This paper reviews the results of a morphometric analysis of fruits of selected genotypes of Turkish hazelnut, seed germination, and grafting success of seedlings of the analyzed genotypes. The obtained data indicated highly significant positive direct effects of fruit width and nut kernel recovery on seed germination rate, as well as highly significant negative effect of pericarp thickness. The hazelnut genotypes selected at the location Futoški Park (B1, B4, B5, B7, B8 and B9) have shown high seed germination rates in the test years and they formed thick canopies in the rows. Main reasons for the high germination rates were favourable ecological conditions at the time of seed production and germination assessment, as well as successful rodent protection in the nursery. The genotypes were grafted in early April of 2007. High grafting was applied in order to produce hazelnut trees. The whip and tongue grafting technique was used because it provides a firm union between the rootstock and the scion. At the end of vegetation period, the grafting success ranged from 69.30% (Corylus avellana f. atropurpurea) to 98.79% (Rimski) which indicated a high affinity between the rootstocks and the scions.
