Abstract: Performed in 1995 and 1996, the aim of this research was the selection of hazelnut types grown in Terme, Çarşamba, Salıpazarı and Ayvacık districts of Samsun province. In total, 104 types were investigated. The types which resulted in 800 or more Total Weight-Ranked Points were considered. 19 types in 1995 and 22 types in 1996, five of which were preselected in 1995, were evaluated. The results were exposed to the "Weight-Ranked Method". According to the evaluation results the types 55-Ç-5, 55-T-15, 55-Ç-4, 55-A-3 and 55-Ç-7 were selected in 1995. In 1996, the types 55-S-15, 55-T-39, 55-Ç-26 and 55-Ç-8 alongside the types 55-T-15 and 55-Ç-4 of 1995 were found to be promising. 55-T-15 gave the highest nut weight (2.57 g.), kernel weight (1.34 g), nut size (19.51 mm) and kernel size (14.51 mm). The highest kernel ratio (57.20%) and good kernel ratio (96%) were observed from 55-Ç-7. 55-T-15 and 55-Ç-4 types gave the thinnest shell thickness (0.88 mm) and the highest pellicle removal ratio (100%) was determined from 55-Ç-26 hazelnut type. 55- Ç-5, 55-A-3 and 55-Ç-7, and 55-S-15, 55-Ç-26 and 55-Ç-4 types gave the lowest double kernel ratio (0%), in 1995 and 1996, respectively. The least perisperm separation was taken from 55-Ç-5, 55-T-15, 55-Ç-4 and 55-A-3 types. 55-T-39 and 55-Ç-26 resulted in the highest taste points (7.9). The total weight-ranked points were highest for 55-Ç-5 (883) and 55-S-15 (890) in 1995 and 1996, respectively.
