Accomplishments
- Fruit production has been quantified for several popular Berberis thunbergii(Japanese barberry) cultivars using plants growing in landscape situations. We have found that significant differences exist between cultivars as far as how much fruit they produce, how well the seeds germinate and how vigorous the seedlings are. This work has been recently published in HortScience. We established a 3X replicated planting of over 40 cultivars of Japanese barberry and are evaluating fruit production, germination and seedling vigor. Fruit numbers range from 2000 fruits per plant to no fruit per plant depending on the cultivar. These findings suggest that it may be possible to identify some barberry genotypes that present a reduced risk of invasion and others that should be banned due to their high invasive potential. The preliminary results from this study are being published in American Nurseryman.
- A 3X replicated planting of Euonymus alatus (burning bush) cultivars has been established and preliminary data has been gathered on fruit production of each cultivar. Large differences in fruit production appear to exist between cultivars, but none have proven to be completely sterile. Data collection will continue for 3 more years and germination and seedling vigor testing will begin this fall.
- Escaped barberry in unmanaged areas are green leaved, so it is commonly believed that popular cultivated barberry forms cannot be responsible for establishment of invasive populations. We have grown seedlings from numerous purple-leaved cultivars and have proven that all purple-leaved forms produce large numbers of green-leaved offspring that are indistinguishable from other green barberry. We have also conducted studies looking at how shade influences expression of purple-leaved phenotype in barberry. We have demonstrated that genetically purple seedlings will appear green at shade levels above 70%, providing further evidence that green feral barberries in the woods could be coming from cultivated purple forms of the species. This work has been published in the Journal of Environmental Horticulture.
- We have established 3X replicated plantings of Physocarpus opulifolius (eastern ninebark) cultivars that have purple and yellow foliage to evaluate them as potential native alternatives to invasive barberry. The planting contains 10 cultivars and we are quantifying foliage color with a Minolta colormeter and evaluating growth characteristics as well as powdery mildew resistance. A similar replicated planting of Aronia genotypes has been established to determine how suitable this native shrub is as a replacement for invasive burning bush. Ongoing evaluations of Aronia (chokeberry) include growth habit, fall foliage color, and fruit size, color and quantity. Nutraceutical characteristics may also be analyzed in the future.
- In working toward the production of sterile triploid barberries and euonymus, we have been attempting to produce tetraploids of important cultivars using tissue culture as well as seeds. We have been successful at producing tetraploids of 3 barberry cultivars as well as green and purple seedlings. We have also produce tetraploids of one cultivar of burning bush as well as seedling material. These plants are being grown to flowering size to be used for crosses with diploids.
- AFLP DNA fingerprinting of barberry is underway to looking at cultivar identification and to determine to what extent purple barberry cultivars have contributed genetics to invasive populations. We have processed samples from 7 invasive populations and 37 cultivars. Analysis of the data is underway and we are also developing a molecular identification key for the cultivars. It appears that some cultivars in the trade may be renames of other cultivars.
- We have begun harvest of a study where seed from purple and green barberry plants has been sown in 5 different natural environments to determine how well purple seedlings establish and grow in comparison to the typical green form. This work is also looking at the effect of leaf litter and vegetation on establishment.
- A mail survey of members of the Connecticut Nursery and Landscape Association was completed that determined industry preference for possible solutions to the sale and use of invasive plants. The nursery industry is supportive of marketing native alternative plants and development of genetically-altered sterile forms of invasive plants, but was strongly opposed to invasive plant taxation and bans of economically important invasive plants. This work is in press in HortTechnology.
Illinois (T. Hymowitz)
Evaluation of 16,266 Glycine accessions for production of the immunodominant human allergen P34 resulted in identification of Null P34 and low P34 expression lines, and the genetic basis was elucidated. The isolation and introgression of soybean lines with low allergen levels will provide the basis for soybean varietal develop programs to develop low allergen lines support human nutritional needs. Indiana (J. Janick) In 2006, Purdue University released "Adagio" arrugula based on Italian germplasm. Adagio was licensed to the Alf Christianson seed company. Work is progressing on selection for late blooming in Diplotaxis tenuifolia, known as wild arugula. Iowa State (C. Brummer)- We coordinated an evaluation of yellow-flowered alfalfa accessions in collaboration with USDA-ARS in Logan, UT; Ag and Agri-Food Canada, St. Foy, Quebec; South Dakota State Univ.; and USDA-ARS, Mandan, ND.
- We are coordinating an evaluation of yellow-flowered alfalfa populations derived from a previous PI evaluation. Approximately 8 locations in the US and Canada are participating.
- We are collaborating with Mike Casler, USDA-ARS in Madison, WI, and Jerry Cherney, Cornell, on an evaluation of native reed canarygrass collections.
- We are evaluating selection nurseries of orchardgrass populations that are derived from plants selected out of a PI evaluation several years ago.
- We made selections from a reed canarygrass nursery that was composed of the best PIs identified from a germplasm screening several years ago, in collaboration with Mike Casler.
- The NCRPIS now maintains 48,314
accessions, 377 of which were acquired during the period 8/1/2005 - 7/31/2006. These included quinoa, wild and cultivated Helianthus, expired plant
variety protected maize inbred lines, chicory, medicinal plants, Daucus and
ornamentals. Seventy four percent of the collections are available.
- Oilseeds Curator Laura Marek acquired 45 accessions of H. pumilus and one each of H. annuus and H. nuttallii ssp nuttallii; these were collected in Colorado and Wyoming in August, 2005 by Dr. Marek, Dr. Seiler, and Dr. Gulya. Three additional H. pumilus accessions from Colorado were collected by two cooperators and donated in August. Seven H. deserticola accessions were collected in Nevada in July 2005 by a cooperating BLM scientist and donated in August. One H. carnosus accession, collected by botanists from the Bok Historic Sanctuary in Florida, was donated in November 2005. The new sunflower accessions include twelve taxa, five of which previously had no accessions available for distribution. An increased interest by the sunflower research community in wild Helianthus germplasm has resulted in the CGC approved goal of acquiring accessions representative of the complete geographic distribution of all 66 Helianthus taxa. : Seven Brassica napus accessions originally received by the NPGS in 1985 and 1986 from Svalof Weibull AB, Sweden came off PVP protection in 2005 and were received from NCGRP. One Brassica napus still under CSR protection was received from the University of Idaho. One accession of Cuphea carthagenensis was collected in North Carolina by Dr. Joe-Ann McCoy during the fall of 2005.
- Medicinal Plants Curator Joe-Ann McCoy, in collaboration with botanists, Dr. Chick Gaddy, Patrick McMillan, and Dr. Richard Porcher, coordinated a trip in September 2005 which resulted in 20 new accessions. This collection trip covered portions of western North Carolina and the coastal plains and Piedmont sections of South Carolina. The main emphasis of the trip was the collection of native Hypericum germplasm; Federally endangered Echinacea laevigata, was also collected.
- About 1,620 accessions were cultivated for regeneration (and 1,290 were harvested) in Ames, IA, Salinas, CA, Oregon, Parlier, CA, Ponce, PR, Kauai, HI, and St. Croix, Virgin Islands to make this germplasm available to the scientific community. Over 1030 of these were grown in cages using insect pollinators.
- Over 1,620 accessions were grown for regeneration. One annual teosinte, the only active accession in NPGS of Zea nicaraguensis was made available.
- The seed viability of 3,991 accessions was tested, or about 8% of the collection.
- Approximately 964 accessions were backed up in at the National Center for Genetic Resource Preservation (NCGRP) in Ft. Collins, CO; 78% of the collection is now backed up.
- Seed storage personnel stored 1,865 accessions and reviewed inventory counts of another 6,049.
- The
NCRPIS' regeneration program was assisted by the following entities:
- Maize - Dupont / Pioneer Hi-Bred in Kauai; ICIA, Ponce, PR; Carlos Hernandez, C&H Farms, Ponce, PR; USDA-ARS, St. Croix, Virgin Islands.
- Daucus - Rob Maxwell, Seminis Seeds, ID; Roger Freeman, Nunhems Inc. (formerly Sunseeds), OR; Phil Simon, USDA-ARS, Madison, WI.
- Spinacia - Larry Gautney, Sakata Seed America, Inc., CA.
- Petroselinum - Phil Simon, USDA-ARS, Madison, WI.
- Helianthus - Maria Jenderek, USDA-ARS, Parlier, CA.
- Distributions:
- 7,272 accessions (12,514 items) were distributed (external to the NCRPIS) to 545 domestic recipients. Of 746 domestic orders, 341 were distributed to recipients in the NC CSREES region, 76 to the NE region, 197 to the S region, and 132 to the W region.
- Internationally, 7,276 accessions (8,948 items) were distributed to 181 recipients (218 orders).
- Combined external domestic and international distributions were made of 12,766 accessions (21,462 items) to 726 recipients.
- Internal to the NCRPIS, 8,339 unique accessions were utilized viability testing, observation, regeneration, phytosanitary testing, and backup.
- Internally, 1,826 accessions were observed and evaluated for various characteristics. Over 28,273 data point observations were loaded to the Germplasm Resource Information Network, or GRIN, database.
- Digital images were captured on 4,050
accessions, and over 1,722 were transferred to GRIN, facilitated by new
automated image capture and loading software. While newly captured images are
transferred soon after capture, a backlog of older images
require transfer.
- The CDs of the Races of Maize Monograph Collection have been completed and will be sent out upon request by Curator Mark Millard. This version includes the Spanish version of the Races of Maize for Mexico, Raza de Maiz en México.
- Curator Joe-Ann McCoy completed development of a database which catalogs cited medicinal uses of plant taxa from a variety of sources and availability from plant genetic resource collections. This database will be publicly available in fall of 2006.
- Maize was evaluated by our plant pathologist, Charlie Block, for Stewarts wilt, gray leaf spot, anthracnose, and other diseases as opportunities allowed. Dupont/Pioneer Hi-Bred Intl. tested a portion of the maize holdings in their ear mold screen trials in CA, and in corn rootworm and Northern Leaf Blight resistance screening trials in IA.
- D. Kovach, Agronomist, collaborated with SharonMcClurg of NCRPIS and Susan Stieve of OPGC to test the utility of x-ray digital imagery in estimating the degree of chalcid infestation in coriander seed. Correlations between results obtained via image analysis and fruit dissection were significant. They also demonstrated that use of liquid nitrogen treatment methods effectively destroy chalcids in coriander seed.
- Preliminary experiments were conducted on breaking seed dormancy in wild Helianthus and Echinacea. Some promising results were seen for
seed using smoke water and GA3. However, these treatments were not promising for wild Helianthus seed. - Vegetable Curator Kathy Reitsma and Pathologist Charlie Block continue to monitor the effectiveness of the cage program in reducing the incidence of and/or delaying the transmission of squash mosaic virus and other insect vectored diseases in the cucurbits.
- A 2-year observation planting of all available Cichorium accessions was direct seeded in the spring of 2006 so that the collection may be characterized and accession taxonomy verified.
- Pathologist Block collaborated with researchers at ISU and the Univ. of GA to develop immuno-magnetic capture (IMS) and RT-PCR identification of Pantoea stewartii and Acidovorax avenae from intact, washed seeds.
- Horticulturist Mark Widrlechner is developing descriptor lists for Calendula, a crop with ornamental, medicinal, and industrial uses, and for Potentilla.
- Coriandrum germplasm evaluation project was conducted by P. Lopez which utilized AFLP-marker systems to study patterns of genetic diversity, and, with T. Isbell, USDA-NCAUR, IL, evaluated fatty-acid composition in its seed oils.
- Curator Brenner released two ornamental amaranth varieties for cut flower use, Pillar Orange and Pillar Red; these varieties do not shed seeds due to a rare trait -- the seed cases lack an abscission zone at the equator, thus remaining closed. Please see http://= www.ag.iastate.edu/centers/cad/amaranth.html.
- The NC-7 Horticultural Trial network evaluated five new accessions of trees and shrubs in 18 environments for adaptation, aesthetic, and growth habit, and made recommendations as to suitability of plants from past trials for landscape use or need for further evaluation. These five accessions were also shared with 11 public gardens. Much of the evaluation work is conducted by SAES personnel, and the evaluation data are used to match landscape plants with appropriate sites, and to inform us about the climatic and edaphic factors that influence woody plant adaptation.
- Horticulturist Mark Widrlechner provided technical oversight for a team charged with developing the new US Plant Zone Hardiness Map.
- Given the serious threat caused by the introduction of Emerald Ash Borer to the North Central Region, additional attention is being given to collection and conservation strategies and regeneration of Fraxinus germplasm.
- Management of tropical maize germplasm in Ames, IA is challenging. As tropically adapted materials are moved north of their area of adaptation, daylength and other seasonal factor differences can result in very tall, spindly plants that are extremely difficult to pollinate, lodge or do not flower until the daylength shortens in September. Maize Curator Millard and the GEM Project Coord., M. Blanco, conducted shading/daylength control field experiments to determine if height and time to flowering can be reduced to manage and regenerate plant germplasm in Ames.
- V.M. Cruz completed research with associated molecular markers with reproductive life forms of annual and biennial Brassica napus.
- V. Cruz determined that pollen flow occurs between regeneration cages of B. napus at a low frequency; resulting progeny fall within AOSCA seed purity standards.
- Tours were conducted for over 300 station visitors in 2005, including students of all ages, researchers, educators, and international agricultural officials. Tours were provided to 30 ISU students enrolled in the Botany 202 classes to educate them on the importance of germplasm collections.
- Outreach activities included field days and classroom presentations in grade school and secondary school science classes by a variety of personnel. The Iowa Honey Producers meeting was held at the Plant Introduction Station in July. Over fifty honey producers were educated on the effectiveness of Russian Honeybees resistance to mites.
- Research results were published in a variety of scholarly and peer-reviewed journals.
- IT Specialist Peter Cyr and Maize Curator Mark Millard released a software application which automates the capture of digital images and loading to the GRIN database to all interested NPGS users; this tool greatly simplifies the processes and saves time.
- P. Cyr developed a prototype Accession Performance Reporting system which enables genetic resource requestors to report on the quality of the materials, research findings and impacts via a web interface.
- P. Cyr developed software applications which enable transfer of data from handheld PCs directly to GRIN, and enable curators to request pollinator insect addition/removal in regeneration cages and the entomology staff to monitor status of needed pollinator services.
Impacts
- Availability of new information about the traits, genetics, morphology and biology of plant genetic resources, coupled with availability of high quality, pest-free plant germplasm of known provenance facilitates the ability of researchers to selectively target and use plant genetic resources to achieve their objectives.</p>
- Use of improved methods to control, diagnose and detect seed-borne pathogens result in improved plant and seed health and enable unrestricted distribution of disease-free seed.</p>
- Use of diverse plant genetic resources provides opportunities for researchers to develop new crop resources, solutions for production issues, and for growers to more reliably produce crops and contribute to improved animal or consumer health, nutrition and well-being, and stability of our agricultural production and economic systems.</p>
