Öğe Analysis of Fruit Properties of 'Hacihaliloglu' x 'Boccucia' Hybrid Population(Springer, 2020) Bilgin, Nihal Acarsoy; Evrenosoglu, Yasemin; Misirli, Adalet; Kokargul, RemziApricot is an important fruit species cultivated in the world. Different varieties of apricot with various quality and sensory characteristics that vary according to the countries are consumed. It is important to breed new varieties to meet consumer demands. Therefore, in this study that was conducted with the 'Hacihaliloglu' x 'Boccucia' population to develop new varieties at a later stage, physical, chemical sensory characteristics of the hybrid population were investigated and the status of the population through PCA (Principal Component Analysis) and CA (Clustering Analysis) upon determining the correlation between properties evaluated. Significantly, high levels of variation were observed regarding fruit weight, color, firmness and harvest time. Fruit color and harvest time have been distinctive parameters in selecting genotypes. the dendrogram obtained from cluster analysis grouped 20 genotypes in the same group while the other genotypes were placed in a separate group.Öğe Analysis of Fruit Properties of 'Hacihaliloglu' x 'Boccucia' Hybrid Population (vol 10, pg 421, 2020)(Springer, 2020) Bilgin, Nihal Acarsoy; Evrenosoglu, Yasemin; Misirli, Adalet; Kokargul, RemziThe article Analysis of Fruit Properties of 'Hacihaliloglu' x 'Boccucia' Hybrid Population, written by Nihal Acarsoy Bilgin, Yasemin Evrenosoglu, Adalet Misirli and Remzi Kokargul, was originally published electronically on the publisher's internet portal (currently SpringerLink) on 25th February horizontal ellipsisÖğe An Analysis on Some Reciprocal Pear Hybridization Combinations in Terms of Transferring Resistance to Fire Blight(Springer, 2020) Evrenosoglu, Yasemin; Mertoglu, Kerem; Bilgin, Nihal Acarsoy; Misirli, Adalet; Altay, YasinSince it has a wide variety, pear can be grown in all temperate zones and high-altitude areas of tropical and subtropical climates of the Earth. on the other hand, most of the cultured pear varieties are susceptible to fire blight caused by Erwinia amylovora, and their susceptibility is threatening pear cultivation. the lack of a certain solution to fire blight, the harmful effects of the chemicals on environment and human health and the increasing demand for organic products, give priority to breeding new resistant rootstocks and varieties in control of the disease. Due to the polygenic nature of fire blight resistance and the complexity of its mechanism, controlled hybridization is generally used in breeding programs. in order to determine the effect of the parents for the transmission of fire blight resistance, hybridizations are also carried out reciprocally. in the study which was carried out for this aim, susceptibility levels of the F1 hybrids, obtained from the reciprocal combinations of fire blight resistant 'Kieffer' and the susceptible 'Williams', 'Santa Maria' and 'Akca' cultivars, were evaluated. While 'Kieffer' x 'Santa Maria' was found the most resistant combination to fire blight, 'Akca' x 'Williams' was found as the most susceptible one. in addition, it has been determined that F-1 hybrids obtained from 'Kieffer' x 'Santa Maria' and 'Akca' x 'Williams' hybridization combinations and their reciprocals are different in terms of disease resistance, while there was no difference in resistance in F-1 hybrids of 'Williams' x 'Santa Maria' combination and its reciprocal combination.Öğe Evaluation of Fire Blight (Erwinia amylovora) Disease Reaction of Pear Hybrid Combinations(Ankara Univ, Fac Agr, 2017) Evrenosoglu, Yasemin; Misirli, Adalet; Aysan, Yesim; Saygili, Hikmet; Boztepe, Ozlem; Horuz, Sumer; Bilgin, Nihal Acarsoy; Bilen, Emre; Baykul, AliFire blight caused by pathogenic bacterium Erwinia amylovora, is the serious disease of pear. Since there is no effective chemical management to this disease except antibiotic-type compounds, it is very important to improve new fire blight resistant cultivars. In this research, it was aimed to select and develop fire blight resistant pear types and to determine fire blight susceptibility levels of pear hybrids, obtained from different projects. Hybrid plants were inoculated by shoot injections twice each year. Evaluations were made through necrotic shoot rate and susceptibility levels of hybrids were determined. During the experiments, 7036 hybrid pear seedlings inoculated, and 12.28% of them were found as "very low susceptibility" (A), 3.62% as "low susceptibility" (B) classes.Öğe Evaluation of Susceptibility of Different Pear Hybrid Populations to Fire Blight (Erwinia amylovora)(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2011) Evrenosoglu, Yasemin; Misirli, Adalet; Saygili, Hikmet; Bilen, Emre; Boztepe, Ozlem; Acarsoy, NihalFire blight disease caused by pathogenic bacterium Erwinia amylovora, is the serious disease of pear, and there is not a certain chemical management against this disease except antibiotic-type compounds such as streptomycin. It is very important to improve new fire blight resistant cultivars in case of integrated disease management. With this purpose, different crosses have been made between Pyrus communis varieties that have good fruit characteristics and resistant cultigens. Besides, self and open pollination treatments have been carried out in maternal plants. The disease resistance level of the hybrids obtained from these combinations was determined by artificial inoculations by Erwinia amylovora in greenhouse conditions. A total of 3284 hybrids were inoculated, and 2631 of them survived and were distributed to different susceptibility classes. 19.88% of the inoculated hybrids was killed by Erwinia amylovora. Total distribution of the hybrids to susceptibility classes was as 6.18% in class "A- slightly susceptible", 3.11% in class "B- less susceptible", 8.89% in class "C- mid-susceptible", 20.28% in class "D- susceptible; and 61.54% in class "E- very susceptible". Majority of class "A- slightly susceptible" hybrids were obtained from 'Magness' x 'Ankara' combination. 'Kieffer' a 'Santa Maria', 'Kieffer' open pollination, 'Magness' x Aka; 'Magness' a 'Kieffer', 'Magness' x 'Santa Maria', 'Mustafa Bey' x 'Moonglow' treatments displayed good results with respect to 'A- slightly susceptible" character. It is very important to evaluate these hybrid pear populations through different fruit and tree characteristics in the future.Öğe FRUIT CHARACTERIZATION AND EVALUATION OF F-1 HYBRIDS IN HACIHALILOGLU X IVONNE LIVERANI COMBINATION(Parlar Scientific Publications (P S P), 2020) Evrenosoglu, Yasemin; Bilgin, Nihal Acarsoy; Misirli, AdaletApricot is a type of fruit with high consumer demand because it is evaluated as table and dried. Different eco-geographic groups have varieties with superior characteristics. This situation is very important in terms of creating wide variations in breeding studies. in the current research, pomological and biochemical properties of 45 apricot hybrids obtained from the parental combination of Hacihaliloglu X Ivonne Liverani were analyzed and identified. Variation was determined related to investigated characteristics among apricot genotypes. the data were evaluated by PCA (Principal Component Analysis) and CA (Clustering Analysis) upon determining the correlation between properties. 10 PCA were obtained, and they defined 78.12% of the population with 27 characteristics. the highest correlation was stated between fruit weight and width. Hybrids were with small sized, orange color, free and sweet kernel. the organoleptic properties of most hybrids are at acceptable levels.Öğe Genetic Variability and Association Analysis of Some Quantitative Characters in Sweet Corn(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2013) Alan, Ozlem; Kinaci, Gulcan; Kinaci, Engin; Kutlu, Imren; Budak Basciftci, Zekiye; Sonmez, Kenan; Evrenosoglu, YaseminThe objective of this study was to determine genetic variability, heritability, genetic advance, genotypic and phenotypic correlations of yield, yield components and kernel quality traits in seven sweet corn varieties. The present research was conducted during 2009 and 2010 growing season in Eskisehir, midwestern Turkey. The trials were set up in randomised complete block design with four replications. Analysis of variance observed highly significant differences for all the examined traits in both years. Sugar content, soluble solid concentration and number of leaves per plant revealed the highest genotypic and phenotypic coefficient of variation values. The high heritability estimates coupled with high generic advance for sugar content, soluble solid concentration and starch content. Positive correlations were revealed between yield (husked, dehusked and fresh kernel) and yield components except plant height and 1000 seed weight. Negative correlations were found between kernel quality and yield and yield related traits. It can be concluded that, husked ear weight and dehusked ear weight could be used as the main criteria for yield improvement. It should be unfeasible to develop sweet corn varieties with satisfactory yield potential and improved kernel quality for the different sweet corn markets.Öğe Inheritance pattern of fire blight resistance in pear(Elsevier Science Bv, 2019) Evrenosoglu, Yasemin; Mertoglu, Kerem; Bilgin, Nihal Acarsoy; Misirli, Adalet; Ozsoy, Abdullah NuriFire blight caused by Erwinia amylovora is a serious disease that directly affects pear agriculture and production around the world. The most effective way to struggle with disease is develop new varieties and rootstocks. In this study, for a better understanding of the genetic base of fire blight such as heritability of disease resistance, breeding values of parents and maternal effect were investigated on F-1 hybrid pear population. According to results, disease resistance shows polygenic inheritance and multiple factors were effective in heredity. Resistance to disease is transmitted to next generations by both parents. However, the influence of the female parent on inheritance is much greater than pollinator. 'Magness' and 'Mustafa Bey' varieties were found more effective for the transmission of disease resistance as female parents to next progenies. Similar results were obtained from 'Kiefer' and 'Limon' as pollinator. In addition to the importance of the parents exclusively in disease resistance, gene interactions between the parents also had a significant effect on this matter. Heritability of fire blight that was calculated from the non-additive genes was 23%, likewise 32% was calculated from additive genes. Broad sense heritability of fire blight, representing the sum of this two situations was 55%. Maternal gene effects were greater than the pollinator and maternal effect had a 7% effect on the disease resistance, indicating that the cytoplasmic gene effects had important roles in the resistance. Obtained results will form basis for the development of new varieties that become resistant to fire blight by hybridization.Öğe Investigations on fertilization biology and description of fruit characteristics of some persimmon (Diospyros kaki) cultigens(Academic Journals, 2011) Evrenosoglu, Yasemin; Acarsoy, Nihal; Misirli, AdaletPersimmon is a fruit that has increasing importance on export and prefer to be consumed because its taste, nutrient content and appearance. It can be grown at different ecological conditions without discerning climate and soil. In this sense, it is important to encourage persimmon cultivation. Pollinators need to be used for a good fruit set on cultural varieties. In this study that prepared from this point of view, fertilization biology, phenological and pomological observations were performed on Hachiya and Fuji cultivars that pollinated with different male types in demis/Izmir-Turkey. Additionally, viability (TTC and IKI) and germination tests were carried out. Consequently, it was observed that fruit set increased when pollinators were used.Öğe Investigations on the Pollen Morphology of Some Fruit Species(Tubitak Scientific & Technical Research Council Turkey, 2009) Evrenosoglu, Yasemin; Misirli, AdaletMorphological characters are used to identify plant material. Pollen morphology is an important parameter. This is of great importance in detailed investigations by scanning electron microscope (SEM). In order to develop a plant material identification tool, this research was carried out to determine the pollen morphology of some fruit species using SEM on apple, pear, quince, apricot, plum, peach, almond, chestnut, walnut, pomegranate, and persimmon cultivars. The surface features, as well as length, width, and P/E ratio of pollen were observed. Pollen length and width changed with investigated species and cultivars; the longest and widest pollen grains were detected in peach and walnut, respectively. The pollen. according to P/E ratio, was prolate. suboblate. and perprolate based on the material. Regarding the surface features. the ornamentation of pear, quince. plum, peach, and almond pollen was striate and tectum perforatum, whereas that of apple, chestnut, apricot and pomegranate was striate, rugulate, and tectum imperforatum. Walnut and persimmon had special surface characteristics.Öğe Kernel Quality of Some Sweet Corn Varieties in Relation to Processing(Univ Agr Sci & Veterinary Med Cluj-Napoca, 2014) Alan, Ozlem; Kinaci, Gulcan; Kinaci, Engin; Basciftci, Zekiye Budak; Sonmez, Kenan; Evrenosoglu, Yasemin; Kutlu, ImrenThe quality characteristics (dry matter content, soluble solid concentration, kernel colour, sugar, starch and protein content) of fresh, frozen and canned kernels of seven sweet corn varieties ('Lumina', 'Merit', 'Sunshine', 'Jubilee', 'Challenger', 'Yellow Baby' and '2201') were studied. The present research was conducted during 2009 and 2010 in Eskisehir, Midwestern Turkey. The trials were set up in randomised complete block design, with four replications. Ears were harvested and randomly selected for analysis as fresh, frozen and canned. Dry matter content ranged from 34.2% ('2201') to 39.5% ('Yellow Baby), soluble solid concentration from 16.3% ('2201') to 27.4% ('Yellow Baby'). The sugar content of fresh kernels was higher than other treatments (frozen and canned) for all varieties. The starch content of the varieties was decreased after processing, except in 'Yellow Baby'. Fresh, frozen and canned sweet corn kernels had similar protein contents; the highest protein content was obtained, for all treatments, from 'Challenger', and it maintained its higher protein content after processing. '2201' had the highest sugar and the lowest starch content for fresh, frozen and canned varieties. When compared on a kernel basis, sweet corn marketed as fresh, frozen or canned, it may be feasible to select varieties for different sweet corn markets.Öğe Leaf phenolic content of some squash rootstocks used on watermelon (Citrullus lanatus (thunb.) Matsum and Nakai) growing and phenolic accumulation on grafted cultivar(Academic Journals, 2010) Evrenosoglu, Yasemin; Alan, Ozlem; Ozdemir, NilayIn this study, phenolic compounds were identified in the leaves of grafted and non-grafted watermelon (Citrullus lanatus (Thunb.) Matsum and Nakai) plants and squash rootstocks. The watermelon cultivar 'Crispy' was grafted onto hybrids of C. maxima x C. Moschata, 'TZ-148' and 'RS-841', and Lagenaria siceraria cv. '64 - 18'. The experiments were conducted in a randomized complete blocks design in two time periods. Non-grafted plants were used as the control. Some important differences were detected for the contents of the phenolic compounds during the growing periods such as kaempferol accumulates in the leaves of grafted and non-grafted watermelon plants and rootstocks. Kaempferol contents of the rootstocks were found to be higher than the grafted and non-grafted watermelon plants. Plants grafted on 'TZ-148' or 'RS-841' had higher phenolic content than the others.Öğe Prunasin contents of Turkish apricot cultivars and artificial infestation of rootstocks by Capnodis tenebrionis (Linnaeus, 1758) and Capnodis carbonaria (Klug, 1829) (Coleoptera: Buprestidae)(Entomological Soc Turkey, Ege Univ, 2011) Tezcan, Serdar; Evrenosoglu, Yasemin; Misirli, Adalet; Gulcan, Ruhinaz; Gulpercin, NilayThese studies were conducted in Izmir (Bornova) under natural conditions with three years old rootstocks grown in pots. One-day old neonates were used for artificial infestations of different apricot rootstocks and 5 neonates of Capnodis tenebrionis (Linnaeus, 1758) were given per rootstock for artificial infestation. The same procedure was followed for infestation of C. carbonaria (Klug, 1829). Relationship has not been determined between prunasin compounds of roots and infestation, but it has been determined prunasin accumulation between varieties. The percentage of C. tenebrionis infested saplings and the number of larvae per sapling arranged from the highest to the lowest for cultivar as follows: Sekerpare > Soganci > X1 Zerdali > Kabaasi > Tokaloglu > Adilcevaz 2 > X2 Zerdali > Sam > Adilcevaz 1 > Hacihaliloglu > Adilcevaz 4 > Hasanbey while the percentage of C. carbonaria infested saplings and the number of larvae per sapling arranged from the highest to the lowest for cultivars as follows: Adilcevaz 1 > Adilcevaz 2 > X2 Zerdali > X1 Zerdali > Hacihaliloglu > Soganci > Hasanbey > Sam > Adilcevaz 4.
