AB  - Genetically conditioned variation in pollen has been demonstrated to have a substantial influence on reproductive mechanisms and population dynamics. The present study evaluated the genetic variability of 28 pollen samples of Corylus avellana L. using iPBS (Inter Primer Binding Sites Polymorphism) markers 1882 and 2152. The collection of biological material was undertaken at various locations across five European countries, with the objective of capturing a broad spectrum of environmental conditions. The genetic relationships among the samples were evaluated by constructing a dendrogram using the UPGMA (Unweighted Pair Group Method with Arithmetic mean) with genetic similarity estimated based on the Jaccard coefficient. Clustering analysis of the 1882 iPBS marker identified four major clusters. Similarly, applying this analysis to the 2152 iPBS marker identified six major clusters. The average Jaccard genetic similarity coefficient was 0.415 and 0.608 for iPBS markers 1882 and 2152, respectively. With regard to the iPBS marker 1882, the highest degree of genetic similarity, indicated by a Jaccard coefficient of 0.73, was observed between the Ukrainian sample from Kyiv park and the sample from Germany, Darmstadt. The iPBS marker 2152 revealed that the Slovak sample originating from the field near Ivanka pri Nitre and the Ukrainian sample from Kyiv park shared the highest genetic resemblance, with a Jaccard coefficient of 0.815. The results obtained demonstrate a high degree of genetic diversity among retrotransposon insertions in hazelnut pollen. Furthermore, the iPBS technique has been shown to be reliable for assessing genomic variability in Corylus avellana L.
