Interpretive Summary:

Technical Abstract: The Schultz Potato Virus Collection, containing 17 distinct pathogens, some of which occur as strains, are maintained on Aroostook Farm, Presque Isle, Maine, and at Beltsville, Maryland. The collection, initiated in 1916, is maintained in cages to prevent contamination and insure against loss of the original virus. The collection was maintained by E.S. Schultz until his retirement in 1954, R. E. Webb 1954-1960, W.B. Raymer, 1960-1967, and R.W. Goth 1968-date. Since the discovery of Potato virus S, in 1951, some entries are maintained in the cv Saco, which is immune to viruses PVA, PVS, and PVX. Each potato variety or seedling containing a virus culture is grown under 2 separate cages in the field. Four plants are grown in each cage. Since 1989 ELISA and nucleic acid tests for PSTVd have been used to test all plants for PVA, PVM, PVS, PVX, PVY, PLRV, and PSTV. Tubers harvested from these cages are used for replanting and distribution to other investigators. In addition to serving as Type cultures, material from this collection has been used to study physical properties, strain variations, serological properties, virus vector relationships, genetics and the development of disease- resistant cultivars.
