The apple collection has a special status since it is the only field collection of CGN. The collection is maintained as trees in an orchard at the Experimental Station Randwijk. Requests for scions can be made through the website. The collection consists of old varieties grown in the Netherlands and research material from former institutes, merged in Wageningen University & Research. The first old apple varieties were already collected in 1976 as an effort to preserve varieties which were no longer used in commercial production.
