Abstract
Nowadays, there are well known PCR-based techniques to detect polymorphism in plants. Marker technologies which are applied in breeding and varietal characterization can be exchanged across laboratories with standardization to yield reproducible results. This article describes applying of simple sequence repeats (SSR) markers in European laboratories, in which the reproducibility of these popular markers are examined. One of the European Union interests is characterization of grape varieties and preparation of International Vitis catalogue for comparison global varieties as Chardonnay, Sauvignon, Pinot noir with the domestic for each other country. Grape genome contains of many SSR, which are highly polymorphic. This review provides the latest information in SSR research including novels in research, comparison, development and application of microsatellites.
