Tobacco - Morning Nicholson, Jennifer [1], Lewis, Ramsey [1]. Biodiversity in the U.S. Nicotiana Germplasm Collection. THE U.S. Nicotiana Germplasm Collection was initiated by the USDA in 1934. The collection currently consists of approximately 1244 tobacco introductions, 656 cultivars, 224 accessions representing 59 Nicotiana species, 50 interspecific hybrids, and a newly introduced set of mutants. Although the collection was initially begun as a resource for tobacco breeders, it is also utilized extensively by researchers in plant pathology, plant molecular biology, and biotechnology, including molecular “pharming”. Recent advances in tobacco genomics and molecular marker technologies will enhance the use of this species for genetics research. New efforts to characterize the molecular diversity in the Nicotiana species have been initiated. In one project a large set of highly diverse N. rustica accessions is being characterized for phenotypic and molecular diversity. The worldwide collections of the Sylvestris and Tomentosae sections of the genus are also being screened to determine the diversity in the progenitor species of N. tabacum. The germplasm collection will continue to provide useful tools for researchers in a variety of disciplines.
