Ginkgo biloba L. (Ginkgoaceae), known as ginkgo, is a species of gymnosperm tree native to China, but also a popular ornamental tree in Europe and North America. It is a very suitable species for cultivation in shelterbelts, multiple-purpose plantations, and urban conditions. On the territory of the Republic of Serbia, ginkgo occurs in green areas mainly as individual trees, or in smaller groups, rarely in tree rows. In the wider zone of the city of Belgrade, 94 trees are found. The analysis of several morphological traits and phenotypic characteristics of two year-old ginkgo seedlings in the test with seven half-sib lines sampled from green spaces of Belgrade was conducted in order to provide the basis for planting stock selection and the establishment of plantations adapted to urban conditions. The obtained numerical data was processed employing descriptive statistics and analysis of variance (ANOVA) with post hoc Fisher’s least significant difference (LSD) test. Compared to the other sampled trees, the progeny of a tree sampled in Zemunski Quay have superior phenotypic characteristics [number of leaves /arithmetic mean ± standard deviation/ 12.60 ± 1.55; seedling height (cm) 18.97 ± 2.57; root collar diameter (mm) 5.91 ± 0.93; mass of above-ground part (g) 1.40 ± 0.38; mass of under-ground part (g) 2.62 ± 0.80], representing a promising source of reproductive material for plant production. ANOVA and LSD show that, in most cases, there are statistically significant differences between the mean values of the analyzed characters, suggesting there is a significant variability among the analyzed genotypes.
