2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
The genetically modified 59122xNK603 maize varieties that will be tested in these field trials are resistant to certain Coleopteran insects, such as the Western corn rootworm (Diabrotica virgifera virgifera) and can tolerate the use of glufosinate-ammonium and glyphosate herbicides for the weeding of maize field. This maize was derived through traditional breeding methods between progeny of genetically modified 59122 maize, which is resistant to certain coleopteran insects and tolerant to glufosinate herbicide, and NK603 maize (from Monsanto), which is tolerant to glyphosate herbicide.

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:
59122xNK603 maize contains the following genetic elements:
- the cry34Ab1 and cry35Ab1 genes from Bacillus thuringiensis strain PS149B1 that confer resistance to certain Coleopteran insects, such as Diabrotica virgifera virgifera, and the pat gene from Streptomyces viridochromogenes that confers tolerance to glufosinate-ammonium herbicide, from 59122 maize
- the cp4epsps genes from Agrobacterium sp. strain CP4 that confer tolerance to glyphosate herbicide, from NK603 maize
All these genes have been introduced with only their regulatory components necessary for expression.

6. Brief description of the method used for the genetic modification:
No genetic modification was made on the 59122xNK603 maize varieties directly: they were derived through traditional breeding methods between progeny of the genetically modified 59122 maize and NK603 maize.
59122 maize was genetically modified using Agrobacterium transformation method. NK603 maize was genetically modified by Monsanto using the particle acceleration method.

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:
Several types of trials are planned, to collect various maize tissue samples for protein expression analysis, to control maize volunteers with different herbicides, to evaluate the residual behavior of glufosinate and glyphosate in transgenic maize, to collect data on the agronomic value and insect resistance of transgenic maize varieties

2. Geographical location of the site:
The release is planned at the following locations in Spain in 2005:
- Aragón: Pastriz (Zaragoza), Gurrea de Gállego (Huesca).
- Cataluña: Alpicat (Lérida), Alguaire (Lérida).
- Madrid: Estremera (Madrid).
- Navarra: Fustiñana (Navarra)
- Castilla-La Mancha: Membrilla (Ciudad Real)

3. Size of the site (m2):
Each site in 2005 could have up to 600 m2 sown with the genetically modified maize concerned by this application (59122xNK603 maize), the total area taken up by the release (all varieties and borders included) being higher.
In the following years, there could have up to 5000 m² of the genetically modified maize subject of this notification sown per site, the total trial surface at each site (all varieties and borders included) being larger.

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:
Field trials have already been conducted at several locations across maize growing regions in North America, South America and Europe and no environmental problems were reported for these trials. The transgenic plants were indistinguishable from the non-genetically modified maize plants except for showing resistance to certain Coleopteran insects such as the Western corn rootworm and showing tolerance when glufosinate and glyphosate herbicides have been applied, traits due to the genetic modifications.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
No risks to human and animal health or the environment from the deliberate release of genetically modified maize resistant to certain Coleopteran insects and tolerant to glufosinate and glyphosate herbicides are expected, as per information contained in the environmental risk assessment included in the notification.

Brief description of any measures taken for the management of risks:
The shedding of pollen from the genetically modified plants will be controlled by maintaining a 200-meter isolation distance with any other non-experimental maize crop. In addition, the trial site will be surrounded by four border rows of conventional maize of a similar relative maturity that will be also destroyed at the end of the release.
Seed dispersal of individual kernels does not generally occur. They are fixed on a cob and enclosed in many husks that protect the seeds from outside contact. When a few seeds need to be collected for analysis; this will be done by sampling the whole ear and unused seeds will be destroyed.
In case of any emergency, the trial could be stopped by application of a non-selective herbicide, other than glufosinate and glyphosate, or by mechanical destruction, and incorporation into the soil.
At the end of the release, all remaining plant matter that has not been harvested for analyses will be destroyed by chopping and incorporating into the soil.
Volunteer maize will be monitored during the following year. An herbicide treatment (other than glufosinate and glyphosate) will be used in order to ensure destruction if needed.
There will be no commercial maize grown on the same field the following year.

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