Samples of 100-200 seeds are made available to users for the purpose of food and agriculture under the terms of the standard material transfer agreement (sMTA). Plant breeding companies and research institutes are the main users of CGN’s spinach collection.

Spinach belongs to CGN’s most requested collections. Between 1988 and July 2015, CGN has distributed a total number of 11,693 spinach seed samples for external use. This number corresponds to an average distribution of more than 400 seed samples per year and to approximately 25 times the current collection size of 467 accessions. The collection has proven its value for crop improvement as novel disease resistances found in CGN accessions have formed the basis for the development of new cultivars.
