German Fruit Genebank – looking back 10 years after launching a national network for sustainable preservation of fruit genetic resources

Abstract

In Germany, all activities of long-term preservation, utilization, research and development of fruit genetic resources are based on the German National Program for Genetic Resources of Agricultural and Horticultural Plants. The preservation of fruit genetic resources is the basis for ensuring a sustainable fruit production in Germany. It has a long-lasting tradition, which reaches back to the early decades of the 20th century. Ever since, a multitude of cultivars of different fruit crop species is preserved in public and private germplasm collections. The German Fruit Genebank has been established as a decentralized network 10 years ago aiming at the coordination of the different germplasm collections in Germany to minimize the risk of losing fruit genetic resources. The German Fruit Genebank is organized in species-specific networks. Currently, six of those networks consisting of 41 different collections are held at federal and state governmental institutions as well as in communities and towns, non-governmental organizations, and by private individuals. Because of high priority, the first projects characterizing the genetic resources on trueness-to-type based on pomological and molecular characters were completed in the last few years. About 75% of the apple cultivars belonging to German Fruit Genebank and ~60% of the cherry cultivars could be determined as true-to-type. Based on the results exchange of plant material will be organized between the partners of the German Fruit Genebank in order to duplicate the cultivars within the established fruit-specific networks and fulfil the aim of the cooperation agreement. The German Fruit Genebank is represented at the web site www.deutsche-genbank-obst.de, including the database of the cultivars and acces­sion data as focal point. Data from systematic characterization and evaluation along with photographs will be uploaded for all the cultivars preserved in this decentralized network.
