Rose tree/bush resources are managed in France by a cooperative network of partners : conservators of public or private establishments, representatives of the sector, and institutes concerned by the resources. The modus operandi is described in a Charter and internal regulations. The members of the network agree not only to make their genetic resources available and circulate them, but contribute towards maintaining and assessing them too.

Management applies to cultivated rose plants as well as old and wild forms and related species...
The objective of the network is thus the long-term management of a National Collection available for exchange or use.

Conservation and storage

As rose trees or bushes planted in conservatory rose-gardens ; 2 plants per accession. Long-term bank used as active and back-up banks (2 different locations).

Regeneration

Every 15 to 20 years by grafting or cuttings.

Distribution

Providing cuttings and scions.

Evaluation and characterisation of genetic resources

The conservators conduct the evaluations and characterisations laid down according to the programmes approved by the network. Evaluation based on the descriptors defined by the Groupe National Rosier : National Rose Group. Reference to the UPOV descriptors (International Union for the Protection of New Varieties of Plants).
The Rosa database is congruent with the European Rosa database.
