    ASSESSMENT OF RELATIONSHIP BETWEEN FRUIT CHARACTERISTICS OF ALMOND SELECTIONS FROM AYDIN REGION USING CANONICAL CORRELATION ANALYSIS METHOD
    (Parlar Scientific Publications (P S P), 2018) Gulsoy, Ersin; Simsek, Mikdat; Kara, Mehmet Kazim; Balla, Fikri
    Selection of promising genotypes possessing superior yield and quality traits among the rich almond seedling population in Turkey is necessary for increasing the contribution of these genotypes to the Turkish economy through propagation. It is also important to consider the relationship between yield and quality traits when making this selection. The aim of this study was to determine the relationship between two sets of variables created considering characteristics of fruit and kernel of almond by using the canonical correlation analysis method, which is one of the multivariable analysis methods. In this method, the relationship between two canonical variables and the major variables of the same set was examined. It was concluded that the increase in fruit weight (FWe) and fruit thickness (FT) led to a significant decrease in kernel weight (KWe) and kernel ratio (KR).

    Determination of Fatty Acids, ?-Tocopherol, ?-Caroten, Minerals, and Some Pomological Properties of Walnut Genotypes Selected from Aras Valley (Eastern Turkey)
    (Jihad Daneshgahi, 2019) Gulsoy, Ersin; Pehluvan, Mucahit; Simsek, Mikdat
    Fatty Acids, alpha-tocopherol, beta-caroten, minerals, and some pomological properties of walnut genotypes from four locations (Igdir, Tuzluca, Karakoyunlu, Kagizman) of Aras Valley (Eastern Turkey) were examined. In this study, the differences among the genotypes were determined in terms of some fruit characteristics, oil and protein contents, fatty acid composition, selenium content, alpha-tocopherol content, beta-carotene content and some macro- and micro- element contents. The genotypes different in the values of nut weight from 8.89 to16.22 g, kernel weight from 4.72 to 9.64 g, kernel ratio from 36.74 to 59.59%, and shell thickness 1.04-3.60 mm, respectively. The contents of fat and moisture of the selected genotypes were in the range of 59.18 to 68.12% and 10.49 to 23.31%, respectively. The contents of most common fatty acids determined in the genotypes were linoleic acid (58.15-64.07%), oleic acid (12.93-17.49%), linolenic acid (9.37-13.61%), palmitic acid (5.60-8.62%) and stearic acid (4.68-6.69%), whereas the contents of remaining fatty acids were rarely detected in trace amounts. In the genotypes, the amount of alpha-tocopherol was in the range of 8.75 to 35.11 mg/kg, ) beta-carotene was in the range of 0.03 to 0.12 mg /kg and selenium was in the range of 15.89 to 68.19 ng/g. The genotypes were found to have 1.09 to 2.47% N, 230.36 to 451.48 mg/100g P, 350.74 to 666.20 mg/100g K, 2.30 to 3.86 mg/100g Cu, 1.71 to 3.91 mg/100g Zn, 7.16 to 18.82 mg/100g Fe, 144.0 to 452.08 mg/100g Ca, 110.25 to 342.44 mg/100g Mg, 1.73 to 9.67 mg/100g Mn and 7.11 to 25.51 mg/100g Na. The present results revealed that the high nutritional values of walnut genotypes selected from the Aras Valley(Eastern Turkey) could have health benefits effects on human nutrition.

    Heavy Metal Levels and Risk Assessment of Walnut Genotypes ( Juglans regia L.) Grown in Aras Basin of Turkiye
    (Hohere Bundeslehranstalt & Bundesamt Wein-& Obstbau Klosterneuburg, 2024) Gulsoy, Ersin; Pehluvan, Mucahit; Simsek, Ugur; Sanda, Murad Aydin; Simsek, Miktat
    Walnuts are among of the most popular nuts worldwide due to their health-promoting compounds, and their consumption is on the rise. This increase in walnut consumption may lead to an increase in the intake of heavy metals in the body. In this study, the levels of the heavy metals Cr, Ni, Pb and Cd were determined in a total of twenty walnut genotypes grown in four different locations in the Aras Basin, and the distribution of these heavy metals according to location was analyzed. While highly significant differences (P<0.001) were found among the walnut genotypes in terms of heavy metal contents, the distribution of these metals among the sites showed differences (P <= 0.05). The average amounts of Cr, Ni, Cd and Pb in the walnuts were 476.00 mu g kg(-1), 202.83 mu g kg(-1), 2.06 mu g kg(-1) and 30.64 mu g kg(-1), respectively. All heavy metals analyzed according to location showed the highest values in Tuzluca. As a result, since the hazard quotient (HQ) which derived from the daily intake rate (DIR) of each trace element analyzed was less than 1(HQ<1), it was found that the investigated walnut genotypes were not risky for human health.

    IDENTIFICATION AND SELECTION OF SOME FEMALE FIG (FICUS CARICA L.) GENOTYPES FROM MARDIN PROVINCE OF TURKEY
    (Pakistan Botanical Soc, 2017) Simsek, Mikdat; Gulsoy, Ersin; Kirar, M. Zeydin; Turgut, Yusuf; Yucel, Bedriye
    Female fig genotypes in the Beyazsu region located between Nusaybin and Midyat districts (Mardin) in Turkey were selected using the weighted ranking method during years 2014-2015. Each selected genotype was identified. The total scores of the genotypes varied from 704 to 950. Fruit weight ranged from 47.68 to 72.68 g, ostiole width from 1.53 to 5.96 mm, total soluble solids (TSS) from 20.67 to 23.87% and acidity from 0.18 to 0.23%. All the genotypes had long petioles and green shoots. The leaf lobe shape was lyrate in two genotypes named MBSU16 and MBSU23, and latate in the rest of the genotypes. The tree growth habit was open in two genotypes named MBSU16 and MBSU24 but spreading in other genotypes. In conclusion, two genotypes MBSU11 and MBSU21 scored the highest in overall quality. These two genotypes should be preserved as genetic resources for future breeding programs.

    A RESEARCH ON DETERMINATION SOME BOTANICAL, POMOLOGICAL AND CHEMICAL PROPERTIES OF WALNUT GENOTYPES (JUGLANS REGIA L.) GROWN IN EASTERN TURKEY
    (Parlar Scientific Publications (P S P), 2018) Simsek, Mikdat; Gulsoy, Ersin; Pehluvan, Mucahit; Erdogmus, Berrin
    Some botanical, pomological and chemical characteristics of promising walnut (Juglans regia L.) genotypes grown in Bingol province of Eastern Turkey were studied. The pomological properties of the walnut genotypes were attributed to the quality criteria of nuts. Fruit weight, kernel weight, fruit length, fruit width, fruit height, kerrnel ratio, shell thickness and shape index were determined as 10.88-15.35 g, 5.56-8.36 g, 33.72-42.79 mm, 30.88-37.49 mm, 30.90-35.79 mm, 48.12-54.51%, 1.07-1.42 mm and 1.07-1.25, respectively. The kernel color and fruit size were light yellow or dark yellow, and extra of all the genotypes. The fruits were found to be rich in crude protein and crude oil. The total ash, moisture, crude oil, crude protein total carbohydrate and total energy contents were determined as 1.31-2.05%, 3.15-3.91%, 63.62-66.78%, 14.54-17.53%, 11.54-15.53% and 698.18-712.87 kcal, respectively. Fruitful laterals ranged from 50 to 80% while harvest date ranged from 1-30 October. The flowering habits observed as 7 protandrous, 3 protogynous and 2 homogamous of the promising genotypes. The results might contribute to breeding studies in order to identify better walnut genotypes, the commercial production for the farmers in both this region and the other region of our country, and healthy diets in future.
