2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
The GM-potato is characterized by a higher level of late blight resistance. Depending on the construct, the GM-potato contains the selection marker gene NPTII or AHAS, or is marker free.

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:
In this project different constructs are used which consist of different combinations of the following fragments:
- T-DNA borders from Agrobacterium tumefaciens for stable incorporation into the plant genome.
- The NPTII gene from Escherichia coli, to be used as selection marker.
- The AHAS gene from Arabidopsis, to be used as selection marker.
- Nopaline synthase promoter from Agrobacterium tumefaciens for regulation of NPTII or AHAS expression.
- Nopaline synthase terminator from Agrobacterium tumefaciens for regulation of NPTII or AHAS expression.
- Terminator Tg7 from Agrobacterium tumefaciens for regulation of NPTII expression.
- Rpi-genes, including original promoter and terminator, from tuber bearing Solanum species for late blight resistance.


6. Brief description of the method used for the genetic modification:
T-DNA was introduced into potato cultivars by Agrobacterium-mediated gene transfer technology using a binary vector system.

Experimental Release

1. Purpose of the release:
- Production of seed potatoes for future trials.
- Evaluation of late blight resistance under field conditions.
- Evaluation of the agricultural value of modified genotypes.


2. Geographical location of the site:
Municipalities: Aa en Hunze, Borger-Odoorn, Eemsmond, Coevorden, Rhenen, and Wageningen. All municipalities are situated in The Netherlands.

3. Size of the site (m2):
The size per site will be variable. The maximum size per site is 10,000 m2

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:
Similar GM-plants were grown in 2008 and 2009 (license IM 07-001). Compared to classical breeding stocks, no deviations of any kind were observed. Cultivars, derived by classical breeding methods, containing late blight resistance genes (Rpi-genes) are being cultivated for several decades without any negative impact on the environment or human health.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
The introduced resistance will not confer an increased selective advantage in natural environments compared to the effect of late blight resistance genes present in potato cultivars.

Brief description of any measures taken for the management of risks:
All handling of GM-plants and GMO fields will be done according to good agricultural practices.
- Transportation of potatoes will be done in boxes or bags in open containers.
- Crop rotation: no potato crop the following two years.
- Destruction of volunteers
- Destruction of waste material.


Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
All handling of GM-plants and GMO fields will be done according to good agricultural practices.
- Transportation of potatoes will be done in boxes or bags in open containers.
- Crop rotation: no potato crop the following two years.
- Destruction of volunteers
- Destruction of waste material.
