BIOLOGICAL AND PRODUCTIVE PROPERTIES OF THE FORMS OFGRAPEVINE CULTIVAR TRAMINER IN THE SUBREGION OF NIŠ

Traminer is a well-known grapevine cultivar. It is thought tooriginate from Tramin, Italy, wherefrom it has been introduced to many Europeancountries (France, Switzerland, Austria, Germany). Researches included twoTraminer cultivar forms: White Traminer and Red Traminer. Examinations werecarried out in a collection vineyard of the Viticulture and Wine Production Centerof Niš. The collection vineyard was planted in 1995, with planting space of 3 x 1.2m. Examinations took three years (2004-2006) and encompassed phenologicalobservations, fertility, vegetative potential of a vine, resistance to Botrytis cinereaand wine quality. A detailed ampelographic description of two Traminer cultivarforms was also provided according to O.I.V. descriptors. The purpose of this paperis to determine growth, fertility, yield, and grape and wine quality of the examinedTraminer cultivar forms in the viticultural subregion of Niš. According to theresults obtained, the examined forms could be successfully grown in this region.Average grape yield varied depending on conditions of the particular year. WhiteTraminer recorded higher yield, while Red Traminer recorded better quality. Inaddition, the best vines have been selected within the forms, and they will be usedin further studies and multiplication.
