2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
The genetically modified 1507xNK603 maize varieties that will
be tested in these field trials are resistant to certain
Lepidopteran insects, such as the European corn borer (Ostrinia
nubilalis) and can tolerate the use of glufosinate-ammonium and
glyphosate herbicides for the weeding of maize field. This maize
was derived through traditional breeding methods between progeny
of the genetically modified 1507 maize, which is resistant to
certain lepidopteran insects and tolerant to glufosinate
herbicide, and NK603 maize (from Monsanto), which is tolerant to
glyphosate herbicide.
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:
1507xNK603 maize contains the following genetic elements:
- the cry1F gene from Bacillus thuringiensis var. aizawai that
confers resistance to certain Lepidopteran insects, such as
Ostrinia nubilalis,
- the pat gene from Streptomyces viridochromogenes that confers
tolerance to glufosinate-ammonium herbicide
- the cp4epsps genes from Agrobacterium sp. strain CP4 that
confer tolerance to glyphosate herbicide.
All these genes have been introduced with only their regulatory
components necessary for expression in maize plant.
6. Brief description of the method used for the genetic
modification:
No genetic modification was made on the 1507xNK603 maize
varieties directly: they were derived through traditional
breeding methods between progeny of the genetically modified
1507 maize and NK603 maize.
1507 maize and NK603 maize (from Monsanto) were genetically
modified using the particle acceleration 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:
Purpose of the release is to evaluate the impact of the
cultivation of 1507xNK603 maize hybrids on key non-target
anthropod populations, in comparison with the cultivation of
non-transgenic equivalent maize hybrids treated with chemical
insecticide and untreated.
2. Geographical location of the site:
In 2006, the location of the release sites will be as
follows:
Country Pest:
Sóskút, Sóskút Fruct Gyümölcstermelő Kft, hrsz. 0106
3. Size of the site (m2):
There will be one site of release. The dissemination of
1507xNK603 maize will cover up to 7500 m2 at the site of
release. This dissemination will be included in a field trial
that will also contain non-genetically modified maize and other
genetically modified maize notified by the same notifier under
other dossiers.
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:
Many field trials have already been conducted at several
locations and no environmental problems were reported for these
trials. The transgenic plants behaved as conventional maize
hybrids. They were indistinguishable from the non-genetically
modified maize plants except for showing resistance to
Lepidopteran insects such as European Corn Borer, as well as
showing tolerance when glufosinate and glyphosate herbicides
have been applied, traits due to the genetic modifications.
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 resistant
to certain Lepidopteran insects and tolerant to glufosinate and
glyphosate herbicides 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 500-meter isolation distance
with any other non-experimental maize crop. In addition, the
trial will be surrounded by four border rows of conventional
maize of a similar relative maturity that will be also destroyed
at the end of the release.
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 glufosinate
and 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:
Trials for effects on Non-Target Organisms:
The purpose of the release is to evaluate the impact of the
cultivation of insect-resistant 1507xNK603 maize hybrids on key
non-target arthropod populations, in comparison with the
cultivation of non-transgenic equivalent maize hybrids treated
with chemical insecticide and untreated.
