Ornamental, Aromatic & Medicinal Plant Expertise

GEVES conducts field trials for plant variety protection and seed testing across a wide range of ornamental, aromatic and medicinal species.

DUS Expertise for Plant Variety Protection

GEVES, the French examination office, performs Distinction-Uniformity-Stability (DUS) testing that is legally required for the protection of ornamental and aromatic varieties. GEVES receives requests from INOV (French protection), the CPVO (EU protection system) or other EU offices for DUS testing. Candidate varieties are cultivated in open fields or under cover, and compared to well-known varieties in order to guarantee a precise observation of the required criteria.

Variety Testing at GEVES

  • Testing conditions:

GEVES carries out testing at its experimental stations which are representative of different soil and climatic conditions. This way, we can adapt to changes in climate and different genera. These stations are close to the main ornamental production areas in France (Loire Valley, West of France, Mediterranean area) and work in collaboration with the sector and technical institutes.

  • Regulatory and scientific expertise:

    • Member of the French CTPS committee for medicinal, aromatic and ornamental plants
    • Strong scientific expertise in cooperation with INRA, GEVES’s founding partner
    • Leading expert at the UPOV and the CPVO.
  • In vivo permanent reference collections for different genera: Hydrangea, Chrysanthemum, Lavandula, Lagerstroemia, Oleander, Buddleia, Berberis, Abelia, Weigelia, Pyracantha, Forsythia, Thyme, Mint…
  • Partnership building with city arboretums for the conservation of reference collections.

 

 

 

What is the purpose of providing material to a reference collection? 

To maintain an up-to-date reference collection, GEVES regularly asks professionals to provide a small number of plant varieties.

Including your varieties in the reference collection has dual benefits:

  • To guarantee the distinction of a candidate variety to well-known varieties, whether or not they are protected,
  • To support third-party cases of fraud or dispute.

Seed Testing

In support of the seed sector, the GEVES laboratories have developed a specific set of analyses for ornamental and aromatic seeds:

 

  • Physical analysis
    • Specific purity and determination of foreign species
    • Micro-cleaning
  • Germination capacity
    • Germination of seeds in optimal or unfavourable conditions
    • Germination of bulblets
    • Seed viability tests
  • Variety resistance tests - e.g. basil resistance to Peronospora behlbarii
  • Seed health
    • Nematology on bulbs, bulblets, rootstocks, and tubers
    • Virology on cyclamen
    • Bacteriology: dill, coriander, parsley
    • Mycology: dill, basil, lavender, parsley
  • Tailored projects using genotyping and biochemistry
  •  R&D: Study and development of individual tailored projects

Conservation of Plant Genetic Resources

GEVES supports actors involved in the preservation of plant genetic material and collections. With the aim of creating a dynamic for the conservation of these resources, GEVES contains the National Coordination Structure for cultivated species and their crop wild relatives. Its key actions include:

  • Official recognition by the French state for managers of plant genetic resources collections
  • Identification of the national French collection which contains plant genetic resources of major interest for France
