The history of the melon collection is analog to the CGN collections of tomato, pepper, eggplant and cucumber and described in the general page of the fruit vegetables. It was adopted in 2005, this more recently than the other fruit vegetables.
The collection of melon is small. It contains only accessions which could not be found in other collections; 17 accessions originate from the Netherlands. Part of the collection comes from the former IVT and about 30 accessions were collected during an IPGRI collection mission in Pakistan in 1981. In 2017 a collecting expedition took place in Uzbekistan which resulted in an additional 62 landraces which could be added to the collection. This resulted in a total of 141 accessions (March 2020) of which 79 accessions are presently available because regeneration is needed to meet CGN standards. The available collection comprises of 23 cultivars, 42 landraces mostly from Pakistan and Egypt and 14 accessions of unknown population type. Melon comes in many different types and can be sweet to sour.
