In the Institute of Soil Science and Plant Cultivation - State Research Institute in Putawy a reliable method for hop cultivars identification has been developed. This method is based on the analysis of microsatellite molecular markers which are characterized with high level of polymorphism. A set of five specific markers was worked out, which enables identification of all common hop cultivars grown in Poland. The method can be used for investigation of varietal origin of different biological materials: fresh leaves, dry cones and pellets. It has been also successfully used in identification of particular cultivars in mixed samples of cones. It was possible to detect 10% of the contaminant, which confirmed a usefulness of this method for control of authenticity and purity of individual hop batches.
