2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
- improved resistance to Phytophthora infestans
- tolerance to Imidazolinone herbicides, mediated by the ahas gene as selectable marker 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.
- ahas gene, Arabidopsis thaliana, imidazolinone tolerance in plant material.
- promoter and terminator from nopaline synthase gene, Agrobacterium tumefaciens, gene regulation.
- resistance genes Rpi-blb1 and Rpi-blb2, Solanum bulbocastanum, with endogenous promoters and terminators for improved resistance to Phytophthora 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 using a binary vector system.

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:
The purpose of the trial with the genetically modified potato lines with an improved resistance to Phytophthora infestans is, under field conditions,
- to generate data on agronomical performance
- to evaluate the agricultural and industrial value,
- to produce seed potatoes for following year field trials and cultivations.

2. Geographical location of the site:
Field trials and seed multiplication may be considered in Boden, Halmstad, Haparanda, Kristianstad, Lidköping, Lomma, Skara, Vara, Piteå, Luleå, Umeå and Övertorneå municipalities.

3. Size of the site (m2):
The total annual area will not exceed 50 ha.

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:
Releases of the same potato plants have been conducted in the Netherlands,Sweden, the Czech Republic, United Kingdom and Germany. No adverse impactson the environment or human health have been recorded in any of the trials.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The genetically modified potato lines contain two R-genes, Rpi-blb1 and Rpi-blb2, from Solanum bulbocastanum for conferring improved resistance to Phytophthora infestans. Many conventional potato varieties also contain additional R-genes that have been introgressed from wild Solanum species. An intended effect of the introduced trait is an increased performance in potato fields exposed to Phytophthora infestans. This possible selective advantage, however, is of importance only in the agricultural field, and will not be decisive for the survivability in the surrounding environment. The ahas gene expressed in the potato plants imparts tolerance to the herbicidal active substance Imazamox (Imidazolinone herbicide) to the shoots during the selection process in cell culture. This confers no selective advantage in the field or outside the field since Imidazolinone herbicides are not approved for use on crops in Sweden and since no field tolerance is expected in the potato plants. No difference with respect to persistence in agriculturally utilized habitats or invasiveness into natural habitats as compared to conventional potato varieties is expected. Through the measures that are taken during the release, isolation distance from other cultivated potatoes, and absence of crossable wild species, the possibility of any gene transfer can be virtually ruled out. Even in the very improbable event that pollen were to be transferred to a potato plant outside the trial, no consequences are to be expected, since agricultural potato propagation takes place via tubers and not via seeds. The interactions of the genetically modified potato line with non-target organisms and the effects resulting from this will be comparable to those with conventional potato varieties. Furthermore, no toxic or allergenic effects are expected on the basis of the improved resistance to Phytophthora infestans or the expressed AHAS protein. No effects on biogeochemical processes are expected, other than those which apply also to conventional potatoes.

Brief description of any measures taken for the management of risks:
- Isolation distance: 10 m
- Careful harvest to avoid volunteers
- Transportation in labeled containers in separate vehicles, closed containers or double closed sacks if transportation with other material
- Adjusted crop rotation, no other potato crop for two additional years
- Post harvest monitoring and destruction/controlling of any volunteers
- Complete destruction of plant waste material

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
