Pre–selection studies have been carried out in Kocaeli region in order to select superior
types from the populations of walnut trees grown from seeds. For this purpose, important
settlement units of walnut were visited and 148 fruit trees were taken in consideration of
the preliminary information given by the breeder and selection criteria. Important fruit
characteristics were examined in the plates. As a result of the research, fruit weight was
determined as 16.96–6.33 g, internal weight was 9.02–2.03 g, internal ratio was 67.41%–
29.93% and crustal thickness was 2.30–1.19 mm. Tipler was found to be in good condition
due to its full and solid ratio. 129 types were found to be 100% full and sturdy and 19 types
of empty fruit.
