Öğe AFLP analysis of genetic diversity in low chill requiring walnut (Juglans regia L.) genotypes from Hatay, Turkey(Elsevier Science Bv, 2007) Bayazit, S.; Kazan, K.; Gulbitti, S.; Cevik, V.; Ayanoglu, H.; Ergul, A.In this study, the genetic relatedness of 22 low chill requiring walnut genotypes adapted to the south east Mediterranean region of Turkey was analysed by amplified fragment length polymorphism (AFLP) markers. Relatively low level of genetic variation was detected among the genotypes examined by five AFLP primer combinations, suggesting that these walnut genotypes selected predominantly for their low chill requirement have relatively narrow genetic base. In addition, the geographical proximity of the genotypes analysed was not correlated with their level of genetic relatedness. These results have implications for walnut breeding and conservation.

E.; Kazan, K.; Erguel, A.The Anatolian region of Turkey with many ecogeographical locations harbours a rich but genetically uncharacterized plum germplasm. in this study, the genetic diversity in economically important green plums (Prunus cerasifera) grown in the Mediterranean region of Turkey was assessed using the amplified fragment length polymorphism (AFLP) analysis. Overall, a relatively low genetic diversity with AFLP genetic similarity values ranging from 0.829 to 0.985 was found among the accessions studied. However, the majority of green plum genotypes derived from an ecologically distinct location within the Mediterranean region were more diverse genetically than those from other locations. In an effort to further characterize this germplasm, the same accessions were analyzed for a number of fruit quality traits. Overall, the results presented here provide useful information about the level of genetic diversity present among the previously uncharacterized plum accessions and identify germplasm that could be potentially superior to the currently cultivated plum genotypes in this plum growing region of Turkey.

Types(Int Soc Horticultural Science, 2011) Bayazit, S.; Kuden, A. B.Turkey is one of the main origins of wild and cultured almond species and cultivars due to suitable climatic conditions. Amygdalus orientalis is widely grown in Middle and Southeast Anatolia while A. turcomenica is prevalent in the Southeast Anatolia region. In this study, fruit characteristics of selected wild almond types and species in Middle and Southeast Anatolia were investigated during 2003 and 2005. The mean nut weight in types of A. orientalis. and A. turcomenica selected from Gaziantep in Southeast Anatolia region were similar in both years. Nut weights of A. orientalis types were higher than those from A. turcomenica types in Birecik, Sanliurfa. Types of A. orientalis had higher kernel weight and nut length and lower shell thickness compared to types of A. turcomenica. Types of A. orientalis from Middle Anatolia had higher nut and kernel weight, nut width and length, shell thickness compared to types from Southeast Anatolia region. All types had bitter kernel in both species and regions.Öğe Fruit Yield and Quality Performance of Low Chilling Nectarine Cultivars under Mediterranean Climate(Tarbiat Modares Univ, 2024) Caliskan, O.; Kilic, D.; Bayazit, S.This study was carried out to investigate fruit yield and quality characteristics among new nectarine cultivars grown in the eastern Mediterranean region of Turkey. 'Gardeta', 'Gartario', and 'Garofa' nectarine cultivars were cultivated on 'GN15' rootstock. The flowering stage, fruit set percentage, yield, and fruit quality properties of these cultivars were investigated between 2018 and 2021. During the study, chill requirements ranged between 391 and 600 chilling hours and between 207 and 361 chill units in the area, and huge values were obtained for the average initial fruit set above 60% and the final fruit set above 45%. 'Gardeta' had the highest cumulative yield per tree (80.15 kg tree-1) and cumulative yield per hectare (133.04 tons ha(-1)). The fruit size, Total Soluble Solids (TSS) content, and fruit coloration were homogeneously distributed in all three cultivars. In addition, the Flowering (F) and Initial Fruit Set (IFS) characters were negatively correlated with Fruit Weight (FW), Fruit Length (FLE), and Fruit Diameter (FD). As a result, the 'Gardeta' was found remarkable with late flowering, the highest yield, and superior fruit quality characteristics such as size, red skin color, and high TSS/total acidity values in the eastern Mediterranean region of Turkey. In addition, the date of Full Flowering (FF) and Fruit Firmness (FF) were negatively correlated with fruit Skin color L* (SL), C (SC), and h degrees (SH) variables. The results demonstrated that the new nectarine cultivars used here showed changes in yield parameters and fruit quality attributes depending on the genotypic and environmental effects.Öğe Morpho-pomological and Chemical Diversity of Pomegranate Accessions Grown in Eastern Mediterranean Region of Turkey(Tarbiat Modares Univ, 2013) Caliskan, O.; Bayazit, S.Selecting within local pomegranate accessions is the main method used to identify new cultivars. Total of 76 pomegranate accessions from Hatay, Turkey, were collected and their morpho-pomological and chemical characteristics were determined. The results showed that there was significant diversity among the accessions in terms of fruit quality parameters. Several accessions were notable for their various characteristics. For example, 'Eksi 5', 'Eksiliknar', 'Kara Mehmet 1', 'Lifani 5' and 'Eksi 3' accessions could be used for extracted aril and juice as they had dark red arils and juice, good taste, and large arils. In addition, the sweet accessions 'Tatli 3', 'Tatli 13', and 'Tatli 16' with soft seeds, rosy peel, and red aril colors were very promising for fresh consumption. Our study demonstrated that there was great morpho-pomological variability among the local pomegranates grown in eastern Mediterranean region of Turkey, making them a valuable genetic source for incorporation into potential breeding programs, especially for different fruit quality characteristics.Öğe Preliminary results on morpho-pomological traits and pollinizer characterization of some caprifig genotypes grown in Eastern Mediterranean region of Turkey(International Society for Horticultural Science, 2017) Caliskan, O.; Bayazit, S.; Ilgin, M.; Karatas, N.; Kocataş, H.This study was carried out on 77 caprifig (Ficus carica var. caprificus) genotypes grown in Eastern Mediterranean region of Turkey. Caprifig fruits were harvested to determine the morpho-pomological and pollinizer characteristics in 2014. Significant phenotypic diversity was detected among caprifig genotypes based on the fruit quality traits. Fruit weight ranged between 8.96 and 55.14 g, fruit width between 30.15 and 60.43 mm, fruit length between 27.70 and 67.68 mm, ostiole width between 0.00 and 5.80 mm. The number of Blastophaga wasps per fruit resulted to be between 167.7 and 1080.8 and the number of male flowers between 6.0 and 256.4. Hatay05, Hatay08, Mersin04, Hatay16, Hatay28, Hatay06, Mersin02 and Mersin11 genotypes scored the highest overall quality according to the weighted ranked method. Our study demonstrated that there was great morpho-pomological and pollinizer variability among the caprifigs grown in eastern Mediterranean region of Turkey, making them a valuable genetic source for incorporation into potential breeding programs and also caprification application.Öğe RAPD analysis of genetic relatedness among selected quince (Cydonia oblonga MiIL) accessions from different parts of Turkey(2011) Bayazit, S.; Imrak, B.; Küden, A.; Kemal Güngör, M.Quince (Cydonia oblonga Mill.) is a minor fruit crop, which is primarily used for marmalade, jam, sauce and as rootstocks for pears. Different cultivated and local quince genotypes are grown in almost all parts of Turkey for fruit usage. In this study, randomly amplified polymorphic DNA (RAPD) technology was used to study the genetic relationships among 13 quince accessions selected from different parts of Turkey. Thirty decamer primers were used and 14 of them did not produce any polymorphism. The remaining 16 primers ranged in their amplification fragments between one (P-402, P-437, OPA 10, OPA 16, OPA 18 and OPA-19) and five (OPA-06 and OPA-07). The size of fragments varied from 100 to 1500 bp. Similarity values among the studied genotypes ranged between 0.483 and 0.925. The resulting dendrogram clustered into two groups (0.69 similarity value) based on evaluation of genetic similarities and differences. The results suggest that RAPD analysis could be used to distinguish and determine genetic variation among quince accessions. Also, the obtained clustering based on RAPD markers agreed to some extent with the geographical origin of the studied set of quince accessions.Öğe RAPD analysis of genetic relatedness among selected quince (Cydonia oblonga Mill.) accessions from different parts of Turkey(Czech Academy Agricultural Sciences, 2011) Bayazit, S.; Imrak, B.; Kuden, A.; Gungor, M.
