%X the use of an appropriate rootstock depends on the knowledge of its affinity with the cultivar scion as well as its influence on liveliness and productiveness. the purpose of this research was to evaluate the vegetative and -productive development, and fruit quality of the cv. study was to evaluate the vegetative growth, fruit production and quality of cv. 'maciel' grafted on different peach rootstocks. the cultivars used as rootstocks were seeds from industry, 'capdeboscq', 'aldrighi', 'tsukuba 1', 'a clone of okinawa', 'okinawa clone 12', and 'rubira' 'nemaguard' and as canopy it was used cv 'maciel'. it was measured trunk diameter, canopy volume, amount of chlorophyll, pruning intensity, productivity, mass, and color of pulp fruit firmness, tss, ta and tss/ta ratio. the experimental design was randomized blocks with eight levels for the factor rootstock, each consisting of three replications with five plants per replicate. it was observed in the last assessment in 2008, the difference in diameter of the trunk between the rootstocks, especially 'industria' (47.2mm) and 'tsukuba' (46.8mm). in the canopy volume the highlight among the rootstocks occurred with 'industria' (1,60m3) and 'nemaguard' (1,63m3). the amount of chlorophyll was similar with 'nemaguard', 'tsukuba 1', 'okinawa clone 1', 'rubira' and 'ind¨²stria'. fruit weight was greater with 'rubira' (143g) and 'tsukuba' (135g) in 2007 and in 2008 and in 2008 most 'okinawa clone 12' (73g), 'capdeboscq' (83g), 'aldrighi' (81g) and 'nemaguard' (82g). there was variation in productivity in production cycles, the highlight occurred in 2007 with 'tsukuba 1' (0.32ton ha-1) and in 2008 with 'industry' (8.6tons ha-1). with the 'okinawa clone 12' it was observed higher firmness (12.1 and 11.8 pounds in 2007 and 2008, respectively). highest tss / att stood out with 'tsukuba 1' (18.3). based on the differential responses it was concluded that the vegetative growth and fruit quality of cv. 'maciel' are affected by the root
