Fruit characteristics of native rose hip (Rosa spp.) selections from the Erzurum province of Turkey

This research was conducted in the Erzurum province of eastern Turkey during 1996–98. The rose hip (Rosa spp.) population of c. 10 000 seedling shrubs was examined with regard to fruit and shrub properties. Twelve promising rose hip genotypes were selected, six of which belonged to R. dumalis, four to R. canina, and one genotype was selected in both R. pulverulanta and R. montana. The genotypes exhibited a range of 3.149–4.803 g for fruit weight, 63.11–71.13% for fruit flesh ratio, 1074–2557 mg/100 g for ascorbic acid, 31.01–36.72% for total soluble solids, and 34.82–40.15% for total dry weight. One selection ('ERS 15') was classified as thornless. © 2004 Taylor & Francis Group, LLC.
