2. Description of the traits and characteristics which have
been introduced or modified, including marker genes and previous
modifications:
Oilseed rape plants have been transformed with the vector
pMON 17237. The genes, which have been introduced, confer to the
oilseed rape plant tolerance to glyphosate, the active
ingredient of the herbicide Roundup.There have been no previous
genetic modifications of the parental organism.
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:
A disarmed plasmid from an Agrobacterium species has been
used as a vector. The vector pMON 17237 contains Roundup
tolerance genes, border sequences, replication sequences and
virulence genes.
The sequence to be inserted is situated between the right and
left borders of the plasmid and contains combinations of the
following genes:
1. A gene fusion between the chloroplast transit peptide
sequence from the Arabidopsis thaliana EPSPS gene and a sequence
that encodes an EPSPS enzyme similar to that of Agrobacterium
sp. strain CP4. This enzyme confers Roundup tolerance in the
plant.
2. A gene fusion between a transit peptide gene derived from the
small subunit of Arabidopsis thaliana chloroplast transite
peptide of ribulose biphosphate carboxylase and a synthetic gene
sequence that encodes the glyphosate oxidoreductase enzyme
(GOX). This enzyme catalyses glyphosate degradation, thus
conferring Roundup tolerance in the plants.
6. Brief description of the method used for the genetic
modification:
Oilseed rape plant tissue has been transformed with
Agrobacterium tumefasciens containing the disarmed plasmid pMON
17237.
7. If the recipient or parental plant is a forest tree
species, describe ways and extent of dissemination and specific
factors affecting dissemination:

Experimental Release
1. Purpose of the release:
The aim of this project is to develop breeding lines with
Roundup tolerance, suitable for the North American market. Notes
of the agronomic performance will be made for the plots.
Selected plots will be used for crosses, selfpollination and
bulk harvest.
2. Geographical location of the site:
The site(s) will be in one or several of the rural districts
Svalöv, Landskrona, Klippan, Höör, Hässleholm and
Perstorp, Sweden, in each year.
The exact location will be submitted to the competent authority
each year.
3. Size of the site (m2):
Maximum 200 000 m2 each year.
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:
The same GM plant has been used in confined field trials in
Sweden 1998 – 2003
(SJV dnr 22 10027/97, 22 6885/98). Staff from SW has worked in
the fields throughout the growing seasons. The crop has been
equivalent to other field trials, except for the tolerance to
glyphosate. No observation has been made which would indicate
any risk to human health, animals or environment in general.
Environmental Impact
and Risk Management
Summary of the potential
environmental impact from the release of the GMPts:
The genetically modified plant is substantially equivalent to
normal breeding material of spring oilseed rape. Plants having
the introduced character herbicide tolerance will only have a
selective advantage if the herbicide is applied. Natural
environments are not treated with herbicide and in the
agricultural environment the plants will only have an advantage
if the field is sprayed with the herbicide in question, in this
case a herbicide with the active substance glyphosate.
An agronomic and economic assessment of herbicide tolerant
rapeseed in Canada,
made by Canola Council of Canada (2001) indicates that the
transgenic herbicide tolerant varieties allow growers to use
better soil management practices, which contribute to soil
conservation and saved 31 million litres of fuel.
Brief description of any measures taken for the management of
risks:
The distance to other fields will be at least 500 m. The
sowing machine used for the modified seed will be emptied and
cleaned before it is removed from the field. Remaining seed from
the sowing machine will be destroyed. The fields will be
surrounded by 8-m wide borders of unmodified male sterile
oilseed rape to minimise spread of pollen. All volunteer plants
of oilseed rape and closely related cruciferous plants, which
might grow within 50 m from the outer part of the border, will
be destroyed before the flowering. Beehives used will be closed
for 48 hours to have the bees cleaned from viable GMO-pollen.
Combines that have been used for harvest of selected or
discarded plots will be cleaned before they are removed from the
field. The trial sites will be examined for volunteer plants
during the following four years. Plants discovered will be
destroyed before flowering. If it is a small number of plants
they will be mechanically removed and larger numbers will be
sprayed with effective herbicides.
After harvest spilled seed will be left on the ground to
germinate. During the autumn shallow cultivation will be made.
No ploughing, to minimise the risk of seed being ploughed down
before it has had a chance to germinate. None of the following
for crops will be oilseed rape.
Discarded seed will be taken care of for destruction by burning.
Material harvested for breeding purpose will be clearly marked
‘GMO’. When seed is no longer needed it will be destroyed. Straw
and other organic debris will be cut and mixed with soil in the
following cultivation.
This site will be marked on a map in such a way that it will be
easily found in the coming years. The site will be inspected
regularly from sowing to harvest. Observations will be
registered. During the following four years the site will be
inspected regularly from sowing to harvest and volunteer plants
destroyed.
If the trial has to be discarded because of unforeseen reasons,
the plant material will be destroyed by chemical and mechanical
treatment. The site will be inspected for the presence of
volunteer plants the following years and such plants will be
destroyed.

data on environmental and human health impact from the release:
