2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
The tested maize hybrids have been obtained by crossing three genetically modified parental lines: one parental line contains an insert providing resistance to certain Coleopteran insects and tolerance to glufosinate ammonium herbicide, other parental line contains an insert for resistance to certain Lepidopteran insects and tolerance to glufosinate ammonium herbicide (confidential information is provided in Annex 1) and the third parental line contains an insert conferring tolerance to glyphosate herbicide (confidential information in notification B/ES/01/05).

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:
The list of genetic elements inserted in the parental lines are provided in annex to the SNIF.

6. Brief description of the method used for the genetic modification:
The tested maize hybrids have been obtained by crossing three genetically modified parental lines. The description of the methods used for the genetic modification of the parental lines are provided in annex to the SNIF.

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 goal of this release is to collect data on the composition, protein expression and herbicide residues of the different parts of the modified plants as well as their non-modified counterparts.

2. Geographical location of the site:
4 sites in Zaragoza
2 sites in Huesca.

3. Size of the site (m2):
Zaragoza, 4 sites:

Location Size (m2)
Cogullada, Zaragoza 4700 m2
Juslibol, Zaragoza 10000 m2
Cogullada, Zaragoza 11000 m2
Juslibol, Zaragoza 5000 m2

Huesca, 2 sites:

Size (m2)
Gurrea de Gallego, Huesca 2900 m2
Gurrea de Gallego, Huesca 5200 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:
Field trials have already been conducted in several locations with the individual events and no environmental problems were reported for these trials. The transgenic plants resulting from the traditional crossing have appeared normal in all respects in the current trials conducted in South America. They were indistinguishable from the non-genetically modified corn plants except for showing tolerance when the herbicides (glufosinate and glyphosate) have been applied as well as showing resistance to Lepidopteran insects such as European corn borer.

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 GM maize tolerant to glyphosate nor from GM maize tolerant to glufosinate and resistant to Lepidopteran and Coleopteran insects have been reported.

Brief description of any measures taken for the management of risks:
The shedding of pollen from the GM plants will be controlled by removing the tassels or by bagging them before any pollen shed can occur. Moreover, a 200m-isolation distance will be maintained to any other commercial corn crop.

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. For this trial, a few seeds will 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 glyphosate or glufosinate 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 glyphosate or glufosinate) will be used in order to ensure destruction if needed.

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