2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
The genetically modified 59122x1507xNK603
(DAS-59122-7xDAS-Ř15Ř7-1xMON-ŘŘ60Ř3-6) maize varieties that will
be tested in these field trials are resistant to certain
Coleopteran insects, such as Western corn rootworm (Diabrotica
virgifera virgifera), and certain Lepidopteran insects, such as
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 59122 maize, 1507 maize and NK603 maize (from
Monsanto).
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:
59122x1507xNK603 maize contains the following genetic
elements:
- 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.
- 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 cp4epsps genes from Agrobacterium sp. strain CP4 that
confer tolerance to glyphosate herbicide, from NK603 maize.
All these genes have been introduced in the corresponding maize
along with their regulatory components necessary for expression.
6. Brief description of the method used for the genetic
modification:
No genetic modification was made on the 59122x1507xNK603
maize varieties directly: they were derived through traditional
breeding methods between progeny of the genetically modified
59122, 1507 and NK603 maize.
59122 maize was genetically modified using Agrobacterium
transformation method. 1507 maize was genetically modified using
a particle acceleration method. NK603 maize was genetically
modified by Monsanto using a 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:
Several types of trials will be carried out, such as trials
for protein expression ananlyses, effects on non-target
organisms, herbicide residue analyses, trials for elimination of
volunteers in rotational crops, agronomic value and insect
resistance, and other trials in view of registration on the
national List of Hungary.
2. Geographical location of the site:
Pioneer Hi-Bred Magyarország Kft. is going to set in the
trials in two counties in three locations. The trials will be in
county Fejér and Pest.
County Fejér:
Enying, Agrár Rt. B-2 tábla
Füle, Búzakalász Mezőgazdasági Szövetkezet, F-14 tábla
County Pest:
Sóskút, Sóskút Fruct Gyümölcstermelő Kft., hrsz. 0106
3. Size of the site (m2):
Each of the three trial sites in 2005 will have up to 8000 m2
sown with the particular genetically modified plants, the totel
surface area taken up by the trials (all 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:
Many field trials have already been conducted at several
locations across maize growing regions in North America, South
America and Europe and no environmental problems were reported
for these trials. The transgenic plants were indistinguishable
from the non-genetically modified maize plants except for
showing resistance to certain Coleopteran insects, such as
Western corn rootworm, and certain Lepidopteran insects such as
European corn borer and showing tolerance when glufosinate and
glyphosate herbicides were 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 Coleopteran and 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 200-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
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 on key
non-target arthropod populations, of the cultivation of
insect-resistant 59122x1507xNK603 maize hybrids, in comparison
with the cultivation of non-transgenic equivalent maize hybrids
treated with chemical insecticide and untreated. |
