Özet

This study aimed to select superior rose hip genotypes among the germplasm naturally distributed in the province of Van (Muradiye and Caldiran towns) (in the Eastern Anatolia Region of Turkey) and to determine the biochemical and pomological properties of these genotypes in 2009 and 2010. In the first year of the study, 500 rose hip genotypes were marked in order to be investigated. Based on the results of chemical and pomological analysis, 20 genotypes were reexamined in the following year. Based on the results of two years of physical and chemical analyzes among the 120 rose hip genotypes, the superior genotypes were selected by a weighted ranking scale. Based on the weighted ranking scale, the 16 rose hip genotypes (M04, M11, M16, M29, M40, M54, M55, M61, M67, M72, C89, C90 C101 C106, C107, and C113) having highest scores were selected for their superior traits. Among these selected genotypes, fruit weight ranged from 2.43 to 4.88 g; fruit length varied from 21.48 to 26.27 mm; fruit width varied from 13.04 to 16.51 mm; fruit flesh percentage ranged from 49.10 to 76.20%; soluble solid content varied from 17.20 to 23.00 degrees Brix; vitamin C content ranged from 582.24 to 711.09 mg/100 g; total dry matter content varied from 45.70 to 53.26%; titratable acidy ranged from 2.04 to 3.61%; and pH varied from 3.03 to 4.15. Moreover, there were 2 thornless, 5 low-thorny and 9 thorny genotypes among the selected among the 16 rose hip genotypes.
