Brazilian researchers have developed a methodology using drones equipped with RGB cameras to speed up and reduce the cost of selecting genetically modified corn plants. The method involves drones flying over plantations weekly, capturing images that are converted into indexes to assess plant health. This allows for the identification of promising varieties and their performance to be simulated in different environmental conditions. The method was tested in 2023 with 21 corn varieties and showed reliable results, reducing operating costs and allowing studies to be conducted in smaller areas. The data collected was used to develop predictive models to facilitate the selection of varieties adapted to different environmental conditions.
