Modern climate changes task breeders to adapt viticulture to the new natural resource potential of the regions. A necessary condition is the assessment and analysis of current trends in changing the characteristics of contrasting groups of varieties. The aim of the study is to identify homogeneous groups of varieties of an ampelographic collection and to compare the rates of reaction of their agrobiological parameters to climate changes. Material for the study consists of observations of 21 agro
