Virgin Oil Characteristics for Selected Clones From 'Arbequina' Variety

Using Nutritional Lipid and Sensorial Profiles for the Characterization of Turkish Olive (Memecik X Gemlik cv) Hybrids obtained from Controlled Crossbreeding

“…The fatty acid profile, especially LO (omega-6) and LNA (omega-3), of Turkish olive hybrids (Gemlik and Memecik) were generally in good agreement with the previous studies in which the values determined from Italian breeding programs (Alfei et al, 2008;Ranalli et al, 2000Ranalli et al, , 2006Ranalli et al, , 2008Ripa et al, 2008), Spanish IRTA 18 clone results (Riachy et al, 2012;Romero et al, 2008), and also the findings of oils of olive selections derived from a Tunisia olive breeding program (Dabbou et al, 2012;Manai et al, 2006Manai et al, , 2007. In addition, nutritional fatty acid profile of Turkish olive hybrids and their parents were generally similar to the findings of Turkish researchers domestic olive hybrids (Özdemir et al, 2013) and Memecik and Gemlik cultivars (U gurlu Aşık and Özkan, 2011; Yorulmaz et al, 2014), another study of commercial oils (Diraman and Hisil, 2004).…”

“…According to official norms, the amount of TFA in virgin olive oils should be a maximum 0.1%. The variations in FA composition of the Turkish olive hybrids (Gemlik X Memecik cv) grown under pedoclimatic conditions may originate from genetics of olive cultivars and also partly enviromental factors especially seasonal changes based on harvest years (Dabbou et al, 2012;Manai et al, 2006;Ranalli et al, 2008;Riachy et al, 2012;Romero et al, 2008). In this study, significant correlations (P < 0.05) were determined between fatty acid variables and their some parameters.…”

“…In recent years, although there are remarkable studies made in Spain, Italy, Tunisia, and Israel on olive breeding and hybridization, there is no information about oil properties of Turkish olive hybrids together with their parents in the literature. A few new olive genotypes and hybrids were recently developed in Spain for example, IRTA-18, a clone Arbequnia and olive hybrids obtained from Arbequnia, Picual, and Frantoio (León et al, 2011;Riachy et al, 2012;Romero et al, 2008), in Israel (Askal, a hybrid originated from Barnea X Manzanillo) (Lavea et al, 2003) and in Italy (FS17 and I-77 hybrids from Frantoio variety and unknown Italian olive variety, respectively) (Ranalli et al, 2000(Ranalli et al, , 2006(Ranalli et al, , 2008 and also in Tunisia (promising some hybrids obtained by controlled crosbreedig from Chemlali and Chetoui cultivars) (Dabbou et al, 2012;Manai et al, 2006Manai et al, , 2007 by means of these studies. The first selection findings of the Turkish olive breeding project (Gemlik X Memecik and Memecik X Gemlik) were reported based on agronomic and phenological results by Ersoy et al (2008).…”

Elicitors: A Tool for Improving Fruit Phenolic Content

“…In lemon, improvements in bioactive compounds in the juice, such as vitamin C and flavonoids, may be achieved by selecting specific clones [32]. In a screening of 15 olive tree clones, some were found to have high total polyphenol, oleic and linoleic acid contents [33]. The vitamin C, total carotenoid, total anthocyanin, yellow flavonoids and polyphenol contents and total antioxidant capacity were analyzed in clones of cashew apples, and differences were found between clones [34,35].…”
