Association mapping and candidate gene identification for yield traits in European hazelnut ( L.).

European hazelnut ( L.) is an important nut crop due to its nutritional benefits, culinary uses, and economic value. Türkiye is the leading producer of hazelnut, followed by Italy and the United States.

GRAS-Di SNP-based molecular characterization and fingerprinting of a Turkish Corylus avellana core set provide insights into the cultivation and breeding of hazelnut in Turkey.

Hazelnut (Corylus avellana L.) is an economically and socially important product for Turkey, the country that leads global production of this crop. The preservation of Turkish hazelnut genetic diversity and informed breeding of new cultivars are crucial for maintaining quality and crop yield stability.
