2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
- improved resistance to Phytophthora infestans
- marker gene nptII (kanamycin resistance) as selection gene to identify transgenic cells in tissue culture


Genetic modification

3. Type of genetic modification:
Insertion;

In case of insertion of genetic material, give the source and intended function of each constituent fragment of the region to be inserted:
T-DNA borders, pTiT37, for incorporation into plant chromosome.
NptII gene, Tn 5, kanamycin resistance in plant material.
Promoter and terminator from nopaline synthase gene, A. tumefaciens, gene regulation.
Resistance gene, Solanum bulbocastanum, with endogenous promoter and terminator for improved resistance to P. infestans


6. Brief description of the method used for the genetic modification:
Plasmid DNA was introduced into the potato lines by Agrobacterium-mediated gene transfer technology.

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:
- Investigate expression and stability of modified trait
- Investigate the agricultural value of the modified lines, especially resistance to P. infestans
- Produce seed potatoes for future trials.


2. Geographical location of the site:
Landskrona, Halmstad and Kristianstad communities.

3. Size of the site (m2):
Max 3 000 m2 in total

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:
No previous release.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The genetically modified potato lines show an improved resistance to Phytophthora infestans. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats compared to conventional potato varieties is expected. Due to the measures to be taken during the release (distance to or absence of cultivated and wild relatives) will the potential for gene transfer virtually be excluded. Interactions of the GM potato lines with non-target species and resulting effects will be comparable to those of conventional potato varieties. No toxic or allergenic effects are expected from the introduced resistance, nor from the nptII gene. Measures in place under current field trial practice will safeguard that all tubers and plant material is properly managed, harvested, stored, transported or disposed of to minimize contact to humans or animals. No effects are expected on biogeochemical processes.

Brief description of any measures taken for the management of risks:
- isolation distance: 20 m
- careful harvest to avoid volunteers
- transportation in specific vehicles, closed containers or double sacks
- adjusted crop rotation: fallow field the following year, no potato crop for one additional year
- destruction of waste material


Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
Not planned
