2. Description of the traits and characteristics which have been introduced or modified, including marker genes and previous modifications:
This notification is for the evaluation of a hybrid line obtained through sexual crossing of one transgenic line, which is resistant to some lepidopteran insect pests (information provided in: C/ES/01/01 Maize Line 1507)), with another transgenic line, which is tolerant to herbicides (information provided in: C/ES/00/01 Maize Line NK603).

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:
The list of the inserted genetic elements in both parental lines was provided in the notifications: C/ES/01/01 and C/ES/00/01.

6. Brief description of the method used for the genetic modification:
The method of genetic modification used to generate the transgenic parental lines was provided in the notifications: C/ES/01/01 and C/ES/00/01.

7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:
Not relevant.

Experimental Release

1. Purpose of the release:
The purpose of the release is to determine the composition of the hybrid line along with the expression levels of the inserted transgenes in different plant tissues through out the growing season.

2. Geographical location of the site:
The releases will take place at six different locations of the provinces of Zaragoza and Huesca.

3. Size of the site (m2):
Location Area (m2) including all varieties and border lines
Montana Zaragoza 1500
Cogullada 1500


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:
During the field trials performed with the parental lines, no particular characteristics that could have a negative impact on the environment or human health were observed. Moreover, no significant differences between the parental lines and the conventional maize plants were detected.

Environmental Impact and Risk Management

Summary of the potential environmental impact from the release of the GMPts:
No maize sexual compatible species have been found in Spain. Maize has a long history of safe use and been extensively domesticated by humans. The genes introduced into one of the parental lines have a very specific mode of action, conferring resistance to some lepidopteran insect pests and tolerance to glufosinate whereas in the other parental line, a gene which confers tolerance to a plant herbicide, has been introduced. This is based on information provided on the dossiers: C/ES/01/01 and C/ES/00/01.

Brief description of any measures taken for the management of risks:
The trials are going to be isolated from any other maize plot by a minimum distance of 200 m or the anthers will be either castrated or bagged to prevent pollen flow. In addition, a non-GMO maize 4 row border will be planted and subsequently destroyed at the end of the experiment. In addition, 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.
Strict biosafety practices will be implemented according to the Competent Authority guidelines. The following year a different crop will be planted in these lots to facilitate the detection and destruction of any volunteer plant. All the plant products from these trials will be manually or chemically destroyed, by application of a non-selective herbicide other than glyphosate or glufosinate,. Trained people will carry on the experiment and follow up closely. Regular monitoring visits will be implemented during the growing season to evaluate the performance and looking for any unintended effects and in the following season to control volunteers.


Summary of foreseen field trial studies focused to gain new data on environmental and human health impact from the release:
The field trials are meant to assess the composition and expression of the hybrid line under evaluation.
According to the results obtained in the trials, the commercial strategy will be drawn.
