Results of early evaluating the compatibility between citrus (Citrus sp.) scions Truc (C. hytrix), Carrizo (C. sinensis Osb.x P. trifoliata L .Raf.) rootstocks under the trial field located at Tri Ton-An Ciang in the year 4th after planting, revealed that the grafted trees of seedless Mat orange (C. sinensis L. Osbeck, Sanh orange (C. nobilis Lour.) and Da xanh pumelo (C. maxima (Burm.). Merr.) grafted onto Truc rootstock were the better vigorous growth based on tree height, canopy volume, trunk diameter and the ratio of sion and rootstock diameter as compared to that grafted on Carrizo rootstock. The higher fruit number was obtained from the combinations of the seedless Mat orange grafted onto Truc was the highest fruit number (47.33 fruits/tree) and followed by Sanh orange grafted onto Truc (16.67 fruits/tree). The fruits of seedless Mat orange were the thinner fruit peel, the seedy fruit (0.67 seeds/fruit) and the lower total soluble solid content and flavor of juice; meanwhile. Sanh orange grafted on truc gave the better fruits with the larger size, the higher total soluble solid content, the better fruit juice color and flavor as compared to the specific variety characteristics.
