Resumo


Genetically modified plants have high potential for use and benefits; they are dynamic and tend to enable more sustainable agricultural management alternatives as scientific and technical information are applied. However, little is known about the effects of genetic modifications to induce resistance to herbicides and insect attacks on agronomic characteristics of maize plants. The objective of this study was to evaluate the effects of transgenic events on morphological and productive characteristics of maize hybrids. A field experiment was conducted in two crop seasons, using conventional and transgenic isogenic hybrids. The variables analyzed were plant height, ear height, stem diameter, and grain yield. The genetic modifications used in the evaluated transgenic hybrids affected the morphological and productive characteristics of the maize plants. The transgenic hybrids presented 5% higher plant height and 10% higher grain yield than the conventional hybrids.
