General informationNotification NumberB/HU/05/02/2Member State to which the notification was sentHungaryDate of acknowledgement from the Member State Competent Authority17/02/2005Title of the ProjectField trials program of maize varieties resistant to certain Coleopteran insects and tolerant to a herbicide (59122 maize)Proposed period of release:01/04/2005 to 31/12/2008Name of the Institute(s) or Company(ies)Pioneer Hi-Bred Hungary Ltd., ;
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:New genes were introduced into the genetically modified 59122 maize plants so that they can fight against the damages caused by certain Coleopteran insect pests, such as Western corn rootworm (Diabrotica virgifera virgifera), and tolerate application of glufosinate-ammonium herbicide for the weeding of maize crop.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 59122 maize are the cry34Ab1 and cry35Ab1 genes from Bacillus thuringiensis strain PS149B1, providing resistance to certain Coleopteran insects and the pat gene from Streptomyces viridochromogenes providing tolerance to glufosinate herbicide, together with only their regulatory components necessary for expression in maize plant.6. Brief description of the method used for the genetic modification:The genetic modification was carried out by using Agrobacterium transformation method in order to introduce the DNA insert into the maize genome. The T-DNA on the Ti plasmid has been replaced by the construction containing the 3 genes along with the regulatory components necessary for expression.7. If the recipient or parental plant is a forest tree species, describe ways and extent of dissemination and specific factors affecting dissemination:Not applicableExperimental Release1. Purpose of the release:Several types of trials will be carried out, such as trials for protein expression analyses, effects on non-target organisms, collecting data on agronomic value and insect resistance, and other trials in view of registration on the National List of Hungary.2. Geographical location of the site:In 2005, the location of the release sites will be as follows:

Sóskút, Sóskút Fruct Gyümölcstermelő Kft, hrsz. 01063. Size of the site (m2):Each trial site in 2005 will have up to 4000 m2 sown with the genetically modified plants, the total surface area taken up by the trials (all varieties and borders included) being higher. There will be up to 3 sites of release in 2005. In the following years, up to 6 field trials could be sown, each with up to 10000 m2 of the genetically modified plants.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:Many field trials have already been conducted at several locations since 2001 and no environmental problems were reported for these trials. The transgenic plants behaved as conventional maize. They 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 has been applied, traits due to the genetic modification.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 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.
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:Trials for effects on Non-Target Organisms:
The purpose of the release is to evaluate the impact of the cultivation of insect-resistant 59122 maize hybrids on key non-target arthropod populations, in comparison with the cultivation of non-transgenic equivalent maize hybrids treated with chemical insecticide and untreated.Final report-European Commission administrative informationConsent given by the Member State Competent Authority:Not known
