3. Is the same GMPt release planned elsewhere in the Community?NoHas the same GMPt been notified elsewhere by the same notifier?NoGenetically modified plantComplete name of the recipient or parental plant(s)
2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:The genetically modified 1507x59122 maize varieties that will be tested in these field trials are resistant to certain Lepidopteran insects, such as the European corn borer (Ostrinia nubilalis) and to certain Coleopteran insects, such as the Western corn rootworm (Diabrotica virgifera virgifera), and tolerant to glufosinate-ammonium herbicide. This maize was derived through traditional breeding methods between progeny of genetically modified 1507 maize, which is resistant to certain lepidopteran insects and tolerant to glufosinate herbicide, and 59122 maize, which is resistant to certain coleopteran insects and tolerant to glufosinate herbicide.Genetic modification3. 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:The genes introduced in 1507x59122 maize are the cry1F gene from Bacillus thuringiensis var. aizawai, providing resistance to certain Lepidopteran insects and the pat gene from Streptomyces viridochromogenes, introduced as a selectable marker, providing tolerance to glufosinate-ammonium herbicide, like in 1507 maize, and the cry34Ab1 and cry35Ab1 genes from Bacillus thuringiensis strain PS149B1, providing resistance to certain Coleopteran insects and the pat gene from Streptomyces viridochromogenes, introduced as a selectable marker, providing tolerance to glufosinate herbicide, like 59122 maize, along with their regulatory components necessary for expression in maize plant:

- the cry1F gene, the UBIZM1(2) promoter, the ORF25PolyA terminator.
- the pat gene, the CaMV35S promoter, the CaMV35S terminator.
- the cry34Ab1 gene, the UBIZM1(2) promoter, the PINII terminator.
- the cry35Ab1 gene, the Peroxidase promoter, the PINII terminator.
- the pat gene, the CaMV35S promoter, the CaMV35S terminator.6. Brief description of the method used for the genetic modification:No genetic modification was made on the 1507x59122 maize directly: it was derived through traditional breeding methods between progeny of the genetically modified 1507 and 59122 maize.
1507 maize was genetically modified using a particle acceleration method, 59122 maize was genetically modified using Agrobacterium transformation 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 Release1. Purpose of the release:Several types of trials are planned, to collect various 1507x59122 maize tissue samples for protein expression analysis, and to evaluate the impact of the cultivation of transgenic maize varieties on key non-target arthropod populations.2. Geographical location of the site:The release is planned at the following locations in Spain in 2006:
- Aragón: Zuera (Zaragoza), Gurrea de Gállego (Huesca).
- Castilla-La Mancha: Tarazona de la Mancha (Albacete), Alpera (Albacete), Membrilla (Ciudad Real).
- Cataluña: Alpicat (Lleida), Alguaire (Lleida).
- Madrid: San Martín de la Vega (Madrid).
- Navarra: Cortes (Navarra).3. Size of the site (m2):In 2006, each site could have up to 100 m² sown with the genetically modified maize subject of this notification (1507x59122 maize), the total trial surface (all varieties and borders included) being larger at each site. In 2006, the site in Alguaire (Cataluña) could have up to 4000m² sown with 1507x59122 maize, as the trial to evaluate the impact on key non-target arthropod populations will be carried out in collaboration with the University of Lérida. The total trial surface (all varieties and borders included) will be larger.
In the following years, there could have up to ten sites and up to 5000 m² of 1507x59122 maize 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 different locations across maize growing regions in North America, South America and Europe, and no environmental problems were reported for these trials. The transgenic maize plants were indistinguishable from the non-genetically modified maize plants except for showing resistance to certain Lepidopteran insects, such as European corn borer, and to certain Coleopteran insects, such as Western corn rootworm, and showing tolerance when glufosinate herbicide was applied, traits due to the genetic modifications.Environmental Impact and Risk ManagementSummary 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 Lepidopteran and Coleopteran insects and tolerant to glufosinate herbicide 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 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. No plant or plant product coming from the trials will enter the food or feed chains.
Volunteer maize will be monitored during the following year. An herbicide treatment (other than glufosinate) 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.Final reportEuropean Commission administrative informationConsent given by the Member State Competent Authority:Yes23/03/2006 00:00:00Remarks:There are several Autonomous Communities as competent authorities for give the consent of these field trials:
