Brazil southern region is characterized by wide range of climatic and soil conditions. Cultivars performance varies, usually with the environments, so that a genotype is rarely the best under all  cultivation conditions. The aim was to evaluate the maize genotypes adaptability and stability in Southern Brazil. The experiment was conducted in 2008/2009 crop season, 24 mayze hybrids were evaluated in seven Municipal Districts in the states of Paraná (PR), Santa Catarina (SC) and Rio Grande do Sul (RS). Experiment was a randomized block design with three replications. Each plot consisted of two crop lines of 5 m. Evaluated parameters were constituted by final stand, humidity and grain yield adjusted to 13% moisture. Hybrids 9, 17, 3, 2, 10 and 20 showed high adaptability and stability. Adaptability of hybrid 11 was best  in the environment of Capinzal, SC.
