Fruit properties of rose hip (Rosa spp.) genotypes selected from akkuş, ordu province

Abstract

In this study, fruit properties of 19 rose hip (Rosa spp.) genotypes selected from a large number of genotypes in the natural rose hip population in Akkus district (Ordu province) in 2014-2015 were determined. The genotypes belonged to Rosa dumalis Bechst., Rosa gallica L. and Rosa canina species. They had a range of 1.22-3.47 g in fruit weight, 10.2-16.9 mm in fruit width, 13.2-25.2 mm in fruit length, 1.25-2.09 in fruit shape index, 62-72% in fruit flesh ratio, 16-35 in seed number, 13.6-24.4% in total soluble solids, 560-1025 mg 100g-1 in C vitamin content, and 1.06-2.48 Brix° in titratable acidity. The five genotypes were less thorny plants. The two genotypes (AK-75 and AK-20) were evaluated as promising in terms of fruit weight and fruit flesh ratio. In addition, AK-63 for TSS content and AK-16 for vitamin C content were found remarkable. Findings revealed that some genotypes could be valuable as genetic material for future breeding efforts.
