Oriental spruce (Picea orientalis L. LINK) is one of the most considering species distributed along Colchis sector of Euro-Siberian geophytological region the world. The tree taxon is mostly used in reforestation in the Northeast Black Sea Region of Turkey. However, a few data is available about its intra-specific variation and adaptability. To study the pattern of natural variation of Oriental spruce, 25 populations taken from natural stands in Turkey were compared based on phenotypic variation of cone, seed and wing morphology, and two geographic parameters (altitude and watershed). ANOVA showed that the morphological characters differed in the populations. Also, the cluster modelling performed on morphological characters suggested that geographic parameters (watershed and altitude) exhibited different groups.
