2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
Bt11 maize contains two genes introduced by genetic modification techniques:
· Glufosinate ammonium tolerance gene: pat (phosphinothricin-acetyl-transferase) under the control of the 35S promoter and the nos termination
· Insect resistance gene: cry1Ab, under the control of the 35S promoter and the
nos3’ termination region.

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:
· pat gene, isolated from Streptomyces viridochromogenes, gene encodes the enzyme phosphinothrycin acetyl transferase which catalyzes the conversion of glufosinate ammonium to an herbicidally inactive product.
· cry1Ab gene, isolated from Bacillus thuringiensis, encodes a Btk protein which protects the plant from damage by lepidopteran pests.

6. Brief description of the method used for the genetic modification:
The initial parental transformation of the maize line was accomplished through
the insertion of a fragment of the plasmid pZO1502. No DNA carrier was used.

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 liberation is to collect data of Bt11 maize varieties related to the technical inspection for the inscription of commercial varieties, required by Law 3/2000, of January 7th, the legal regime of the protection of the vegetal obtainings, and Law 11/1971, of seeds and plants of breeding ground.

With this purpose, tests of agronomic value will be made in the sites of Alforque (Zaragoza), L'Aldea (Tarragona), Deltebre (Tarragona), Fraga (Huesca), Lleida (Lleida), Sástago (Zaragoza), and Torres de Segre (Lleida); a nursery of parentals observation in the locality of Lleida; and a test of identification in Almodóvar of del Río (Córdoba).

2. Geographical location of the site:
- Alforque (Zaragoza)
- L’Aldea (Tarragona)
- Almodóvar del Río (Córdoba)
- Deltebre(Tarragona)
- Fraga (Huesca)
- Lleida (Lleida)
- Sástago (Zaragoza)
- Torres de Segre (Lleida)

3. Size of the site (m2):
- Alforque (Zaragoza): 2000 m2
- L’Aldea (Tarragona): 2000 m2
- Almodóvar del Río (Córdoba): 600 m2
- Deltebre (Tarragona): 2000 m2
- Lleida (Lleida): 3500 m2
- Fraga (Huesca): 2000 m2
- Sástago (Zaragoza): 2000 m2
- Torres de Segre (Lleida): 2000 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:
The European Food Safety Authority (EFSA) adopted on 20th April 2005 its favourable opinion about the evaluation of the maize Bt11 for cultivation. This Opinion was published in The EFSA Journal (2005) 213, 1-33: Opinion of the Scientific Panel on Genetically Modified Organisms on a request from the Commission related to the notification (Referente C/F/96/05.10) for the placing on the market of insect resistant genetically modified maize Bt11, for cultivation, feed and industrial processing, under Part C of Directive 2001/18/EC from Syngenta Seeds (Question No EFSA-Q-2004-012) Opinion adopted on 20 April 2005.
This Opinion can be consulted in the EFSA web site:
The Bt11 maize has been evaluated for its security by numerous authorities in the world. It has been approved for its culture and for its use for human and animal consumption in: U.S.A., Canada, Argentina, Japan, South Africa, Uruguay and Philippines. Exclusively for human and animal consumption it has been authorized in Switzerland, Australia, New Zealand, Korea, Taiwan, Russia, China and the European Union (E .U.)
The results confirm the safety of the culturing for the environment and the agronomic adjustment of the studied hybrids.
No environmental or human health negative impact has been reported during previous trials or during commercial cultivation of maize carrying the Bt11 trait.
Hence, no such impact is expected from this trial either.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
It is the specific and intended effect of the modification, that the use of Bt11 maize would have an immediate, direct effect on the populations of target pests in the fields with Bt11 maize (Ostrinia nubilalis and Sesamia nonagroides). It is also possible that in areas where the use of Bt11 maize leads to a reduction in the use of insecticides, an increase in generalist predators such as carabids and spiders could occur resulting in an
improved biological control of pest species (Head et al, 2001).
In addition, reduced insect damage may result in a reduction in Fusarium fungal
colonisation leading to an improvement in grain yield and quality.
A substantial number of field studies of non-target insect populations in Bt corn have been performed. To date no adverse effects of non-target invertebrates have been detected. (ABSTC, 2002)
In the EU, there are no indigenous species (non-target organisms), which rely
exclusively on maize pests for survival as symbionts, predators or pathogens, it is highly unlikely that the reduction in numbers of ECB or MCB in the maize fields will affect the population levels of these non-target organisms.
Maize has no wild relatives in the EU so the potential for gene transfer to sexually compatible plant species, other than maize, in the EU is zero.
There is no evidence to suggest that intact gene transfer occurs from a plant species to micro-organisms in the field situation.

Brief description of any measures taken for the management of risks:
o All the fields will be isolated by a distance of at least 220 m from other maize fields.
o All the fields will be surrounded by a border of 8 rows of conventional maize.
o The grain harvested from the trials will not be used for human food or animal
o Plant material remaining after harvest will be ploughed into the soil.
o The site will be monitored for one year after the release. During this year,
commercial maize will not be grown on the trial site. Any volunteer maize
appearing in the field will be eliminated before flowering.

Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The trials have been designed with the only purpose of collecting data related to the technical inspection of the maize hybrids destined to the Commercial Registry of the Varieties.
