Corylus avellana L. stands as one of the world's most coveted nuts, thriving in the wild within the Fandoguloo forests of Iran's Ardabil province and showcasing remarkable diversity in this region. To assess the distribution of genetic diversity within and between populations, 78 genotypes from various regions of Iran, including Ardabil, Arasbaran, and Miyaneh, underwent analysis using Start Codon Targeted (SCoT) polymorphism. Additionally, the phytochemical characteristics of Corylus avellana L., such as ash, taxol, total phenol, palmitic acid, fiber, palmitoleic acid, carbohydrate, stearic acid, flavonoid, oleic acid, linoleic acid, fat, antioxidant compounds, and total phenol, were examined. The results revealed that 15 SCoT primers amplified 165 polymorphic polymerase chain reaction fragments, with the SC3 and SC21 primers exhibiting the highest and lowest polymorphic information content, respectively. The calculated marker index for the primers ranged from 2.6 to 6.1. The Ardabil population boasted the highest allele frequency, with a 100% polymorphism rate across all studied primers. The primers SC21, SC20, and SC5 showed the highest polymorphic rates among the populations with 14 fragments. The gene flow within populations was 0.4, whereas the gene flow between populations was 0.7, and the fixation index (Fst) was 0.4. This research underscores the effectiveness of the SCoT marker in gauging the genetic diversity of C. avellana, making it a promising foundation for future research on the population and evolutionary genetics of this economically significant species.
