Özet

Clonal selection was practiced in three hazelnut cultivars, 'Palaz', 'Kalinkara' and 'Cakildak', collected in the villages of Ordu province over the past three years (1997-1999). The aim of this study was to select the highest quality types in each of these hazelnut cultivars. Based on an initial assessment of a total of 325 types, we selected five types from 'Palaz', three types from 'Kalinkara' and three types from 'Cakildak' to study in more detail. The best types were selection numbers (S.N.) 528 in 'Palaz', 246 in 'Kalinkara' and 229 in 'Cakildak'. The average values for these three selections were, respectively, 3.82, 4.39 and 3.50 for number of nuts per cluster; 18.49 mm, 19.49 mm and 17.81 mm for nut size; 2.40 g, 2.95 g and 1.65 g for nut weight; 55.25 %, 53.74 % and 53.48 % for kernel percentage; 1.04 mm, 1.14 mm and 0.88 mm for shell thickness; 90.75 %, 91.03 % and 80.75 % for percentage filled nuts; and 3.25 mm, 2.93 mm and 1.12 mm for kernel cavity size. In the selected types, the highest kernel percentage was 55.50% ('Palaz' S.N. 551), the highest fatty acid content was 69.07% ('Palaz' S.N. 528), the highest percentage of pellicle removal was 99.50% ('Palaz' S.N. 551); the heaviest nut was 3.17 g ('Kalinkara' S.N. 394), and the smallest kernel cavity was 0.43 mm ('Cakildak' S.N. 229).
