Assessment of genetic diversity revealed by morphological traits and ISSR markers in hazelnut germplasm (Corylus avellana L.) from Eastern Black Sea Region, Turkey

Turkey is one of the most important centers of origin for hazelnuts as well as many fruit species. The Black Sea Region of Turkey, where hazelnut cultivation has been carried out for centuries, is very rich in hazelnut genetic resources. This study aims to assess phenotypic variation in nut traits and genetic diversity revealed by inter simple sequences repeat (ISSR) markers in hazelnut germplasm resources from the Eastern Black Sea Region. The nine local hazelnut accessions had a range of 1.68 g to 2.92 g for nut weight, 0.92 g to 1.44 g for kernel weight and 49.3% to 61.7% for kernel percentage. Principle component analysis (PCA) revealed that nut traits could effectively explain the variability among hazelnut germplasm resources. Molecular marker analysis yielded a total of 80 bands, 74 of which were polymorphic, from 9 inter simple sequence repeat primers. The rate of polymorphism varied between 66.7% and 100.0%. Similarity index of hazelnut cultivars and accessions was computed between 0.46 and 0.88. Research findings may contribute to the conservation and maintaining of hazelnut genetic resources. The present study suggests that the accession H-1 with superior nut traits could be good genetic material for the development of new cultivars in future hazelnut breeding efforts

Sugar Contents of Juniper Plants

The contents of free sugar has been confirmed inside the fresh foliage and berry samples gathered from the tree types which are naturally growing in different locations of the province Van and from the tall juniper which is one of the types of Turkish frost trees. It is determined that the average fructose content inside the fresh needle foliage is 44.0-70.2 mg/100 g, average sucrose is 10.0-25.0 mg/100 g, average glucose 22.0-26.0 mg/100 g and average di-glucose (maltoz) content is 5.0-17.0 mg/100 g. It has been found that the free sugar content of berry is higher than the sugar content of foliage, except di-glucose

Assessment of Fatty Acid Composition, Bioactive Compounds, and Mineral Composition in Hazelnut Genetic Resources: Implications for Nutritional Value and Breeding Programs

This study was carried out to determine the fatty acid composition, bioactive compounds, and mineral element content of standard hazelnut cultivars and accessions from the Eastern Black Sea region. A wide variation was determined in terms of the traits examined between hazelnut accessions and cultivars. Most of the accessions investigated had higher values of bioactive compounds, oleic acid, stearic acid, Na, and Ca than the standard cultivars. Among accessions investigated, S-1 had the highest total phenolics and antioxidants (557.3 mg/100 g and 0.53 mmol/100 g) while P-4 had the lowest (307.3 mg/100 g and 0.22 mmol/100 g). The highest oleic acid content was determined in P-2 (87.16%); the lowest was in H-1 (71.24%). Linoleic acid ranged from 4.35% (P-1) to 18.06% (H-1). P-2 (3349 mg/kg and 2464 mg/kg, respectively) had the highest K and P contents. The highest Mg content was found in S-1 (1787 mg/kg). The highest value of Ca and Na was determined in P-1 (2701 mg/kg and 412 mg/kg, respectively). Principal component analysis revealed that the traits studied could effectively explain the variability among hazelnut genetic sources. First, three components explained about 60% of total variation. PC1 was related to arachidonic acid and most of the mineral elements (P, K, Mg, Ca, Fe, Mn, Zn, Cu, B, Cd, Ni, and S), and explained 27.6% of the total variation. PC2 explained 18.3% of the total variation, and was mainly related to oleic, linoleic, and linolenic acid, as well as Ca. PC3 was related to total phenolics, total flavonoids, antioxidant activity, and palmitic acid, and explained 14.5% of total variation. The oleic acid had a strong negative correlation with linoleic acid (−0.99 ***) and linolenic acid (−0.95 ***). A strong positive correlation was determined between antioxidant activity and total flavonoids (r = 0.95 ***). K content showed a strong positive correlation with P (r = 0.92 ***) and Mg (r = 0.82 ***) contents. A strong positive correlation was also determined between P and Mg (r = 0.91***). These findings revealed that many of the accessions investigated were a good source of fatty acids and bioactive compounds. As a conclusion, most accessions with superior nutritional content can be evaluated as genetic material for the development of new cultivars in hazelnut breeding programs
