The experiment was carried out in an area that had been previously cultivated with peach trees for more than 15years in the municipality of Eldorado do Sul, in the state of Rio Grande do Sul, Brazil. The Maciel and Chimarrita peach tree cultivars were grafted on 'Aldrighi', 'Capdeboscq', 'Okinawa', 'Flordaguard', 'Nemaguard', and 'Umezeiro'. The 'Umezeiro' rootstock caused high plant mortality in both scions, as well as low productivity and higher alternate bearing; it also affected the qualitative and ripening attributes of the fruits of 'Chimarrita'. The 'Aldrighi', 'Capdeboscq', 'Okinawa', 'Flordaguard', and 'Nemaguard' rootstocks induced a similar yield in both scions. The trunk cross-sectional area (TCSA) did not differ between rootstocks in 'Maciel', but in 'Chimarrita', TCSA was higher on 'Flordaguard' than on 'Umezeiro' in some seasons. Regarding the average of rootstocks, 'Maciel' showed higher TCSA, pruning mass, and average yield than 'Chimarrita', as well as changes in qualitative and ripening attributes. The Maciel cultivar shows the best productive performance in replanting areas, and the 'Capdeboscq' and 'Aldrighi' rootstocks induce satisfactory agronomic performance.  aReplant disease  aYields  aProdutividade  aPrunus Persica  aDoença de replantio  aMortalidade de planta  aPlant mortality1 aMARODIN, G.
