FEW-YEAR RESULTS OF SOME ITALIAN HAZELNUT CULTIVARS GROWN IN THE REGION OF ČAČAK

The paper presents major biological and pomological properties of some Italian hazelnut cultivars (‘Riccia di Talanico’, ‘Giromelo’, ‘Mortarella’, ‘Tonda di Giffoni’, ‘Tonda Romana’, ‘Tonda Gentile delle Langhe’, ‘Comune’) grown under the environmental conditions of Central Serbia (region of Čačak). Aiming at comparison, ‘Barcelona’ was included in the trial field as a standard cultivar.
Some phenological properties, such as catkin pollination, flower opening and ripening time were assessed, along with vigour, cropping and cropping potential.
Fruit size and weight, shell thickness and kernel ratio were also determined.
The study included the evaluation of chemical composition of kernel, i.e., the content of water, ash, mineral matter, oils and raw proteins. ‘Barcelona’ was classified among the most vigorous ones.
As regards cropping, Italian cultivars were superior to ‘Barcelona’. A greater number of fruits per flower bud were evidenced in Italian cultivars.
Over a long-term period, the average fruit weight ranged from 2.86 g (‘Mortarela’) to 3.34 g (‘Barcelona’), whereas fruit ratio ranged from 42.0% (‘Barcelona’) to 51.02% (‘Riccia di Talanico’). Kernel oil content and raw proteins content were within the range of 58.53% (‘Barcelona’) to 62.17% (‘Tonda Romana’), and from 15.03% (‘Tonda di Giffoni’) to 17.20% (‘Mortarella’) respectively, whereas mineral matter content ranged from 2.42% (‘Tonda Gentile delle Langhe’) to 3.12% (‘Tonda Romana’).
