Genetically modified plant
Complete name of the recipient or parental plant(s)
vulgaris var. saccharifera
Different conventional breeding lines
2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
The traits that are introduced provides;
Tolerance to the herbicide glyphosate, known under the trademark Roundup®. The tolerance is mediated by the introduced epsps gene.
Resistance to virus disease Rhizomania. The gene comes from Beet Necrotic Yellow Vein virus, which in the plant reduces the formation of the virus
The genes have been introduced individually and have then been crossed together sexually.
The selectable marker phosphomannose isomerase (PMI) has been used in the GM RZ 13 line. PMI results in a positive selection of cells with the PMI-gene.
3. Type of genetic modification:
In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
Each genetic element was transferred and inserted at a single locus.
The stacked event will contain 3 genes, i.e. epsps, RZM and PMI. Epsps provides tolerance to glyphosate, RZM provides resistance to Rhizomania and PMI was used a selectable marker.

6. Brief description of the method used for the genetic modification:
Disarmed Agrobacterium tumefaciens plant transformation system was used to produce events RR H7-1 and GM RZ 13. This delivery system is well documented to transfer and stably integrate transferred DNA (T-DNA) into a plant nuclear chromosome (White, 1989; Howard et al., 1990). The transformation was conducted using conventional diploid fertile sugar beet ines.
The sugar beet lines, with the different traits, were crossed together sexually.
7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
1. Purpose of the release:
The purpose of the release is to evaluate the level of weed control, virus control and agronomical performance in different breeding materials.
2. Geographical location of the site:
The release will take place in Landskrona, Helsingborg, Svalöv, Simrishamn, Kävlinge and Kristianstad
3. Size of the site (m2):
The sites of releases will be not more than 20 000m2. This area includes the GM plants, the non-GM control plants, and the surrounding area that is not cultivated.
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:
RR H7-1. The same event has been tested in field trials in EU since 1995 (by another applicant) and by Syngenta since 2005. No negative effects on human health or on the environment have been recorded. The event is also deregulated for cultivation in USA and Canada. Also for food and feed the event is deregulated in several countries. The event has received a positive EFSA opinion (EFSA, 2006) and is fully approved for food and feed in the EU (Commission Decision 2007/692/EC).
GM RZ 13 has been tested in Sweden since 2004 and in USA since 2002. No negative effects on the environment or on human health have been recorded.
When crossed together, no negative effects are anticipated.
Environmental Impact and Risk Management
Summary of the potential environmental impact from the release of the GMPts:
The intended effect of the modification is increased resistance to Rhizomania and tolerance to a specific herbicide. This may confer a selective advantage to the plant during the growth cycle but it is not anticipated to affect the agronomic characteristics that lead to selective advantage in natural environments.
Management measures (see Section E) are taken to reduce the potential release in the environment. Therefore, even though the introduced traits could confer a selective advantage to the sugar beet stacks, the risk for the GM sugar beet stacks to escape outside the release site or persist in the field is considered negligible.
No significant environmental benefits are expected from these field trials.
Brief description of any measures taken for the management of risks:
A number of measures will be taken to minimise any potential risk with this field release:
- a tight control will be enforced during drilling and harvest, to ensure that no plant escapes outside the release site,
- the drilling machine will go through a careful cleaning procedure after the drilling is finished,
- drilling will be performed by dedicated personnel that has gone through a special training for the handling of GM material,
- the GM sugar beet will not be allowed to bolt and shed pollen. Any bolting plants will be removed before pollen is released.
- selected roots will be transported to Syngenta site for sugar and quality analyses.
- all transport will be performed by dedicated personnel that has gone through a special training for the handling of GM material
- Transport of seeds and roots will take place in closed containers or boxes.
- at the end of the trial, the plants will be ploughed into the soil. This will destroy the plants and minimise the potential for regeneration of a sugar beet plant in the following spring,
- monitoring will be done during one year after the trial. A monocot crop will be grown on the release site during this year. The monocot crop will be sprayed with a herbicide that controls dicots (including sugar beet). Thus, any sugar beet that were not destroyed by the ploughing, and survived the below-zero temperatures of the winter, will be controlled by the herbicide used in the monocot crop. The site will be visited minimum 2 times during this year to check for and eliminate if necessary, any surviving sugar beet.
Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The purpose of this release is to evaluate weed control efficacy, Rhizomania control and agronomical performance in different plant breeding material, not to gain new data on the environmental and human health impact of the release.
