Loquat (Eriobotrya japonica L.) grown well for commercial purposes in subtropical regions nearly 30 countries and originated from China. The most important loquat producers in the world are China, Spain, Turkey, Pakistan, India, Italy and Brazil. In this study, ten pre-selected promising loquat genotypes sampled from eastern Black region and analyzed for their important morphological, biochemical and antioxidant characteristics. The standard cultivar ‘Sayda’ is also included in the study. The results indicated differences for all of the morphological, biochemical and antioxidant characteristics among tested genotypes. Fruit mass and fruit flesh percentage of the genotypes ranged from 35.40 g (LOQ-8) to 46.90 g (LOQ-5) and from 79.40 (%) to 86.32 (%) indicating some local genotypes had higher fruit mass and fruit flesh percentage than standard cultivar ‘Sayda’. Total phenolic content was the highest as 263 μg GAE/g in LOQ-7 genotype while the lowest in LOQ-8 genotype (185 μg GAE/g). LOQ-7 genotype had the highest total antioxidant capacity. Local genotypes in general have higher total phenolic, total carotenoid, vitamin C and antioxidant activity than cv. ‘Sayda’.

A rose hip is the fruit of a rose plant and mostly belongs to Rosa canina and Rosa dumalis. These species are genuine found as wild in natural conditions, while in some countries are cultivated for their hips that are picked and used in a wide variety of preparations. Because they contain a variety of antioxidants, carotenoids, flavonoids, polyphenols, leucoanthocyanins and catechins, rose hips are considered to be a good cancer preventative. The Rosa genus has been the focus of many recent studies due to its potential benefic effects on treatment and prevention of several diseases. However, there are few in vitro studies concerning its composition and antioxidant capacity. The aim of the present study was to determine bioactive content, including ascorbic acid, total phenolics, total flavonoids, total carotenoids and antioxidant activity of Rosa dumalis genotypes growing wild in Erzurum province located eastern Anatolia. The results revealed that fruits of Rosa dumalis different genotypes were rich rich in terms of vitamin C, which ranged from 402 to 511 mg/100 g fresh weight base. The total phenolic content varied from 297 to 403 mg/100 g fresh weight. The genotype 'E-09' had the highest total flavonoids content (229 mg quercetin equivalent/100 g fresh weight) and the lowest value was attributed to genotype 'E-04' with 143 mg/ quercetin equivalent/100 g fresh weight. The antioxidant activity of the genotypes was between 12.9-28.6 μg Trolox/ml samples. The results revealed that there was enough diversity among Rosa dumalis genotypes for bioactive content and promising genotypes, with high bioactive content, were determined, which can become study material for future breeding activities.
