nut, and specialty crop genetic resources and associated information This genebank directly contributes to the accomplishment of the 2012 – 2017 ARS Strategic Plan GOAL 3: Crop Production and Protection 3.1 Plant Genetic Resources, Genomics, Genetic Improvement, and Crop Production Mission The executive priorities of these management units are 1) FOOD SECURITY, through conservation of plant genetic resources, and 2) GLOBAL CLIMATE CHANGE, through research in plant adaptation to changing environments. This genebank was established to collect, maintain, distribute and evaluate germplasm of an array of temperate, arctic, and subartic specialty crops including: Actinidia, Corylus, Fragaria, Humulus, Mentha, Pyrus, Ribes, Rubus, Vaccinium and other specialty crops. The research program directly supports agriculture and horticulture in the region. The research pursued here adheres closely to the practical problems of germplasm storage and maintenance, including in vitro culture and cryopreservation, virus and disease testing, identity verification, and seed and clonal propagation techniques. We are a genebank for invaluable clonal plant resources. We will preserve this diverse living germplasm for all people for all time. Motto Plant diversity for a diverse future. Guiding Principles Preserve diverse genotypes of assigned genera of fruit, nut, and specialty crops. Distribute plant genetic resources to international and domestic researchers. Operate and act safely with consideration for all employees, collaborators, and the public. Operate and act without discrimination to race, color, religion, sex, national origin, age or disability. Goals The Corvallis genebank staff has identified major goal areas:

• Collection-preservation: To preserve assigned clonal plant collections in good health and identity. • Administration-workplace: To effectively manage resources to operate USDA-ARS facilities. • Information management: To collect, organize, and provide accurate information on plant resources. • Distribution: To provide plant material to researchers worldwide. • Pathology: To identify and eliminate germplasm-borne pathogens. • New acquisitions-collections: To locate, collect, and obtain plants and seed to represent world diversity of

assigned genera. • Research: To improve the preservation of the collection, gather information and collaborate with other

scientists on crop development. • Public Relations: To inform and serve the public.

Objectives 1) The NCGR-Corvallis will conserve global genetic resources for hazelnuts, strawberries, hops, mint, currants, gooseberries, blackberries, raspberries, hybrid berries, blueberries, cranberries, lingonberries, kiwifruit, pawpaws, pears, juneberries, mountain ash, quince, elderberries, and graft- or cross- compatible relatives and other edible fruits. Clones will be preserved by keeping living plants in orchards and field collections, in greenhouses and screenhouses. Seeds and pollen of species relatives will be stored in freezers or coolers. The NCGR staff will work with ARS staff at

1-3

Ft. Collins for cryopreservation of dormant buds of woody plants in the collection. Pathogen testing- and elimination- procedures will be performed on clonal germplasm. Botanical and horticultural identity of genetic resources will be confirmed through phenotypic and genotypic approaches. 2) We will develop new or improved primary and secondary backup preservation procedures for the assigned genetic resources. 3) We will develop genetic marker-based approaches for genetic diversity assessment of the genera in the collections. Clonal fingerprinting techniques will be developed as baselines for clonal horticultural identity recognition. Genetic diversity for other assigned crops will be examined. 4) The NCGR-Corvallis will annually distribute > 5,000 accessions of the genetic resources of specialty crops. Web pages will be developed to transfer information to researchers and the public concerning crop evaluation and unique clonal characters. Order processing and database management will be integrated with the GRIN-Global system. Passport information including pedigree or collection locality, inventory maintenance, and evaluation information will be maintained on the Germplasm Resource Information Network (GRIN) database. Summary The major CRIS is assigned to preserve, collect, distribute, and evaluate genetic resources of about 60 temperate arctic and subarctic climate genera. These genera fall into the general categories of small fruits, tree fruit, nuts, herbaceous perennials, revegetation, and agronomic crops. The economic importance of these crops is increasing internationally. Many countries are entering in competition to produce these crops as transportation and storage survivability becomes easier. Many countries and every state in the US produces berry crops of those assigned to the Corvallis Repository. Strawberries rank in the top 20 most valuable commercial agricultural crops in the country. Pears, hazelnuts (filberts), and hops, while being crops of regional commercial importance, are also of increasing interest throughout the country. These high value specialty crops assigned to the Corvallis genebank offer important and healthy variation to American diets, add unique flavors for food products, and provide ornamental crops to beautify our surroundings. . The fresh and processed value of these crops is significant to domestic markets and international trade. Nursery crop production is also a significant client of genetic resources produced at the genebank. Though wild diversity for these crops is great at present, concern exists as native habitats are encroached on by development, and old selections become unavailable through neglect or loss. Native habitats include locations on six continents from sea level to 3000 meters elevation, and from arctic through sub-tropical and tropical zones. Several of the economically important genera include crops with centers of origin in North America. Several of these genera have cultivars which are three to four hundred years old. The mission, objectives, and actions of the repository are essential to the improvement of cultivars and continued or increased use of these high-value specialty crops. Related practical research is underway concerning taxonomy and cytology of mint, strawberries, blackberries, and raspberries; restriction sites in nuclear and chloroplast genomes of currants and gooseberries; seed germination of raspberries and blackberries; virus detection and elimination in strawberries, hazelnuts, pears, blueberries and cranberries. Viroid and phytoplasma elimination are now added to health certification of plant genetic resources.

Development of efficient methods for germplasm preservation is a high priority throughout the world. Development of a cooperative plan for in situ preservation of cranberries in the Middle Atlantic States is under development with the US Forest Service, State Heritage Botanists, and other ARS cooperators. Alternative storage and back-up technology is needed to safeguard the traditional preservation methods of orchards, fields, screenhouse and greenhouse-grown plants. In vitro techniques when combined with thermotherapy aid in virus elimination. Virus tested in vitro cultured plants provide clean material for plant distribution, satisfying many quarantine regulations. How is the Program Unique? The Corvallis genebank is unique in the world for accumulating the diversity and global representation of wild and cultivated genetic resources of the assigned genera. Specialty and fruit genebanks of other countries have tended to specialize in genotypes and species of regional interests. To summarize the program by genus: Actinidia (hardy kiwifruit): initial representation of cultivated genotypes; beginning representation of world species collections. Some materials from Russia and China. This material is preserved as a secondary backup for the NCGR-Davis primary collection. Corylus (hazelnuts/filberts): representation of world genotypes including those from Spain, Italy, Yugoslavia, Romania, France, and New York and Oregon in the United States. Wild species are represented from the US, China, Korea, Republic of Georgia, Azerbaijan, and Europe. The collection is being screened for Eastern filbert blight resistance genes. Fragaria (strawberries): representation of the hybrid cultivars from breeding programs in about 20 US states and about 20 countries. Recent collecting trips have brought crop wild relatives from Chile, Japan, Vietnam, Canada, the Pacific Northwest, Northern Rocky Mountains and Alaska.. Mentha (mint): Representation of commercial cultivars and of world species. Pyrus (pears): Representation of European cultivars, very good representation of Asian cultivars; the most comprehensive species collection in the world (some gaps and taxonomic questions from Asia); good representation of intergeneric hybrids. Ribes (currants and gooseberries): Representation of cultivated currants and gooseberries; representation of North American species (gaps from South America and Asia). Rheum (Rhubarb): Three species and seventy-five major cultivars are represented. Rubus (blackberries and raspberries): very good representation of raspberry and blackberry cultivars; very good representation of Chinese species, some South American representatives; good representation of world species. Vaccinium (blueberries and cranberries): good representation of blueberry and cranberry cultivars; very good representation of lingonberry cultivars; very good representation of North American species, some examples of South American, Japan, Russian Far East, and European species. Other Specialty Horticultural Genera (Corvallis) Amelanchier (shadbush): fair representation of cultivars and species. Arbutus (manzanita): poor representation of cultivars or species. Asimina triloba (Pawpaw): variety trial planting started 1995 (preserved by the satellite repository at Kentucky State University). Cydonia (quince): good representation of cultivars and species. Escallonia: poor representation of South American shrubby species. Gaultheria (salal): poor representation of species. Gaylussacia (huckleberry): poor representation of species. Holodiscus (ornamental shrub): poor representation of species. Lonicera edulus (edible fruited honeysuckle): wild collections of Asian species Juglans cinerea (butternut): fair representation of cultivars as backup for NCGR-Davis. Mespilus (medlar): fair representation of cultivars. Peraphyllum (shrub): poor representation of species. Pycnanthemum (mint relative): very good representation of species. Sambucus (elderberry): poor representation of cultivars and species. Sorbus (mountain ash): fair representation of species. Permits Quarantine Title 7 - Agriculture CFR 319.37 and its revisions, describe the plant quarantine programs in place for plant

importation. The Repository works with federal quarantine officials to insure that these regulations are followed. We work with USDA-APHIS as closely as possible to coordinate entry of foreign plant materials. The USDA APHIS now has a website where requests for new and renewed permits can be made on-line.

http://www.aphis.usda.gov/plant_health/permits/plantproducts.shtml

We have been granted permits for: • Permit Number PCIP-19-00357 Granted to Dr. Kim Hummer. Plant material under this permit is initially inspected

in Beltsville at Building 580, USDA-APHIS, and resides on the Corvallis Repository property. The plants are annually inspected by state inspectors (under USDA-APHIS auspices) until released.

• Permit for importation of noxious weeds for importation of Rubus fruticosus and Rubus moluccanus. This permit was issued in 1992 and is valid for indeterminate amount of time.

• Permit for conditional release pome fruit is granted to Dr. Barbara Gilmore Humulus: The presence of races of hop powdery mildew on different continents has caused more stringent requirements for hop importation. Oregon State Department of Agriculture has a restriction on the entry of Humulus because of powdery mildew races. Pyrus: is a prohibited genus from every country. The pome fruit are processed through National Plant Germplasm Quarantine in Beltsville, Maryland. NCGR staff has a permit for “conditional release” of this germplasm from Beltsville. Ribes is a prohibited genus from all countries except Canada. Plant material is imported through APHIS at Beltsville, Maryland. Rubus and Vaccinium are restricted genus from foreign countries. An import permit (PCIP) must be obtained from APHIS to import these genera.

FY 2019 facilities repairs Our boiler sprung leaks in summer 2019 and was replaced in November 2019. Electrical circuits throughout the building complex, particularly in the greenhouses and screenhouses, were replaced with fault protection. The potting area was moved from the headhouse to outdoors under a roof. This reduces the particulates that could potentially be airborne in the headhouse. Algae built up in our greenhouses and on the outsides of the headhouse and on the concrete screenhouse walkway. Pressure washing of our facilities was arranged through a local contractor. A temporary growing area, SH-11, remains under construction next to SH-07. This will provide space for Vaccinium which are presently over-running the greenhouses.

1-14

Repairs in FY 2020 and beyond: The NCGR-Corvallis was awarded funding to replace 4 greenhouses and 6 screenhouses. This facilities repair was appropriated by US Congress for FY 2020! NCGR-Corvallis received $13.5 M facilities funding for wholesale repair and replacement of our 6 screenhouses and 4 greenhouses, and the attached headhouse. We are working with ARS administrators and facilities managers to develop the plans and repair/replace these growing structures.

The fiberglass of the screenhouse roofs are beyond their life span as of 2020. The wind has broken off panels of fiberglass. Big gaps occur in the roof eves. The integrity of the roof is compromised so that insects can readily infest the plant collections. SH 7 roof damage. Bricks hold down panels.

Inventory of the collection The inventory and location of the inventory of the accessions are taken annually or when a collection is re-propagated or moved. For re-propagation and replacements of clones, the old plants are retained for a period of time until the new plants are visually examined for identity confirmation for greenhouse/screenhouse collections. Original labels are maintained throughout the accessions time. Then, if any questions arise, labels can be consulted regarding identity and propagation schedules. For seed, re-propagations are placed in separate labeled envelops in the larger aluminum/plastic envelop for the accession. New labels are being planned with QR codes that link to the GRIN database for each accession. This will allow for easier inventory maintenance over time as software is developed.
