National and international regulations require the naming of plants for e.g. phytosanitary reasons, market protection and plant conservation. The trade requires the usage of cultivar names to obtain transparency in the market. All important information is linked to the culivar name (e.g. price, colour, acres, pest resistance, usage). So an international cultivar registration system has been developed to gather and register all cultivars. The whole of descriptions and names can be regarded as a the civil registration service. The register discloses information about cultivars.
