2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
DP-Ø9814Ø-6 maize, referred to as 98140 maize hereafter, has been genetically modified so that it can tolerate application of herbicides containing glyphosate and a range of ALS-inhibiting herbicides such as sulfonylureas for the weeding of the maize crop.

Genetic modification

3. Type of genetic modification:
Insertion;

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
98140 maize has been genetically modified by insertion of the synthetic glyphosate-N-acetyltransferase (gat4621) gene and a modified maize acetolactate synthase (zm-hra) gene, along with the necessary regulatory elements for gene expression in the maize plant.
The gat4621 gene encodes the GAT4621 protein, which was derived from the soil bacterium Bacillus licheniformis, and confers tolerance to herbicides containing glyphosate. The zm-hra gene encodes the ZM-HRA protein and confers tolerance to a range of ALS-inhibiting herbicides such as sulfonylureas.


6. Brief description of the method used for the genetic modification:
98140 maize was genetically modified using the Agrobacterium-mediated transformation method.

7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
Not applicable.

Experimental Release

1. Purpose of the release:
The purpose of the trial program is to evaluate 98140 maize, with or without applications of glyphosate and ALS-inhibiting herbicides such as sulfonylureas.

2. Geographical location of the site:
Ivanovice na Hane, Jihomoravsky region; Caslav, Stredocesky region; Nechanice, Kralovehradecky region; Kromeriz, Zlinsky region; from 2009 on plus one site in Prague.

3. Size of the site (m2):
Each trial site will have up to 20000 m2 sown with 98140 maize the total surface area taken up by the release (non-GM varieties and borders included) being higher.

4. Relevant data regarding previous releases carried out with the same GM-plant, if any, specifically related to the potential environmental and human health impacts from the release:
Field trials have already been conducted at several locations across maize growing regions in North America, South America and European Union, and no environmental problems were reported for these trials. The transgenic plants appeared normal in all respects. They were indistinguishable from the non-genetically modified maize plants except for being tolerant to glyphosate and ALS-inhibiting herbicides such as sulfonylureas, traits due to the genetic modification.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
No risks to human and animal health or the environment from the deliberate release of genetically modified 98140 maize, tolerant to glyphosate and a range of ALS-inhibiting herbicides such as sulfonylureas, are expected as per information contained in the environmental risk assessment included in the notification.

Brief description of any measures taken for the management of risks:
The shedding of pollen from the genetically modified plants will be controlled by maintaining a 200-meter isolation distance with any other non-experimental maize crop. In addition, the trial site will be surrounded by eight agronomic border rows of conventional maize of a similar maturity that will be also destroyed at the end of the release.
Grains are fixed on a cob and enclosed in many husks that protect the seeds from outside contact. Thus seed dispersal of individual kernels is not likely to occur. When a few seeds need to be collected for analysis; this will be done by sampling the whole ear and unused seeds will be destroyed.
At the end of the release, all remaining plant matter that has not been harvested for analyses will be destroyed by chopping and incorporating into the soil by a deep ploughing. No plant or plant product coming from the trials will enter the food or feed chains.
After the release, the plot will be visited regularly during the following year in order to ensure removal of maize volunteers, if any. Although volunteer maize cannot generally survive hard winter, maize volunteers, if any, will be monitored in order to ensure their destruction.
There will be no commercial maize grown on the same area of the field the following year.


Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
Not applicable.
