Non-Technical Summary
Statement of Issues and Justification
Perform functions stated in title as designated National Plant Germplasm System genebank for potato.
JUSTIFICATION: Potato is the most important vegetable in the US and the 4th most important world crop after rice, wheat and corn. About 1.4 million acres are grown annually in the US for a production of 45.9 billion pounds, worth $2.43 billion in farm receipts (SR=$206 M, WR=$1501 M, NCR=$491 M, NER=$229M)(National Potato Council, Potato Statistical Yearbook, 1995). Potato chips had retail sales of $4.82 billion in 1995 (Snack Food Association, 1996 State-of-the-Industry Report). Potato is an increasingly popular component of the US diet (Appendix). Only wheat flour exceeds potato in per capita consumption. There is a virtually exploding export market for processed forms (Appendix). Thus improvements in the potato crop have a major impact on society and contribute to an agricultural system which is highly competitive in the global economy. NRSP-6 has an important role to play in the continued importance of potato in the US:
1. Genetic improvement in new potato varieties. Currently grown varieties are a relatively small and uniform group within a large and genetically diverse group of exotic potato species. Thus, NRSP-6 is needed to provide the "new blood" for future varieties with higher consumer acceptance qualities, less reliance on chemical inputs, greater resistance to stresses, and improved yields. This will contribute to a safe and secure food system resulting in healthy, well nourished children, youth, and families, greater harmony between agriculture and the environment, without sacrificing enhanced economic opportunities. Genes which confer resistances are a natural, biologically based pest management technology which contributes to a sustainable agriculture system. NRSP-6 stocks can provide value-added genes which may be incorporated through conventional breeding programs or molecular biology. The practical potential of the NRSP-6 genebank in this regard has expanded greatly with the increasing ease of characterizing and moving exotic genes through biotech.
2. Quarantine issues. Scientists who import potato germplasm must wait 1-2 years for the stocks to pass through quarantine. By preserving germplasm of interest at NRSP-6, the time and expense of quarantine testing is not duplicated, and US scientists can quickly obtain the materials needed for their research. Because potatoes can be easily contaminated with systemic and other pathogens, the US breeders and researchers need NRSP-6 to serve as a center for preservation and distribution of "clean" potato germplasm.
3. Preservation of biodiversity. Natural habitats in which potatoes grow are being increasingly disturbed, threatening the in situ genetic diversity. NRSP- 6 is needed to set collection priorities and organize expeditions, preserving unique germplasm before it is lost. NRSP-6 also is needed to coordinate with foreign agencies and the US plant introduction and quarantine offices for acquisition of valuable stocks from other genebanks.
4. Technology transfer. Data related to the identification, characterization and evaluation of samples must be gathered, organized and made available to users if genetic resources are to be efficiently used. NRSP-6 provides this service. The NRSP-6 germplasm resource is the linchpin for a broad, multidisciplinary multifaceted national program for potato genetic evaluation and improvement. Basic germplasm handling and manipulation research is shared through technology transfer to potato researchers worldwide. The NRSP-6 genebank also serves as a model for conservation of biodiversity, and staff regularly do educational outreach to schools and community groups.
