This study was carried out in Muş province and its districts between 2020-2022. In the study, phenological, pomological and chemical properties of local pear cultivars grown in Muş ecological conditions were obtained. In the region where 42 different local pear varieties determined as a result of the studies were grown, the superior local varieties within the scope of the study were determined by using the "Weighed Rating" method. In order to compare these local varieties with each other, 24 local pear cultivars were selected with superior characteristics in terms of fruit weight, eating quality, external appearance, rustiness, water-soluble dry matter content and fruit flesh hardness as a result of the weighted grading made in 2020. These 24 selected varieties were compared according to the weighted grading results in 2021 and finally 13 local pear varieties were determined as promising. Among the promising local pear cultivars, Güz Armudu-1, Paşa Armudu-2 and Sulu Armut cultivars received the highest scores, respectively. It is aimed to increase the quality of the promising local pear varieties, thus to protect genetic resources and to reveal genotypes that may be candidates for registration. [ABSTRACT FROM AUTHOR]

The main objective of this study was to evaluate the fruit quality characteristics and biochemical properties of Mondial Gala, Jeromine, and Granny Smith cultivars grafted on M9 full-dwarf clonal rootstock and Granny Smith, Fuji, Galaxy Gala, Red Chief, and Scarlett Spur cultivars grafted on MM 106 semi-dwarf clonal rootstock grown in Ordu (Türkiye) ecological conditions. During the research, fruit weight, fruit dimensional characteristics, fruit firmness, color characteristics, soluble solids content, titratable acidity, pH, vitamin C, total phenolic, total flavonoid and antioxidant activity of the cultivars were investigated. In the study, it was determined that, fruit weight, fruit firmness, SSC and Vitamin C 185.40 g (Mondial Gala/M9)- 284.03 g (Scarlet Spur/MM 106), 69.73 N (Galaxy Gala/MM 106)-84.47 N (Granny Smith/M9), 8.29% (Scarlett Spur/MM 106)-14.27% (Fuji/MM 106), 58.00 mg (Scarlet Spur/MM 106)-112.33 mg (Granny Smith/M9), respectively. In addition, it was determined that Granny Smith, Red Chief, Mondial Gala, and Jeromine cultivars stand out in terms of bioactive compounds that positively affect human health compared to other cultivars. As a result, it has been revealed that apple cultivars grafted on M9 and MM 106 clone rootstocks examined in the study can be grown in high quality in Ordu ecology. [ABSTRACT FROM AUTHOR]

This research was carriedout on 5 local pear cultivars grown in and around İlkadım county (Samsun province of Turkey) in 2017. These cultivarscalled as Sarıca and Orak, and three Çörtük cultivars that have different characteristics in the region. In thesecultivars, fruit weight varied from7.6 g (Çörtük-2) to 33.0 g (Orak); fruit width from 31.55 mm (Çörtük-2) to 37.56 mm (Orak); fruit length from 36.98 mm (Çörtük-2) to 54.64 mm (Çörtük-3); fruit diameter from 31.36 mm (Çörtük-2) to 39.04 mm (Orak); fruit flesh firmness from 2.06 kg (Orak) to 7.77 kg (Sarıca); total soluble solid content from9.9% (Orak) to 14.7% (Çörtük-3); pH value in fruit juice ranged from 4.77 (Sarıca) to 5.39 (Orak) and titratable acidity from 2.10 % (Orak) to 5.19% (Çörtük-2).

This study was carried out to investigate pomological properties of local apple genotypes in Tokat province, in 2015 and 2016. Some properties of 23 local apple genotypes from survey studies were determined. In the genotypes analysed; the pomological properties were ranged as; 83.31-249.78 g for fruit weight, 57.67-85.50 mm for fruit diameterand 47.93-67.23 mm for fruit length, 13.89-28.02 libre fo fruit flash hardness, 9.9-16.8 % for soluble solid content (TSS), 2.88-5.30 for pH and 0.20-1.41 % for titratable acidity. L *, a * and b * values of fruit Shell color were recorded in L * value 39.49-76.02, a * value -21.85-31.53 and b * value 19.40-46.66. [ABSTRACT FROM AUTHOR]

This study was carried out in Çaykara county (Trabzon province, Turkey) and in its 25 districts during 2012-2013 years. In the research, pomological characteristics of localpeargenotypesgrown for many years were examined. 169 local pear genotypes were determined in the research. According to weighted-ranked method done based on fruit weight, rustiness, eating quality and appearance, 97 local pear genotypes were selected superior genotypes in 2012. In the study genotypes according to the first year harvest dates were divided into 3 groups as summer, autumn and winter seasons. Total 34 local pear genotypes (18 summer, 9 autumn and 7 winter seasons) were determined as promising according to weighted-ranked method in 2013. In the promising summer, autumn and winter genotypes, fruit weight were between 81.3 g-148.7 g, 88.5 g-155.7 g and 69.9 g-221.4 g,respectively; fruit width were between 49.9 mm-62.2 mm, 53,0 mm-65.4 mm and 49.3 mm-68.6 mm, respectively; fruit length were between 45.8 mm-78.5 mm, 54.3 mm-86.7 mm and 52.1 mm-91.1mm, respectively; fruit firmness were between 5.0 kg/cm2-9.8 kg/cm2, 6.8 kg/cm2-13.9 kg/cm2 and 4.8 kg/cm2-8.6 kg/cm, respectively; soluble solid contents were between 10.0 %- 14.4 %, 9.7 %-12.8 % and 11.3% -16.6 %, respectively; titrable acid contents were between 0.69 %-4.38 %, 1.43%- 7.63 % and 2.25%-16.0 %, respectively.

In this study, some pomological characteristics of genotypes previously selected were evaluated by principal component analysis. In the evaluation, it was determined that genotypes originated from Adilcevaz had higher nut weight, kernel weight and oil content, and lower protein ratios. On the other hand, Başçiftlik (Tokat) origin genotypes had lower nut weight, kernel weight and oil content, higher protein ratios. In the most genotypes from Ankara, fruit shape index was determined to be lower (more rounded nut), whereas kernel and nut color values were higher (darker). The genotypes originated from Ermenek were found to have longer shaped fruits, and lighter kernel and nut color. [ABSTRACT FROM AUTHOR]

This study was conducted on 34 walnut genotypes selected as promising as a result of selection study carried out in centre and villages of Tuzluca district, Iğdır. Some measurement and analysis were performed in order to determine some physical and chemical properties of genotypes selected in the study. Nut weight, kernel weight, kernel ratio, and shell thickness of selected genotypes varied in a range of 8.14-13.94 g, 4.01-6.49 g, 34.84- 53.91%, and 1.23-2.46 mm, respectively. For the genotypes, following values were recorded; oil rate as 50.52- 66.68%, protein rate 6.59-26.57%, ash rate 0.98-4.00%, and moisture rate 2.55-6.98%. Contents of N, P, K, Ca, Mg, and Na from macro elements and Fe, Cu, Zn, and Mn from micro elements were determined in walnut samples. Averagely 1.83% N, 335.76 mg 100g-1 P, 493.49 mg 100g-1 K, 260.79 mg 100g-1 Ca, 234.40 mg 100g-1 Mg, 12.71 mg 100g-1 Na, 12.47 mg 100g-1 Fe, 2.88 mg 100g-1 Cu, 2.58 mg 100g-1 Zn, and 3.35 mg 100g-1 Mn were found in genotypes.
