Conference Wide Dehmer, Klaus J [1]. Coloured potatoes and fluorescent SSR markers – managing genetic resources at the Gross Luesewitz Potato Collections. THE management especially of ex situ preserved plant genetic resources (PGR) asks for a high efficiency in optimally maintaining and utilizing the material, as well as the financial resources allocated for this task. Such a management is of particular importance with regard to clonally propagated species like potato (Solanum tuberosum L.). Here, either annual regenerations have to be conducted in the field or in vitro in the laboratory. Alternatively, an in cryo preservation regime can be employed, which however limits the short-term availability of the PGR material. As for all these methods the extent of the maintenance efforts corresponds directly to the number of accessions preserved in a genebank collection, a molecular identification procedure for redundant material, combined with an assessment of the diversity maintained in PGR collections, are of high importance. In this study, a set of microsatellite-specific primer pairs was applied in multiplex assays to 74 coloured landraces or varieties (black, blue, purple, red potatoes; coloured both in skin and/or flesh) of IPK’s Gross Luesewitz cultivated potato collection (GLKKS). The analysis showed that a high percentage of the accessions can be excluded from the GLKKS, while the remaining entries represent unique and distinct genotypes. This supports the decision to initiate similar studies on larger sets of accessions and even on the entire cultivated potato collection of IPK in the future.
