The aim of this dissertation was to compare qualitative and quantitative of a Sauvignon clone samples, describe and evaluate particular phenological phases and uvology values, describe and evaluate the analysis of must. The experiment was established in the viticulture Vineyards -- Hnanice. On three variants of Sauvignon clones differences in phenological phases in the same conditions were observed. Subsequently analytical values of must from each clone were evaluated. The sugar content, titratable acids, the pH, the yield per a bush, the weight of 50 berries, the average weight of a bunch of grapes, the average weight of a berry, the yield of grapes per a bush were monitored. The results showed that the Austrian A clone that has been the weakest in a growth, had the highest values, and vice versa French clone F 316 with the most extravagant growth had the lowest values. The results showed that it is advisable to plant more clones with different properties. The results were statistically analyzed and compared with attempts by other authors.
