Özet:
Hazelnut (Corylus avellana L.) is a critical commodity for Turkey due to its economic and nutritional value. Turkey ranks first in world hazelnut production with 65- 75% of the market. Due to the signifacance of this crop, it is crucial to preserve Turkish hazelnut genetic diversity. In the current study, a panel representing the entire national collection of 430 accessions was used. Genetic characterization of the panel revealed 7609 high-quality SNPs, 5567 of which were physically mapped to the Tombul reference genome. Fingerprint analysis indicated that all individuals could be distinguished with only seven SNP markers. Population structure analysis of the dataset indicated that the panel’s genetic relationships were explained by three clusters containing 8, 17, and 25 accessions, respectively. Nearly half of the accessions had admixed ancestry. The admixed material contained 8 cultivars, 22 landraces, and 12 wild accessions indicating that nearly 50% of each type of material had admixed ancestry. An unweighted neighborjoining dendrogram was constructed using a distance matrix computed with the identity by state distance measure. The calculated dissimilarity values ranged from 0.15 to 0.30 with a mean of 0.26. This study is the first time that the Gras-Di sequencing approach was used on a nut tree and provides a new perspective on hazelnut genetics. In addition, the panel will serve as a well-characterized genetic resource for future work on this economically important tree nut crop.
