Abstract
This study was carried out during 2008-2011 years in order to determine genetic population of Service tree genotypes naturally grown in Tokat region, and also, to select genotypes from the resources in terms of selection criteria, adopted for the study.
During the surveys, 304 genotypes out of 2275 genotypes recorded in the region were pre-selected for further detailed characterization.
According to detailed characterization, 10 genotypes were selected as candidate for cultivars.
Among the 10 candidate genotypes; two genotypes were very weak, four genotypes were weak, one genotype was medium growth and three genotypes were strong growth.
All candidate genotypes showed periodicity and the yields of all candidates categorized as high.
According to years and genotypes, the average fruit weights were in the range of 9.69-36.28 g and the total amount of dry matter also ranged from 30.10 to 41.48%. Soluble solid content was ranged from 17.65 to 35.40% at maturation period, and from 18.05 to 29.70% at ripenning period according to the years and genotypes.
While total phenolic contents in fruits were in the range of 105.10-206.85 mg 100 g‑1 at maturation period, those ranged from 84.08 to 137.51 mg 100 g‑1, respectively.
