Variability of Scots pine (Pinus sylvestris L.) cone morphometric characters were analysed for seven populations in Serbia. 98 trees were selected in the field and the cones were collected. The sample consisted of 20 cones from each tree, and included almost 6000 measurements of cone length, cone diameter and seed number. The statistical analysis was performed using software Statistika. The study results showed significant differences in the values of the analysed characters for each individual population. We determined the interdependence (correlation) of the analysed characters and not also the direct character interaction (regression). Also, different degrees of homogeneity were determined for each analysed character within the populations. Cluster analysis was made for all three characters together, and individually for each character. The analysed biological similarity or distance regarding these three characters showed a significant population differentiation. By presenting the preliminary knowledge on the genetic variability of the study populations, the reported results will contribute to better understanding of the correlation of the analysed characters and to underlining the significance of the study characters in the population differentiation.
