Accomplishments
PROGRESS AND PRINCIPAL ACCOMPLISHMENTS
A. Introduction of New Stocks
Dr. Bamberg and Charles Fernandez (US Potato Genebank) had a successful expedition to the southwest United States and obtained four new accessions of Solanum jamesii. They explored the Northwest corner of Arizona and found the first potato germplasm from Mojave County, two new collections at previous herbarium record sites near Flagstaff, and a new site on the south rim of the Grand Canyon.
A total of 13 accessions were assigned PI numbers in 2003: two from Sweden, one from Poland, one from Mexico, five from the United Kingdom, and four from the SW United States. These accessions are now available from the NRSP-6 Solanum germplasm collection.
Several steps were taken in the past year to promote and educate researchers of NRSP-6?s services and stocks. The NRSP-6 web page (http://www.ars-grin.gov/nr6) has been updated and made more user friendly. Clientele that have ordered from NRSP-6 in the past four years are contacted biannually informing them of new materials that are now available either as true seed, tubers, in vitro plantlets, or herbarium samples. An NRSP-6 informational poster was presented at the PAA and CSSA meetings. A new trifold pamphlet was printed for distribution to school and tour groups and is available on the web page.
B. Preservation and Increase of Stocks
In 2003, a total of 124 accessions were increased as botanical seed populations. A total of 900 potato spindle tuber viroid (PSTV) tests were performed on seed increase parents, seedlots and research materials. Germination tests were performed on 1,437 accessions, ploidy determinations were made on 51 accessions, and tetrazolium seed viability tests were done on 101 seedlots.
Tetrazolium testing is a new tool to help increase understanding of poor germination on some seedlots. Investigations continue on low germ seedlots, trying different heat treatments and longer GA presoak. A project with NSSL on long-term potato seed viability in different storage systems and methods of prestorage handling was started.
The Association of Potato Intergenebank Collaborators (APIC) (visit the APIC database at www.potgenebank.org/ipd/) have several cooperative research projects planned: a graduate student working on an in-situ pollen study at CIP (The International Potato Center), a recessive allele mining study for nematode resistance in S. andigena with Russian (VIR) colleagues, and a completed publication of the screening S. andigena for new sources of nematode resistance in collaboration with Dr. S. Kiru (VIR). Dr. A. Del Rio attended the APIC meeting in Valdivia, Chile in March 2004.
Publications of collections and documentation of stocks play an important role in information dissemination. 2003 had two publications of significant importance to the Genebank: Wild Potatoes (Solanum section Petota) of North and Central America, Spooner et al. and A decade of collecting and research on wild potatoes of the Southwest USA, Bamberg et al.
Work continued with Dr. C. Miller?s lab screening for antioxidants in uncolored wild potato species tubers. Previous screening among species identified ones with promising levels of tuber antioxidant capacity. Some diploid ?Mexican? species seem to have high antioxidants in common: S. cardiophyllum, S. jamesii, and S. pinnatisectum. Continued fine screening is discovering high levels of antioxidants in species that are crossable to tuberosum and known to have acceptable levels of glycoalkaloids.
Screening the minicore collection for the ability to stop or reduce the growth of tumors of Agrobacterium tumefaciens. From a literature search on anti-cancer foods there is evidence that some potato varieties have high levels of proteinase inhibitors known to help in the fight against some forms of cancer.
Cold resistant breeding work continues with recurrent selection of S. tuberosum, S. acaule and S. commersonii hybrids. S. commersonii cytoplasm was eliminated as a source of frost resistance in cytoplasmic substitution backcross families. Materials are now maturing earlier with the introgression of very early varieties and which survive in vitro leaf freezing to ?5oC. These samples were tested in the Biotron at Madison using the relative freezing tolerance (RFT) method. The results closely correlate the in vitro leaf-freezing assay.
Screening the S. andigena population (170 accessions) for Jelly End with cooperator Dr. Asunta Tompson at North Dakota. Twelve plants per accession were planted in the screenhouse for tuber production, and a parallel planting was done in ND. The screenhouse tubers are planted in Weslaco, TX and will be evaluated in June.
High glycoalkaloid levels in the leaves correlates to insect resistance and low levels in the tubers makes them palatable. Continued screening and recurrent selection within accessions for high foliage and low tuber glycoalkaloid levels and generated another cycle of tissue for testing in 2004.
A publication entitled ?The Association of Ecogeographic Parameters and Genetic Diversity in S. verrucosum? was completed. Geographical parameters and proximity to related species predict genetic variation in the inbred potato species Solanum verrucosum. Such links had not been previously detected in S. fendleri, S. jamesii or S. sucrense. Resolution and fine-tuning to locations may be enhanced by inbreeding and uniformity. The highest correlations to genetic rarity (a population?s average genetic difference from all others) were latitude, longitude and proximity to the nearest S. hjertingii population.
It is habit to select the largest seedlings when transplanting. Does this practice unknowingly cause genetic drift? A comparison of the genetics of small and large seedlings from original seedlots to detect potential selection in the genebank at transplanting was initiated.
Several interesting mutants were discovered in the collection this past year that are now being crossed for genetic studies. S. fendleri, typically a purple flowered plant with purple highlights, was found pigmentless. A S. microdontum mutant has a fused sepal. Lucky (S. juzepczukii), a Bolivian variety, had a spontaneous clonal dwarf.
C. Classification
Dr. Spooner et al. have published Wild Potatoes (Solanum section Petota) of North and Central America. Dr. Spooner continues to resolve problems in taxonomic classification that impede both efficient documentation and use of the germplasm. At present he is working on a use-based classification of varieties.
D. Distribution
NRSP-6 distributed 8,700 units of seed, 63 tuber families, 943 in vitro stocks, and 153 herbarium samples to clientele in 24 states of the United States and 13 other countries. Internally, NRSP-6 used 2,833 units of seed for chromosome counts, germination tests, identification and taxonomic check plantings, in vitro maintenance, seed increases, PSTV tests, and miscellaneous plantings. The volume and types of stocks sent to various consignee categories are summarized in the table below.

Impacts
- Evaluation experiments will be continued on Solanum species for the following traits: antioxidants, frost hardiness, rooting vigor, tuber calcium, late blight resistance, hormone mutants, proteinase inhibitors, and glycoalkaloids.
- Continuing high quality service with respect to introduction, preservation, classification, evaluation, and distribution of potato germplasm to clients in the U.S. and around the world will pursue the general objective of NRSP-6, to promote and facilitate potato research and breeding.
- APIC Intergenebank projects researching the status and dynamics of genetic diversity in the collection using RAPDs and strengthening ties with sister genebanks around the world will be continued.
