As Requested by Breeder Organizations, UPOV CAJ Initiates Revision of UPOV EXN on Essentially Derive

For immediate release

Geneva/Hamburg, October 30 – at its 76th meeting, the UPOV Administrative and Legal Committee (CAJ) agreed to start the review process of the UPOV Explanatory Note (EXN) on Essentially Derived Varieties (EDV). The move, highly anticipated by the breeding sector, comes months after an alliance of breeder organizations raised concerns about the narrow EDV concept interpretation in the UPOV EXN.

UPOV CAJ first agreed to consider the revision at its 75th meeting in 2018, after CIOPORA, ISF and the U.S. delegation at UPOV stressed the shortcomings of the current EDV interpretation. On August 12, CIOPORA, CropLife, ISF, Euroseeds, APSA, AFSTA, and SAA submitted a joint letter to UPOV pointing out that the narrow approach to EDV concept may “... greatly endanger the breeding incentive and could possibly lead to a diminution of (...) breeding effort...”

The October 30 CAJ decision was made after breeders, including CIOPORA members, presented their views on the issue at the Seminar on the impact of policy on Essentially Derived Varieties (EDVs) on breeding strategy in the 76th CAJ meeting Geneva. The Seminar Chairman concluded that:

  • There is evidence that the current UPOV guidance does not reflect the breeders' common practice in understanding EDV;

  • The evolution of breeding techniques has created new opportunities/incentives for predominantly deriving varieties from initial varieties, more rapidly and at a lower cost.

  • The Seminar presentations and discussions indicated that the understanding and implementation of the EDV concept has a direct impact on the breeding strategy and, therefore, the UPOV guidance must be tuned to maximize the progress in breeding to benefit the society.

CIOPORA and the breeder organizations-signatories to the joint letter will closely monitor and participate in the revision process of the UPOV EXN on EDV to ensure that the EDV concept is sufficiently broadly defined and that clear and unambiguous rules are provided for the establishment of dependency between an EDV and its initial variety. In the breeders’ joint opinion, a new UPOV EXN on EDV version should clearly affirm that predominant derivation from an initial variety, as confirmed by a high genotypic conformity, is a key requirement for a variety to be considered an EDV, and that even important modifications in the characteristics of an initial variety do not automatically lead to a new variety escaping from being qualified as EDV.
