Twenty‐one cultivars of sour orange ( Citrus aurantium L) and relatives selected in different areas of Spain were studied. Morphological determinations were carried out both in leaves and in fruits, including leaf size and area, number of oil glands, petiole length, fruit weight, number of seeds and others. Biochemical analysis included electrophoretic separations of proteins from leaves and fruit rind as well as peroxidases and esterases from some of the organs. Also chromatographic separations of rind oils were carried out in mature fruits. Quantitative and qualitative differences were detected for some of the cultivars. Enzyme differences were found to be adequate for distinction at the specific level. Two of the cultivars, ‘Bergamot’ and ‘Amargo clementino’, segregate from the main group, which indicates their belonging to a different species or to a hybrid. The validity of the present determinations for distinction and characterisation of material to be included in a citrus germplasm bank is discussed.
