2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
The genetically modified 1507x59122 maize varieties are
resistant to certain Lepidopteran insects, such as the European
corn borer (Ostrinia nubilalis) and to certain Coleopteran
insects, such as the Western corn rootworm (Diabrotica virgifera
virgifera) and can tolerate the use of glufosinate-ammonium
herbicide for the weeding of maize field. This maize was derived
through traditional breeding methods between progeny of
genetically modified 1507 maize, which is resistant to certain
lepidopteran insects and tolerant to glufosinate herbicide, and
59122 maize, which is resistant to certain coleopteran insects
and tolerant to glufosinate 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:
1507x59122 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, and the pat gene from Streptomyces
viridochromogenes that confers tolerance to glufosinate-ammonium
herbicide, from 1507 maize
- the cry34Ab1 and cry35Ab1 genes from Bacillus thuringiensis
strain PS149B1 that confer resistance to certain Coleopteran
insects, such as Diabrotica virgifera virgifera, and the pat
gene from Streptomyces viridochromogenes that confers tolerance
to glufosinate-ammonium herbicide, from 59122 maize
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 1507x59122 maize
directly: it was derived through traditional breeding methods
between progeny of the genetically modified 1507 and 59122
maize.
1507 maize was genetically modified using a particle
acceleration method, 59122 maize was genetically modified using
Agrobacterium 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:
Purpose of the release is to evaluate the impact of the
cultivation of 1507x59122 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 site will be as follows:
County Pest:
Sóskút, Sóskút Fruct Gyümölcstermelő Kft., hrsz. 0106
3. Size of the site (m2):
There will be one site of release. The surface of genetically
modified maize plants that will be up to 4000 m˛. 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:
Field trials have already been conducted at different
locations across maize growing regions in North America, South
America and Europe, and no environmental problems were reported
for these trials. The transgenic maize plants were
indistinguishable from the non-genetically modified maize plants
except for showing resistance to certain Lepidopteran insects,
such as European corn borer, and to certain Coleopteran insects,
such as Western corn rootworm, and showing tolerance when
glufosinate herbicide was 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 and Coleopteran insects and tolerant to
glufosinate 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:
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 site 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
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. An
herbicide treatment (other than glufosinate) will be used in
order to ensure destruction if needed.
There will be no commercial maize grown on te same field 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 1507x59122 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.
