“…Therefore, it has been reported that phenolic and organic acids and aroma compounds, which are acidic and exhibit antioxidant activity, are present at lower levels in varieties showing high pH (Mertoğlu and Evrenosoğlu, 2019). Vitamin C and antioxidant activity characteristics, which were determined as 1.49 mg.100ml-1 and 43.88%, were found to be lower than reported in the literature (Kevers et al, 2011;Öztürk et al, 2015;Erbil et al, 2018).…”

Objective: In this research, evaluations of F1 fall pear hybrids, that obtained from different cross combinations, were made to contribute to our country' s agriculture and gene pool.Material and Methods: 11 hybrids investigated in this research were obtained from the cross combinations that 'Magness' , 'Kiefer' , 'Williams' and 'Santa Maria' cultivars were maternal and, 'Güz' , 'Santa Maria' and 'Kiefer' cultivars were used as pollinator parents. Susceptibilities of those hybrids to fire blight disease, pomological and biochemical characteristics were determinated. Besides, sensory parameters were added to the data attained by the measurements, and promising hybrids were detected through the modified weighted ranking method.Results: Fruit width, fruit length, shape index, fruit weight, fruit firmness, soluble solid content, pH, titratable acidity, vitamin C and antioxidant activity characteristics were varied between 53.22 -84.25 mm, 52.91 -105.01 mm, 0.95 -1.62, 86.51 -317.70 g, 3.32 -8.41 kg/cm2, %8.77 -16.53, 3.52 -4.73, %0.14 -0.59, 0.53 -3.17 mg.L-1 and %26.43 -%75.09, respectively. Eight hybrids were evaluated as promising fall cultivars through the modified weighted ranking method.Conclusions: Due to the lack of a definite solution against fire blight, the chemicals used are harmful to human health and organic cultivation is becoming more widespread, the pears with high fruit quality parameters and disease resistant hybrids will come to the fore in the near future, it is thought that the hybrids (2-12-43, 2-15-93, 2-12-47, 1-17-20, 3-36-87, 2-33-32, 2-15-33 and 1-16-130) transferred to the forward observation plot will contribute to pear cultivation by registering in the following period. ÖZAmaç: Bu çalışmada, farklı melezleme kombinasyonları sonucu elde edilen güzlük F1 armut melezlerinin, ülke tarımına ve genetik havuza katkı sağlaması amaçları doğrultusunda, değerlendirmeleri yapılmıştır.

“…Ozturk et al [30] reported a TP amount in the cultivars “Santa Maria” (43.8 mg/100 g) and “Deveci” (39.3 mg/100 g). Emerging evidence [31] suggests that phytochemical pear extracts are able to exhibit different levels of antimicrobial, antioxidant, and antimutagenic activities. In a systematic review on pear consumption and health outcomes, Reiland H and Slavin J [8] highlighted its healing properties.…”

In order to evaluate and identify the antioxidant properties and the phytochemical characteristics, as well as the role of the genetic background and the different fruit parts in the definition of fruit quality, we characterized the existing germplasm through nuclear simple sequence repeats (SSRs) and evaluated the genetic divergence between ancient S. Giovanni varieties (Pyrus communis L.) and different types of grafting in relation to some variables of fruit quality. On the peel and pulp of pear varieties, the contents of flavanols, flavonols, and hydroxycinnamic acids as well as total antioxidant capacity were assessed. Their role in plant defences was confirmed by a significantly higher amount in the peel (206.66±44.27, 48.45±13.65, and 31.11±11.94 mg/100 g, respectively) of S. Giovanni pears than in the pulp (71.45±34.94, 1.62±0.83, and 17.05±5.04 mg/100 g, respectively). Data obtained using capillary analysis of SSR indicate unequivocally that the four samples of San Giovanni varieties can be divided into 3 different genetic groups. Cultivar and the different parts of the fruit can exert an action in the definition of the quality product. The use of local varieties and ecotypes can be considered a valid tool to improve food quality and at the same time to support local agrobiodiversity.

“…The total phenolics content of the clones ranged from 72.61 mg 100 g −1 (A-11) to 147.38 mg 100 g −1 (A-19). In related studies, the total phenolics content were reported between the ranges 307.06-717.08 mg 100 g −1 for pear genotypes grown in Bosnia and Herzegovina (Duric et al, 2015), 8-140 mg 100 g −1 for pear genetic resources in Northern Japan (Ieguchi et al, 2015), 112.6-230.5 mg 100 g −1 for local pear variety grown in Ardahan (Abacı et al, 2016), 126.1-215.2 mg 100 g −1 for local pear variety grown in Posof (Erbil et al, 2018), 9.88-22.09 mg 100 g −1 for pear genetic resources in Italy (Azzini et al, 2019), 15.17-190.46 mg 100 g −1 for pear variety grown in Northeast Bosnia (Salkic et al, 2019). Findings regarding the total phenolic content showed differences rather than partial similarities with those of pear genetic resources from different countries and growing ecologies.…”

“…The antioxidant activity was determined from 2.63 mmol kg -1 (A-01 and A-09) to 4.27 mmol kg -1 (A-23) in the FRAP assay. In the FRAP assay, the antioxidant activity was determined between the ranges 0.80-3.18 mmol kg -1 for pear varieties grown in Tokat region ( Küçüker et al, 2015) and 1.20-1.61 mmol kg -1 for local pear varieties from Posof region (Erbil et al, 2018). Azzini et al (2019) reported the antioxidant activity from 1.04 mmol kg -1 to 2.91 mmol kg -1 for Italian pear genetic resources.…”

With a history of at least three centuries, ''Alişar'' is a local pear (Pyrus communis L.) variety that is widely grown in the district of Şebinkarahisar in Giresun province. In recent years, researches on the bioactive compounds of fruits that are valuable for human health has gained importance. This research was performed to determine fruit bioactive profiles of 27 clones belonging to this variety. The total phenolic content, antioxidant activity and total flavonoid content in the fruits of the clones were investigated as bioactive properties. Total phenolic contents of the clones were found between 72.61-147.38 mg 100 g -1 . In the FRAP and DPPH assays, the antioxidant activity was determined between 2.61-4.27 mmol kg -1 and 0.18-0.76 mmol kg -1 . The total flavonoid content was detected between 3.05-18.01 mg 100 g -1 . According to the FRAP assay, there was a high positive correlation (r = 0.679 ***) between total phenolic and antioxidant activity, while total phenolics showed a moderate relationship with antioxidant activity (R 2 = 0.461). The findings revealed that Alişar pear clones showed variation in fruit bioactive components, and also some clones were rich in bioactive contents. A-19 in total phenolic content, A-23 in antioxidant activity and A-18 in total flavonoid content were evaluated more remarkably than other clones. These clones are thought to contribute as genetic material to pear breeding studies.
