2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
- inhibition of granulebound starch synthase (GBSS), which yields a higher fraction of amylopectin in the starch

- marker gene ahas (imidazolinone tolerance) as selection gene to identify transgenic cells in tissue culture

Genetic modification

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:
T-DNA borders, pTiT37, for incorporation into plant chromosome.
Recombinant ahas gene, A. thaliana, imidazolinone tolerance in plant material.
Promoter and polyadenylation sequence from nopaline synthase gene, A. tumefaciens, gene regulation.
Inverted repeat fragment of gbss gene, S. tuberosum, inhibition of amylose synthesis.
Regulated by gbss promoter, S. tuberosum, and polyadenylation sequence from nopaline synthase gene, A. tumefaciens.

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 traits
- Investigate the agricultural and industrial value of the modified lines.
- Produce potato tubers for laboratory analyses.
- Produce seed potatoes for future trials.

2. Geographical location of the site:
Landskrona, Halmstad, Kristianstad, Gotland, Alvesta, Skara, Vara, Luleå and Robertsfors communities.

3. Size of the site (m2):
Max 50 000 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 adverse impacts on the environment or human health have been recorded for other potato lines with ahas gene in previous field trials in Sweden since 2002 or with increased amylopectin content since 1993.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The genetically modified potato lines show a shift of the tuber starch composition to amylopectin. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats compared to conventional potato varieties is expected. Nor is it expected that a selective advantage or disadvantage is conferred to the GM lines via the introduced traits. 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 elevated levels of amylopectin, nor from the ahas gene. Measures in place under current field trial practice will safeguard that all tuber 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. The GM potato lines will be cultivated under conventional agricultural practices.

Brief description of any measures taken for the management of risks:
- isolation distance: 20 m for trials and according to the seed production regulation for seed production
- careful harvest to avoid volunteers
- transportation in specific vehicles, closed containers or double sacks
- adjusted crop rotation: trials: fallow field the following year, no potato crop for one additional year; seed production: no potato crop for the following two years
- 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
