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

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:
Insertion;
4. 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 The T-DNA on the Ti plasmid has been replaced
by the construction containing the gat gene along with the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. |
