PERFORMANCE OF ELEVEN HAZELNUT CULTIVARS FROM DIFFERENT COUNTRIES IN TARRAGONA (SPAIN)

During 9 years the performance of eleven cultivars coming from three different countries was evaluated in a comparative trial at IRTA-Mas de Bover, Constantí (Tarragona, northeastern Spain). The own rooted cultivars were: ‘Clon La Masó’, ‘Negret N-9’, ‘Negret Primerenc’ and ‘Pauetet’ (Spain); ‘San Giovanni’, ‘Tonda di Giffoni’, ‘Tonda Italiana’ and ‘Tonda Romana’ (Italy); ‘Clark’, ‘Lewis’ and ‘Villamette’ (USA). The trial was established in 2001; trees were spaced at
6×3.5 m and conducted in a single trunk, with drip irrigation.
The statistical design was a randomized complete block with 11 replications and one tree per replication and treatment.
Production, suckering, tree vigor and nut and kernel characteristics (weight, kernel size >12 mm, and defects) were evaluated. ‘San Giovanni’ (near
40 kg/tree), ‘Tonda Italiana’ (37 kg/tree), ‘Pauetet’ (35 kg/tree) and ‘Clon la Masó’ (34 kg/tree), excelled for their cumulative nut yield, whereas ‘Negret Primerenc’, ‘Tonda Romana’ and ‘Villamette’ were less productive.
Referring to nut characteristics, kernel percentage of ‘Clon La Masó’ and ‘Clark’ cultivars, with values of 51.13 and 50.67%, respectively, were the highest, whereas ‘Tonda Italiana’ presented less kernel yield (38.25%). ‘Tonda di Giffoni’, ‘Clark’ and ‘Tonda Romana’ stood out for their big kernel size (>12 mm).
