Resumo: Abstract: The objective of this study was to evaluate the adaptability and stability of conventional (55 to 65% linoleic acid) and high (greater than 80%) oleic acid sunflower genotypes cultivated in Central Brazil. Grain and oil yield of genotypes were evaluated from 2006 to 2009 under randomly block designs in various locations of the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Rondônia, São Paulo, and Distrito Federal. Genotypes? adaptability and stability were evaluated by the partition of the general mean into means from favourable or unfavourable environments, by the regression coefficients and deviations and the coefficient of determination. The hybrid NTO 3.0 (high oleic genotype) were the only genotype that had superiority in favorable and unfavorable environments, for both traits. Furthermore, this genotype had high stability, high responsiveness to environmental improvement for grain yield and average responsiveness to oil yield.
