B/CH/25/02 (B25002): Application to release a genetically modified potato strain with improved potato late blight resistance for experimental purposes
Submitted 9 December 2025
Publication in the Federal Law Gazette (BBI):
Applicant: Agroscope
Organism: potato
Property: Resistance to late blight of potato
Genetic modification:
- Late blight resistance gene
- Native promoter of the gene Rpi-chc1;
- Resistance gene Rpi-chc1 from Solanum chacoense;
- Native terminator of the gene Rpi-chc1
- Marker gene
No marker gene was introduced
Purpose of experiment:
- Characterisation of the cisgenic potato line under field conditions, in particular of its resistance against local strains of the potato late blight pathogen; this is in preparation of further releases for the NRP 84 project CRISPS with this line serving as control;
- Clarification of biosafety-related aspects of the release of the cisgenic potato line.
Location of experiment:
- Protected site of Agroscope in Zurich, Reckenholz, Reckenholzstrasse 191, 8046 Zurich
Duration of experiment: spring 2026 to autumn 2030
Legal basis
- Gene Technology Act (GTA)
- Release Ordinance (RO)
