The objective of the study was to evaluate the physical-chemical characteristics of six peach cultivars over the Okinawa and Umê rootstocks. The experiment was carried out at Polo Regional Alta Sorocabana-APTA, in Presidente Prudente, SP. The parameters evaluated were fruit mass,length, sutural diameter, yield per plant, soluble solids content and titratable acidity. The evaluations allowed to conclude that the rootstocks affected the mass of fruits, and Umê showed bigger average mass. In 2006, the results showed a significative increment of yield in all cultivars, and Doçura 2 cultivar when compared to Umê showed values above the average. Doçura 2 cultivar when compared to Okinawa root-stock was distinguished by congregating better fruit physical characteristics and yield per plant. Talismã and Dourado 2 cultivars showed fruits with bigger mass, length and sutural diameter of fruits.Tropical cultivar was distinguished by better quality characteristics, without depending on the root-stock.
