Includes references.

The present study was carried out during seasons of 2001 and 2002, to evaluate Valencia orange (c. Sinensis L. Osbeck) trees budded on four citrus rootstocks, i.e. Cleopatra mandarin (C.M.), Sour orange (S.O.), Rangpur lime (R.L.) and Volkamer lemon (V.L.). The experimental trees were grown in a newly reclaimed sandy soil at the orchard of EL-Kassasin Horticulture Research Station, Ismaila Governorate Egypt. The evaluation program considered the major characteristics of vegetative growth, scion projection area, root spread area and their ratio, yield and fruit quality. The considered parameters were mostly of significant responses among Valencia orange cv. and the four studied rootstocks. The study proved the superiority of Volkamer lemon rootstock for Valancia orange trees, as compared with the other tested rootstocks. On the contrary, Rangpur lime rootstock seemed to be the worst one for Valencia orange trees under the experimental conditions.
