The olive tree is the most widely spread throughout the Mediterranean and is imprinted in the mythology and history of many countries. The olive is a subtropical evergreen plant, up to 15 meters high and belongs to the family of the same name (Oleacea). Grafting is one of the vegetative methods of propagation, by combining different substrates and varieties, under different agroecological conditions. The aim of this study was to monitor vegetative growth of breeds of varieties 'Istarska Bjelica', 'Krvavica', 'Leccino', Picholine', 'Pendolina' for the rootstock of the variety 'Oblica'. The vegetative parameters that were monitored were average number of shoots, number of leaves, number and length of shoots. On receipt of total average broods for the rootstock, the highest success was shown by the variety 'Picholine'. at 68%. The 'Pendolino' variety proved to be the leading variety by the average number of leaves 170.8 per shouts, length of shoots 75.3 cm and number of shoots 1.7 per brood. Far belowaverage results were shown by the variety 'Krvavica', with 36% of seedlings received, 70.8 leaves, 33.1 cm length of shoots and 0.9 shoots per brood. The varieties 'Istarska Bjelica' and 'Leccina' showed average results in the categories followed. The purpose of this work is to gather information on vegetative parameters (compatibility) of grafted varieties for the 'Oblica' substrate.
