Woody materials, such as this plant, root best from cuttings taken in autumn, treated with #3 rooting hormone and put in the ground outside. tical plants in one year. Turkey is the largest hazelnut producing country with 68% of the world's production, followed by Italy (14%), United States (3.8%), Azerbaijan (3.3%) and Spain (2.6%) (Fideghelli and De Salvador, 2009). Production of nursery plants of the hazelnut cultivars Tonda Gentile Romana , Istarski dugi , Halls Giant, Cosford , Redleaf Lambert and Contorta , grafted by the method of English grafting on the Turkish hazelnut (Corylus colurna L.) was tested in the period from 2005 to 2007. The purpose of this project was to develop a more cost effective, efficient and sustainable method of propagating new hazelnut cultivars. Propa-gation by rooting of softwood and hardwood cuttings is a simple, rapid and cost-effective method (Hartmann & Kester, 1968) but it is very seldom used for hazelnut (Wu, 2013). The 1st experiment in Objective 2 is designed to evaluate the hardwood stem cutting technique for the propagation of hazelnut accessions. by Dawn and Jeff Zarnowski. In the plant world, the contorted filbert (Corylus avellana "Contorta") is the opposite of the ugly duckling. Hazelnut seeds do not produce similar trees to the mother plant, and the hazelnut should be propagated vegetatively and clonally.
