Turkish hazelnut initiative targets drought resistance

The General Directorate of Forestry (OGM) in Turkey is working to integrate the Turkish hazelnut (Corylus colurna L.) into wider production to combat the threats of climate change and increasing drought. Through efforts at the Bolu Nursery, the organization aims to utilize the species in both forest areas and commercial hazelnut cultivation.

Known locally as Seben or Bolu hazelnut, the Turkish hazelnut features a deep taproot system that provides significant resistance to drought and harsh growing conditions. Because it does not produce basal or bottom shoots, it is being considered as an alternative rootstock for commercial hazelnut production under changing climatic conditions.

Specific plans involve grafting important Turkish varieties, such as Çakıldak and Giresun Yağlısı, onto the Turkish hazelnut rootstock. This aims to combine the robust root structure of the native species with the high-yield production characteristics of commercial varieties. Beyond agriculture, the saplings will be used for forest rehabilitation, reforestation, ecological restoration, and landscaping.
