Agrobiologické vlastnosti klonů révy vinné

This work is about clonal selection and comparison of clones which are maintained by grapevine breeding company in Boršice. In the start of the work we clarify meaning of words clone and clonal selection. Then we talk about history of clonal selection, certi-fication scheme and somatic mutations, which are cause of changes in plants. Next part is about genetic correlations, especially about genotype by environment interaction and interaction between traits of grapevine. Theoretical part ends with explanation of phyto-sanitary care of grapevine and about methods which should ease clonal selection. In practical part of this work we compare Czech and foreigner clones of Gewürz-traminer. We also talk about environment and form of vineyard management and used measuring methods. Then this work shows graphs and results of the experiment. The grapevine clone PO 202/A had best result in this experiment. In the end this work talks about recommendation for future of clonal selection
