Abstract :Objective: The main aim of this study to determine the yield characteristics, nut and kernel defects of \'Karafındık\' hazelnut clones grown in Fatsa (Ordu) district. Materials and Methods: The plant material of the study was ‘Karafındık’ hazelnut clones grown in region. In the study, the cluster number, nuts per cluster, plant yield, yield efficiency, and yield fluctuation were determined as yield characteristics; good kernel, defective kernel, blank nut, shriveled kernel, twin kernel, abortive kernel, black tipped kernel, moldy kernel, and rotten kernel were determined as nut defects. Results: The differences between cluster number, nuts per cluster, plant yield, yield efficiency, and good kernel ratio were found to be statistically significant (p<0.05). In the clones examined, the nuts per cluster was determined 2.30 (KF-53)-3.72 (KF-48), the plant yield was determined 93 g plant-1 (KF-53)-758 g plant-1 (KF-16), the yield efficiency was determined 2.03 g cm-2 (KF-53)-26.99 g cm-2 (KF-11), the good kernel was determined %60.9 (KF-23, KF-25)-%97.4 (KF-42), the defective kernel was determined %2.6 (KF-42)-%37.4 (KF-25), and the blank nut was determined %0.0 (in 16 different clones)-%14.4 (KF-23). Conclusion: It was determined that there were fluctuations in the yield amount of the clones from year to year, while KF-16, KF-20, KF-1, and KF-49 clones had the highest plant yield.
