In this study, the effects of local sour orange (Citrus aurantium), ‘Taiwanica’ (Citrus taiwanica), ‘Yuzu’ (Citrus
junos), ‘Troyer’ and ‘Carrizo’ citranges (Citrus sinensis x Poncirus trifoliata), ‘Cleopatra’ mandarin (Citrus reshni)
and also Citrus ampullacea, ‘Kinkôji’ (Citrus obovoidea) and ‘Sanbôkan’ (Citrus sulcata) on some pomological
characteristics of ‘Star Ruby’ grapefruit were evaluated under Adana ecological conditions. Fruit yield (kg), fruit
weight (g), height (mm), diameter (mm), index, juice quantity (%), rind thickness (mm), total soluble solids (TSS,
%), total acid content (TA, %), TSS/TA ratio, fruit peel and juice colour (hueo) were evaluated. Yield was the highest
on C. sulcata followed by that on ‘Cleopatra’ and sour orange. The largest fruit size was obtained from the trees
on ‘Carrizo’ citrange, followed by ‘Troyer’. The thickest fruit rind was showed by fruits from the trees on ‘Carrizo’
and the thinnest on ‘Taiwanica’ and sour orange. However, trees on the other rootstocks produced similar rind
thickness and did not showed significant difference from each other. There were significant differences between
rootstocks as regards TSS/TA ratio. It was the highest for fruits from the trees on ‘Carrizo’. According to the hueo
data, red colour in both peel and juice were the highest in the fruits on ‘Carrizo’ and ‘Troyer’ citranges.
