- New hazelnut cultivars introduced from the Hazelnut Breeding Program at Oregon State University (Corvallis), and commercially grown cultivars were evaluated from 2007 to 2011 at Santa Rosa, Experimental Farm at Centro Regional de InvestigaciÃ³n Quilamapu, Instituto de Investigaciones Agropecuarias (latitude 36Â°31â34âS; longitude 71Â°54â40âW), Chillan, Chile. Plantings established in 2005 and 2007 are discussed in this paper. The 2005 trial were ten cultivars; âMontebelloâ, âWillametteâ, âLewisâ, âMortarellaâ, âButlerâ, âCasinaâ, âEnnisâ, âHallâs Giantâ, âNegretâ, âTonda delle Langheâ. During the first years of evaluation, the cultivars; âEnnisâ, âMortarellaâ, âButlerâ, âMontebelloâ and âWillametteâ had cumulative nut production greater than âHallâs Giantâ, âNegretâ and âTonda delle Langheâ, which had the lowest cumulative nut production. The yield efficiency of the cultivar âCasinaâ was the highest (54.8%), while âMontebelloâ was the lowest (33.35%). The cultivars âEnnisâ, âLewisâ, âCasinaâ and âMortarellaâ exhibited the lowest percentages of blanks (0, 1, 2 and 4% respectively), while the cultivars âMontebelloâ, âButlerâ, âHallâs Giantâ and âWillametteâ, presented 18, 13, 11 and 11% respectively. Kernel weight of the cultivar âEnnisâ was 2,14 g, while âMontebelloâ and âCasinaâ were 1.0 g each. The cultivar âLewisâ had a kernel weight of 1.4 g. The 2008 trial included âSan Giovanniâ, âGemâ, âEpsilonâ, âEnnisâ, âZetaâ, âClarkâ, âLewisâ, âDeltaâ, âPauetetâ, âMortarellaâ, âRibetâ, âGhiraraâ, âIanussa Racinaâ, OSU 540.130 and âSantiamâ. âSan Giovanniâ had the highest production (1 kg/plant) and âEpsilonâ, âGemâ, âMortarellaâ, âLewisâ, âPauetetâ and âRibetâ had 0.5 kg/plant by the four leaf.
