Comparison of Aletta and Bianca grape varieties in Hungary
LIn recent years there has been an increasing interest in growing grapes in ecologically friendly and organic viticulture. The Research Station of Viticulture and Enology in Eger has introduced several interspecific cultivars free from an undesired off flavour by crossing American Vitis species with traditional European Vitis vinifera. This cultivar is the result of crossing Muscat Ottonel with Seyve-Villard 12375. In this paper a new resistant hybrid, âAlettaâ was evaluated during the registration process. The evaluation was performed within the period of 2005-2009 in several production sites in Hungary. âAlettaâ was compared to âBiancaâ cultivar. âAlettaâ showed about 50% more yield but was distinguished by lower sugar content. Wine acidity was not significantly different from âBiancaâ. In sensory evaluation âAlettaâ achieved better scores. The wine had harmonious acid composition and muscat flavour. Vine is vigorous but spur pruning is recommended because of the big cluster weight and high bud fertility. The intemodes are long and the canopy is loose that results an easier canopy management. Since âAlettaâ was registered in 2009 its vineyard surface has reached 1300 hectares in Hungary

ĂsszefoglalĂĄs: Az utĂłbbi Ă©vtizedekben felĂ©rtĂ©kelĆdött az organikus növĂ©nytermesztĂ©si szemlĂ©let. A SzĆlĂ©szeti Ă©s BorĂĄszati KutatĂł IntĂ©zet Egri ĂllomĂĄsĂĄn több olyan bor- Ă©s csemegeszĆlĆ fajtĂĄt ĂĄllĂtottak elĆ, melyek labruscaĂz mentesek, jĂł lombrezisztenciĂĄval rendelkeznek. Az Aletta szĆlĆfajtĂĄt a Muscat Ottonel Ă©s Seyve-Villard 12375 fajtĂĄk keresztezĂ©sĂ©vel ĂĄllĂtottĂĄk elĆ. A fajta minĆsĂtĂ©si folyamatĂĄban a Bianca fajtĂĄval hasonlĂtottĂĄk össze. Az Aletta termĂ©s mennyisĂ©ge csaknem kĂ©tszerese a BiancĂĄnĂĄl, mely a nagyobb rĂŒgytermĂ©kenysĂ©gnek Ă©s nagyobb fĂŒrttömegnek köszönhetĆ. Mustfoka alul marad a Bianca fajtĂĄnak, viszont bora illatosabb Ă©s harmonikusabb. TökĂ©je erĆteljes növekedĂ©sƱ, lombszerkezete kedvezĆ a gyengĂ©n fejlĆdĆ hĂłnaljhajtĂĄsok miatt. Mivel alsĂł rĂŒgyei is termĂ©kenyek, rövid csapos metszĂ©s szĂŒksĂ©ges. Nagyobb terhelĂ©s mellett a termĂ©sĂĄtlaga elĂ©ri a 15-20 tonnĂĄt hektĂĄronkĂ©nt. Az alacsony szĆlĆ felvĂĄsĂĄrlĂĄsi ĂĄrak miatt a termelĆk törekednek a minĂ©l nagyobb termĂ©s elĂ©rĂ©sĂ©re. SzĆlĆjĂ©bĆl asztali bor kĂ©szĂŒl, ezĂ©rt a minĆsĂ©g romlĂĄsa kevĂ©sbĂ© fontos. Az Aletta fajta termesztĂ©se biztonsĂĄgos jĂł fagy, peronoszpĂłra- Ă©s rothadĂĄstƱrĆ kĂ©pessĂ©ge miatt. JĂłl illeszkedik az alacsony önköltsĂ©g-stratĂ©giĂĄjĂș alföldi szĆlĆtermesztĂ©s stratĂ©giĂĄba
