Naktuinbouw hosted UPOV Technical Working Party Meeting (TWO) for ornamental plants

News publication date: 24 June 2021

The UPOV Technical Working Party Meeting (TWO) for ornamental plants took place from 7 to 11 June. The meeting was hosted by Naktuinbouw. Naktuinbouw colleagues opened the session and gave a series of presentations. Due to the travel restrictions imposed by Covid-19, the meeting was not physically held in Roelofarendsveen, but took place online.

The agenda included the necessary revisions of guidelines

These amendments bring the guidelines back in line with the requirements of DUS testing. Naktuinbouw was in charge of revising the documents for Statice and Amaryllis, both of which will be continued next year. In addition, Naktuinbouw researchers provided input for the guidelines for Anthurium and Zinnia in particular. These guidelines were shared beforehand by the Leading Experts and input was collected. This approach ensures the process of discussing the guidelines proceeds smoothly. There were relatively few discussions during the meeting.

Characteristics were clarified, deleted and supplemented

During this revision, amendments were also made for the reference varieties. This ensures the guidelines remain usable and testing can be performed in a uniform way.

Revisions concerning the following crops are planned for next year:

  • Eucalyptus (Eucalyptus L’Hér.) (Partial revision)       TG/296/1
  • Gentian (Gentiana L.) (Revision)                                   TG/145/2
  • Ginkgo (Gingko biloba L.)                                               New
  • Helleborus (Helleborus L.)                                              New
  • Leucanthemum Mill.                                                       New
  • Pot Azalea (Rhododendron simsii Planch.) (Revision)    TG/140/4 Corr.

The future

An important subject was also: what do we do in the future? Should we continue organising our meetings online, or – if we can meet again live – is a combination a good idea? To ensure more experts can contribute to the meetings, it could be worthwhile holding certain parts of the meeting online. However, the ‘live’ coffee breaks are also an important networking moment. The following session of TWO will take place at the BundesSortenAmbt in Hanover next year.
