<div><p>This study was carried out during 2002-2005 in the Regional Centre of Scientific Applied Service in Kardjali, Bulgaria. Two-year seedlings of <em>Corylus colurna</em> L. forms 21/7 and 29/5 were used as rootstocks and Halsky and Almond's filbert varieties as grafts. The grafting processes were performed through chip budding in spring and in summer. The following conclusions can be drawn as results of this study: the Turkish hazel rootstocks of forms 21/7 and 29/5 are highly vigorous and they have comparatively even sizes in the seedling plot. Grafting in spring is a perspective graft method for the variety-rootstock combination of Turkish hazel form 29/5 and Halsky variety. A large number of standard trees (4767) which was obtained from one decare in the nursery showed that the variety-rootstock combination consisting of hazel form 29/5 and Halsky variety was the optimum one and it could be applied in practice. The seedlings' features of form 21/7 induce further research work extension including other combinations with grafts of new varieties.</p></div>
