Title of the Project
Field trial program for the testing of genetilcally modified maize tolerant to glyphosate herbicide (E5846.49.7.12 and E5846.53.9.4)

Proposed period of release:
01/04/2005 to 31/12/2008

Name of the Institute(s) or Company(ies)
Pioneer Hi-Bred Hungary Ltd., ;

3. Is the same GMPt release planned elsewhere in the Community?

2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
These maize varieties have been genetically modified to tolerate application of glyphosate herbicide, which allows the farmers to use a broad-spectrum, non-selective, systemic herbicide for the weeding of the maize fields.

Genetic modification

3. Type of genetic modification:

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
The introduced gene is the gat gene from Bacillus sp, providing tolerance to glyphosate herbicide, along with the regulatory components necessary for expression.

6. Brief description of the method used for the genetic modification:
The genetic modification was done using Agrobacterium mediated transformation method to introduce the DNA insert into the maize genome. The T-DNA on the Ti plasmid has been replaced by the construction containing the gat gene along with the regulatory components necessary for expression.

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:
Several types of trials will be carried out, such as trials to evaluate the nutrient composition profile, protein expression, agronomic behavior and tolerance to glyphosate of the genetically modified varieties in comparison with their non-genetically modified equivalents; to evaluate the residual behavior of glyphosate; to collect data on the agronomic value, and other trials in view of registration on the National List of Hungary.

2. Geographical location of the site:
In 2005, the location of the release sites will be as follows:

Country Fejér:
Enying, Agrár Rt. B-2 tábla
Füle, Búzakalász Mezőgazdasági Szövetkezet, F-14 tábla

Country Pest:
Sóskút, Sóskút Fruct Gyümölcstermelő Kft, hrsz. 0106

3. Size of the site (m2):
Each trial site in 2005 will have up to 600 m2 sown with each genetically modified plant, the total surface area taken up by the trials (all varieties and borders included) being higher. In the following years, up to 6 field trials could be sown, each with up to 3000 m2 of each genetically modified plant.

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:
Since 2003, field trials have already been conducted at several locations in Hawaii, USA and Chile with these genetically modified maize and no environmental problems were reported for these trials.

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 maize tolerant to glyphosate herbicide 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:
Seed dispersal of individual kernels does not generally occur. They are fixed on a cob and enclosed in many husks that protect the seeds from outside contact. 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.
In case of any emergency, the trial could be stopped by application of a non-selective herbicide other than glyphosate or by mechanical destruction, and incorporation into the soil.
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.
Volunteer maize will be monitored during the following year in order to ensure their destruction, if needed.
No commercial maize will be cultivated in the trial site 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 to this release.
