Interspecific varieties of grapevine and their utilization in the breeding
VOCÍLKA, Radek
In the thesis new interspecific varieties, which are in acknowledge-proceeding, have been observed. These varieties are Marlen, Cerason, Kofranka and Kaberon. These were cultivated from commonly used European varieties (Frankovka, Svatovavřinecké, Merlot) registrated in the State Book of Varieties of the Czech Republic. Moreover, during the cultivation blue variety called Seibel was used. This served as a donor of fungicidal desease resistance, or rather tollerance. The varieties were observed for three years and their morphological and degree qualities were investigated. The goal of the thesis was acknowledgement of these interspecific vine varieties, their registration in the State Book of Varieties and later legal protection. The task was to pass diversity, uniformity and stability tests in the proceeding and compare the new varieties with the acknowledged ones, which were used for cultivation.

Hodnocení pěstitelských vlastností odrůdy Solaris v nevinařských podmínkách
Tryzna, Pavel
This diploma thesis deals with cultivation of grape wine varieties in unusual vineyard location. The advantage of PIWI varieties of grape wine are benefitial for this purpose. Grape wine varieties from Czech Republic wine-growing subregions and from northeastern non-wine growing region are examined in this methodology. The research compares analytical values of wines and processes them into graphs and tables. Based on results of this thesis there is a disccussion about whether it is worth to grow grapevine variety ‘Solaris‘ in the above mentioned conditions. The result shows that cultivation of this grapevine variety in the non-wine growing location gives valuable material from which it is possible to make competitive wine product.

Porovnání anthokyanů u modrých odrůd
Smítková, Martina
This thesis deals with the comparison of anthocyanins in blue grape varieties. It has been compared 23 varieties of Vitis vinifera L. and 9 interspecific varieties from the harvest 2015. The grapes come from the wine region Mikulov and from the wine village Lednice. Literary part deals with the chemical structure of anthocyanins and their occurrence in grapes, further accumulation of anthocyanins and influencing factors, physico-chemical factors affecting the stability of anthocyanins, change of anthocyanins during the vinification and extraction of anthocyanins and measurement of color parameters. The practical part is especially focused on compare the content of anthocyanins and their profile in varieties of Vitis vinifera L. and interspecific varieties.
