Aim of this thesis was to answer question how big is influence of geological and pedological conditions on qualitative parameters of wines. Four sites with variety Ryzlink rýnský have been choosen on vineyard Velká Vendule in Velké Žernoseky based on differect pedological a geological characteristics. Site have been closely described from pedological point of view. Wine samples from vintages 2012 to 2014 have been made from every site via unified vinification so 51 wine properities could be measured. Results have undergone canonical diskriminant analysis. It was found content of elements in soil isn't in clear relation to content in wine, mainly because different climatic conditions each year. In spite of this it was possible to clearly separate all wine samples by sites by chossing selected parameters (D/H)II, 13C, B, Ca, K, Mg, P, catechin a trans-piceid. They could be therefore called markers for tracking wine authenticity in relation to geological and pedological conditions.
