Clonal selection in Mincane hazelnut (Coryllus avellana L.) cultivar in Akçakoca district of Düzce Province.

Türkiye has dominated world hazelnut production for a long time and one of the most important hazelnut growing areas in the Black Sea region is Düzce province. Agriculture plays an important role in Düzce economy and hazelnut orchards occupy 45% of total agricultural areas. Mincane hazelnut cultivar widely grown in Akçakoca and shows variability particularly for nut characteristics. Thus, this study was aimed to select promising clones with superior features from the population of the Mincane hazelnut cultivar. In the selection study, some important nut characteristics were examined. According to a modified weighted ranking method results, 7 Mincane hazelnut clones were selected as promising. In the selected clones, nut weights varied between 1.85 g (81AKC21)-2.12 g (81AKC11), kernel weight 0.90 g (81AKC15)-1.08 g (81AKC05), kernel ratio 46.66% (81AKC11) -56.09% (81AKC21), shell thickness 1.10 mm (81AKC05)-1.17 mm (81AKC17 and 81AKC15), nut size 15.72 mm (81AKC15)-17.21 mm (81AKC10), kernel size 11.23 mm (81AKC15)-12.43 mm (81AKC10) and kernel shape index 1.08 (81AKC19)-1.22 (81AKC21), respectively. In the selected clones, the number of fruits per cluster was found to be between 1.85 (81AKC21)-4.85 (81AKC17) and clones 81AKC11 and 81AKC15 gave 100% intact kernel. [ABSTRACT FROM AUTHOR]
