22.01.2018: Initial results of the field trial on GM wheat with improved powdery mildew resistance, running since 2014, were published in an international peer-reviewed journal. For more information see media release of the University of Zurich.
Field Trial with Fungus-Resistant Barley of the University of Zurich Authorised
13.6.2019: End of 2018, University of Zurich submitted to FOEN an application for field trials with genetically modified barley to which a wheat fungal resistance gene was introduced. The aim of the trial is to gain insights into how theses transgenic barley lines behave under field conditions, in particular concerning their fungal resistance. The first sowing is planned for spring 2020.
Continuation of Field Trials with Powdery Mildew-Resistant Wheat of the University of Zurich is authorised
University of Zurich Plans Field Trials with Transgenic Corn and Barley on the Protected Site
29.01.2019: Plant researchers at the University of Zurich have developed transgenic corn and barley lines with improved resistance against several fungal diseases thanks to the wheat resistance gene Lr34. Following successful tests in the greenhouse, the researchers are now planning to carry out field trials at the Agroscope site in Zurich-Reckenholz. It is planned to start the field trials in Spring 2019. The applications for the permits were submitted to the Federal Office for the Environment.
University of Zurich Applies for Continuation of Field Trials with Powdery Mildew-Resistant Wheat
13.11.2018: Since 2014, University of Zurich (UZH) researchers have been conducting field trials on the Protected Site at Agroscope Reckenholz with genetically modified (GM) wheat with improved powdery-mildew resistance conferred by the Pm3 resistance gene from wheat (description of the project). The release authorisation, which is a prerequisite for field trials with GM plants, expires at the end of this year. In late October 2018, the UZH submitted a new request for release to the Federal Office for the Environment (FOEN) (information page of FOEN) which would enable it to carry out the trials for a further five years. The UZH proposes to implement the same safety measures imposed on them by the FOEN in the previous field trial.
The aim of the new trials is to investigate the offspring of a cross between the wheat lines studied to date which bear a combination of three or four Pm3 variants (‘alleles’), as well as lines with one of three Pm3 variants that have not been studied under field conditions yet. An additional aim is to characterise in the field wheat plants carrying the two Pm3 variants from rye, Pm8 and Pm17. These two genes, already introduced into wheat by classical breeding in the last century, are to be investigated individually or in combination, also with Pm3 variants from wheat. The aim of the recently requested field trial is an improved understanding of the plant immune system. Thus, the planned trial will form part of the basic research conducted at the UZH.
