Genetic Relationships Among Olive (Olea europaea L.) Cultivars Native to Turkey

AbstractOlive is a widely cultivated, mainly in the Mediterranean region, and economically important fruit species used as both olive oil and table olive consumption. In Turkey, more than 50 olive cultivars have been authorized for commercial plantations, representing the developmental base for the olive industry. The aim of the present study was to identify genetic relationships among the most widely grown 27 olive cultivars in Turkey, using microsatellite or simple sequence repeat markers. Nine well-known foreign olive cultivars from different countries are also included in the study to compare the Turkish cultivars. To determine genetic relationship and diversity, 10 SSR loci (DCA3, DCA9, DCA15, DCA18, UDO4, UDO9, UDO11, UDO12, UDO24, UDO28) were used. Jaccards similarity coefficient and the UPGMA method for cluster analysis were performed using the software NTSYSpc. The results showed that the number of alleles per locus ranging from 4 (UDO4, UDO9, UDO11, UDO12, DCA15) to 12 (DCA9) presenting high polymorphism. There were no identical cultivars. High similarity was shown by cultivars Maviand Adana topağı (0.754). The most genetically divergent cultivars, Domat-Meski (0.240) and Domat-NizipYağlık (0.245), were also identified.

The Investigation of Relationships Between Some Fruit and Kernel Traits with Canonical Correlation Analysis in Ankara Region Walnuts

Canonical correlation analysis is a multivariate technique, which is employed to examine relationships between two variable sets, each of that consist of two or more variables. In the analysis, by maximizing the relationships between two sets, it is aimed to obtain new variables called as canonical variates that formed by linear combinations of the original variables for each sets. In this study, it is aimed to examine the relationships between some fruit and kernel characteristics of Ankara region walnuts. Thus, the following eight traits Fruit Length (mm), Fruit Width (mm) Fruit Height (mm) Fruit Weight (g), Shell Thickness (mm), Kernel Weight (g), Kernel Ratio (%) and Filled-firm Kernel Ratio (%) of 364 walnut samples were measured. First five of these characteristics were grouped as X variable and the rest of as Y variable. As a result, the correlation between the first canonical variable pair was found as 0.979 (p < 0.01).ZusammenfassungDie kanonische Korrelationsanalyse ist eine multivariate Methode, die zum Einsatz kommt, wenn der Zusammenhang zwischen zwei Sätzen von Variablen, die jeweils wieder aus zwei oder mehr Variablen bestehen, untersucht werden soll. Um eine maximale Korrelation zwischen den beiden Sätzen von Variablen zu finden, zielt die Varianzanalyse darauf ab, neue Variablen zu erhalten, die kanonische Variablen heißen. Sie werden aus Linearkombinationen der beiden ursprünglichen Sätze an Variablen ermittelt. Es ist Ziel dieser Untersuchung, den Grad des Zusammenhangs zwischen einigen Merkmalen von Frucht und Kern (Walnuss) von Walnussbäumen aus der Region um Ankara zu bestimmen. In diesem Zusammenhang wurden von 364 Walnussbäumen Proben gesammelt, von denen Frucht-Länge (mm), Frucht-Querschnitt (mm), Frucht-Größe (mm), Fruchtgewicht (g), Schalen-Dicke (mm), Nusskern-Gewicht (g) und Nusskern-Anteil (%) gemessene wurden und es wurde ermittelt, wie stark der Nusskern-Anteil die Frucht ausfüllt (%). Fünf dieser Merkmale wurden als X-Variablen, die restlichen Variablen als Y-Variablen gruppiert. Zwischen dem ersten kanonischen Variablen-Paar wurde als Ergebnis eine Korrelation von 0,979 (p < 0.01) gefunden.

Erratum to: Determination of Pomological and Morphological Characteristics with Fatty Acid Composition of High Kernel Ratio Walnut Genotypes

In this selection survey that was performed to select the types with superior properties among the population of seedling walnut trees in Cankiri location, fruit samples were collected individually from 67 trees. Than these types were evaluated for fruit and tree properties and eight walnut types with fruit weight between 11.90 and 15.83 g, interior weight between 6.66 and 8.82 g, the interior ratio between 53.06 and 60.41 %, shell thickness between 1.21 and 1.50 mm were selected as promising. For these types the shell color was determined as dark in two types and tawny in six types. The inner color was found to be light yellow in four types and dark yellow in four types. The selected types were in a good condition for full and sound interior ratio. Seven types gave 100 % full and sound inner. Whereas one type gave 20 % empty fruit. Four types showed homogamous blooming, one types showed protandrous blooming and three types displayed protogynous blooming. The total oil content of selected types varied from 43.16 to 58.68 %. The range of fatty acid contents in the fruits of these types were also determined between 50.83 and 60.77 % for linoleic acid, between 16.14 and 26.44 % for oleic acid, between 5.42 and 7.29 % for palmitic acid, between 11.08 and 14.25 % for linolenic acid and between 1.70 and 2.55 % for stearic acid.

Şırnak İli Zeytin Gen Kaynaklarının Morfolojik, Pomolojik Özellikleri İle Yağ Asidi Kompozisyonlarının Belirlenmesi

Ulkemiz Guneydogu Anadolu Bolgesi’nde yer alan Şirnak ilindeki zeytin gen kaynaklarinin olusturdugu populasyon icerisinden ustun nitelikli olanlari belirlemek amaciyla gerceklestirilen calismada, 34 genotipten surgun, yaprak ve meyve ornekleri alinmistir. Belirlenen genotiplerde agac, meyve ve yaprak ozellikleri ile toplam yag ve yag asitleri kompozisyonlari incelenmistir. Şirnak ili genotiplerinin cogunlukla dik ve yari dik tac yapisinda ve tiplerin cogunlugunun eliptik uzun sekilli yapraga sahip olduklari gorulmustur. Incelenen tiplerde meyve agirligi 0.70 g (Deran5)-4.20 g (Serekani) ve meyve sekli tiplerin cogunlugunda eliptik olarak belirlenmistir. Toplam yag orani % 2.0 ile % 8.8 arasinda bulunmustur. Yag asitleri miktarlari, palmitik asit %12.57 (Karkamis3)-%19.82 (Oguzeli1), stearik asit %2.31 (Islahiye1)-%4.23 (Araban2), oleik asit %58.68 (Oguzeli3)-%72.86 (Karkamis3), linoleik asit %5.10 (Araban1)-%21.06 (Oguzeli3) ve linolenik asit %0.73 (Oguzeli1)-%1.71 (Nizip9, Nizip10) olarak belirlenmistir.
