Abstract
This study was carried out to determine the correlation between fruit size and picking scar diameter of organically grown northern highbush blueberry cultivars. In the experiment, eight northern highbush blueberry cultivars (Toro, Brigitta, Darrow, Patriot, Bluecrop, Bluegold, Bluejay and Chandler) (Vaccinium corymbosum L.), have five years old plants and grows in Trabzon conditions, were used. The differences in the fruit size and the picking scar diameter among the cultivars, and the annual differences within each cultivar were studied. Berry width varied between 14.22 - 20.43 mm and fruit weight varied between 1.76 - 4.22 g. While Chandler (2.86 - 3.14 mm) had the biggest scar size, Patriot and Brigitta (2.14 - 2.21 mm) had the smallest scar size. Also, it was determined that picking scar size correlates with fruit width and weight for the harvest year. However, relationship between the fruit width and the scar size of eight cultivars is significantly positive.
