The aim of the current work was to compare five Valencia sweet oranges selection with industrial potential and in nature consumption with the varieties 'Natal'and 'Valencia' on two rootstocks: 'Swingle' (experiment I) and 'Sunki' (experiment II) when it comes as yield and with technological index. Two experiments were set up on February 2001, in Bebedouro city, São Paulo state, Brazil. The spacements were 7.0 m between rows with 5.0 m between trees and 7.0 m between rows with 3.0 m between trees, respectively for experiment I and experiment II. The experimental design used was randomized blocks, with four replications and two trees per plot. The crown varieties tested were 1) 'Natal', 2) 'Valência', 3) 'Valência Don João', 4) 'Valência late Burjasot' IVIA 35-2, 5) 'Valência Rohde Red' SRA-36, 6) 'Valência Temprana' IVIA-25, 7) 'Valência Campbell'. The varieties of Valência studied proved some similarity for yield and technological index. The 'Valência Late' can be highlighted because it was the one that resembled to the traditional Valência and Natal varieties.
