Training course: Use of molecular markers in DUS studies

We regret to inform you that the Workshop “Use of molecular markers in DUS studies” scheduled to take place in March 2022 has been postponed due to the current COVID-19 situation. As the workshop aims to facilitate exchanges between participants and provide hands-on practical sessions, we believe a physical event would be more fruitful. We will consider new dates for the workshop when the situation improves and update this webpage accordingly. We are sorry for this cancellation and hope to see you at the rescheduled event.




29-31 March 2022 Postponed until 2023 due to the current COVID-19 situation


Aim of the workshop

A growing number of varieties are being submitted for DUS (Distinctness, Uniformity, and Stability) testing for Plants Breeder’s Rights and/or National Listing. Candidate varieties which are potentially similar to varieties of common knowledge, have to be grown side by side in trials. Field trials being increasingly resource demanding, there is an interest to reduce the number of varieties grown in DUS trials. How can the DUS system adapt to this increasing workload while keeping  the same level of performance? How can we optimise our use of variety collections for planting DUS field trials?

Molecular markers are a useful tool to help to improve quality and efficiency in DUS testing.

The Workshop is intended to instruct the participant on the theory and practices on molecular markers and their uses in DUS testing.


Contents overview

Lectures on:

  • Basic DNA techniques and genotyping method, data interpretation
  • Principle of DUS and practical DUS testing
  • UPOV guidelines
  • Use of molecular markers in the DUS study (Maize example)
  • Other applications of molecular markers
  • Pro and cons


Laboratory hands on sessions: following a maize sample through all the different steps of molecular analysis:

  • Sampling
  • DNA extraction
  • SNP assay on different platforms
  • Genotyping result, data interpretation


Complete programme coming soon


Target Group

Applicants should have a role in the variety registration process such as in an examination office or in an associated competent authority.

No prerequisite is required in molecular biology, or in DNA based molecular markers.
