URIBE-BUSTAMANTE, Ariadna; CURTI-DIAZ, Sergio Alberto; HERNANDEZ-GUERRA, Carlos  and  TICANTE-MONTERO, Sandra Julieta. Quality of 'Valencia' orange grafted on 20 rootstocks. Rev. Chapingo Ser.Hortic [online]. 2013, vol.19, n.1, pp.61-69. ISSN 2007-4034.  https://doi.org/10.5154/r.rchsh.2011.08.043.

The objective of the present study was to determine the rootstocks among a group of 20 that confer equal or better quality to the fruit of 'Valencia' orange with respect to that achieved with sour orange. The rootstocks evaluated were Troyer, Carrizo, Swingle, Sour orange (regional control), Cleopatra, Morton, Rubidoux, Rough Lemon, C-35, Sunki, Volkameriana, Macrophylla, Amblicarpa, Yuma, Taiwanica, Pomeroy, Shekwasha, Flying Dragon, Severinia buxifolia and Sacaton. The response variables were fruit size, skin color, roughness and thickness of skin, weight of the fruit parts (juice, skin, pulp, seeds) and internal quality. There were differences among rootstocks in equatorial and polar diameter, percentage of skin color of the fruit rind and weight of the fruit, seeds and skin, as well as degrees Brix, soluble solids and acidity. The rootstocks that matched the quality of fruit produced with Sour orange were: Flying Dragon, Cleopatra, Sacaton, Yuma, Morton, Rubidoux and Troyer.
