Corn strain GA21 is a genetically modified maize expressing glyphosate tolerance. The trait was produced by the microbullet bombardment transformation method with wild maize as the source of the mepsps gene. Especially in the Philippines, maize is an important crop used by about 20 percent of the population for food and feed. It is the second most important food crop after rice and the main source of income for a third of farmers. It is also the primary source of feed for the country's poultry and livestock industry. In this country, the GA21 maize strain has not changed the current production, consumption and use patterns of maize.

GA21 maize tolerates glyphosate herbicide application. The adoption of genetically modified maize essentially results in lower production costs.
In our country, no negative results were obtained regarding the gene stability for the molecular characterization of the transferred gene in obtaining GA21 maize variety.
As a result, in the light of the available information, it has been accepted that the GA21 maize type as a food material or the foods containing or produced from GA21 maize do not pose more risks in terms of human, animal and environmental health than conventional maize types.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests carried out in this context, GA21 corn type determination and quantity analysis services are also available.
