“…Twenty-seven trees, out of 244, are estimated at 1, there is no pellicle intrusion. The same quality can be ascribed to the fruits of five selected types from Sinop vicinity in Turkey (Serdar 1999). Serdar and Soylu (1999) report about five trees from the area of Samsun vicinity which lack the pellicle intrusion, one tree exhibits 1 mm penetration of episperm into the embryo, and in another type the intrusion is 1-3 mm.…”

“…The two colours that also appear but are rarer are light brown and reddish brown (Botu et al 1999). Serdar (1999) and Serdar and Soylu (1999) report that the local types from Sinop and Samsun vicinities in Turkey have only brown or smoothly dark brown fruits.…”

“…Similar conclusions have been reached by certain authors who have been researching phenotypic diversity among various local populations of European chestnut in Italy (Borghetti et al 1986;Casini et al 1993; Ponchia et al 1993a, b;Jacoboni 1993), in France (Breisch et al 1995), in Portugal (Gomez Pereira et al 1993), in Spain (Pereira Lorenzo et al 1996a;Pereira Lorenzo and Fernandez Lopez 1997), in Greece (Zakynthinos and Lionakis 1997), in Turkey (Ayfer and Soylu 1993;Serdar 1999;Serdar and Soylu 1999) and in Romania (Botu et al 1999). This research forms basis for the selection of the best types from natural populations where domestic chestnut has been produced for centuries, and this, according to Bounous et al (1993), is essential in order to intensify the production of European chestnut.…”

Phenotypic diversity of 244 chestnut trees was investigated. They originate from the Mediterranean and from two continental regions in Slovenia. In 3 years of analyses, length, diameter, thickness and weight of fruits; length and width of hilum, the pellicle intrusion; shape and colour of fruits; and the embryony were dealt with. The continental trees have smaller fruits than the Mediterranean trees; their fruits show greater variability in shape and the pellicle intrusion is stronger. They also exhibit polyembriony more frequently and they rarely have darker stripes. The sample of 46 trees from all three regions was used for the comparison between the phenotypic and genotypic diversity which had been investigated by RAPD analysis. In both cases, the UPGMA method was used for the classification of the trees into groups. Six pomological clusters were established. The clusters I, II, III and V comprise only the trees from the continental part. The cluster IV comprises nine trees of the marron type from the Mediterranean and one KOZ1 tree with equal pomological characteristics but originating from the continental part. The cluster VI is composed of eight trees from the continental part and one RAV3 tree whose fruits are very small and it originates from the Mediterranean. The Jaccard's coefficient of similarity is used in order to evaluate genetic relations. On the RAPD dendrogram four clusters of trees are defined. The continental trees are divided into three clusters and exhibit greater genotypic diversity than the Mediterranean trees which form only one cluster. With the RAPD analyses the differentiation of the trees with regard to their pomological traits is determined in 60-90% of the cases. The outcome of the research point to the fact that the Slovene chestnut is a rich source of genetic diversity and is very suitable for further breeding purposes.

“…Ertan et al (2007) reported nut weight of 5 selected European chestnut genotypes higher than 15 g in Aegean region in Turkey. Serdar and Bilgener (1995) found nut weight of selected chestnut genotypes in Samsun and Sinop province (Black Sea Region in Turkey) varied from 11.7 to 15.1 g and 9.97 to 10.10 g. Serdar (2002) selected 13 new chestnut genotypes in Camili vicinity of Northeastern part of Turkey and average nut weight and kernel weight varied between 4.79 to 7.45 and 4.04 to 6.13 g respectively. In our study, the genotype IY42 found the most promising for earliness and nut weight (6.62 g) indicate higher nut weight than previously selected early-fruiting chestnut selections in Turkey (Ayfer and Soylu 1995;Akca and Yilmaz 1999).…”

Turkey ranked third place in the world for chestnut production after China and South Korea and the country has unique chestnut forests including valuable and diverse chestnut genotypes. This study was conducted to select superior chestnut genotypes within seedling populations found in natural wild grown chestnut forest located in Isparta province in Turkey during 2010-2011 years. A total of 2500 wild grown chestnut trees were examined on the field first year and among them the most promising 22 genotypes were chosen according to relatively high yield capacity, earliness, tolerance to chestnut blight (Cryphonectria parasitica), ink disease (Phytopthora cambivora), and fruit quality characteristics. The selected 22 genotypes were evaluated for their detailed morphological, phenological and pomological traits in 2010 and 2011. According to average of 2 years, nut weight, the number of nut per kilogram, nut width, nut length, nut height and nut shell thickness of 22 promising genotypes ranged from 10.26 to 22.32 g, 97.47 to 44.80/kg, 26.80 to 42.47, 16.92 to 25.91, 27.74 to 39.73, and 0.26 to 1.01 mm, respectively. The ash, crude protein, and total fat content of kernels were between 0.85 to 1.94, 3.69 to 7.06 and 1.32 to 4.52, respectively. The genotypes were evaluated with weighted ranking method and the highest general quality score was observed in genotypes of IY17, IY01, IY42, IY43 and IY12.

“…Anatolia is one of the places chestnuts originated and were first cultivated (Soylu, 2004). The first scientific selection studies on the chestnut started in 1975 in the Marmara region, while other regions later followed with selection studies at different institutes (Ayfer et al, 1977;Ozkarakas et al, 1995;Serdar, 1999;Serdar and Soylu, 1999;Serdar, 2002;Ertan et al, 2007;Koyuncu et al, 2008). Some isozyme studies on the European chestnut indicate that Turkey has a range of potential of chestnut genotypes and is considered to have different subspecies of C. sativa Mill.…”

:Here we report phenotypic and genotypic differences among 14 Turkish chestnut genotypes. The genotypes were analyzed both genetically and for 30 morphological criteria comprising 12 qualitative and 18 quantitative characteristics. The phylogenetic relationships were determined between different chestnut genotypes selected from Sinop, Samsun, Artvin and Bartin provinces of Black Sea Region in Turkey. Morphological criteria were investigated biometrically using multivariate analysis. Ten morphological criteria were found to be effective for discrimination between the genotypes. Five morphological criteria accounts for 64.1% of the variability. These morphological criteria were the ratio of length of teeth to width of teeth, the ratio of length of hilum to length of fruit, cross section of leaves, the ratio of height of fruit to length of fruit and peeling of testa. The discrimination of morphological criteria was shown using cluster analysis, which created four main groups. Dice's coefficient was used to evaluate the genetic similarity by RAPD analysis, which created three main groups. The UPGMA method was used for the determination of phylogenetic trees. The genetic and morphological dendrograms were compared using the Mantel test, which gave a correlation of r=-0.33.

This study illustrates that the selected chestnut genotypes might be valuable genetic resources for future chestnut breeding programs.
