Abstract:Hmelj (Humulus lupulus L.) je trajnica, ovijalka in dvodomna rastlinska vrsta, kar pomeni, da na eni rastlini najdemo le moške ali le ženske cvetove. Ženska socvetja, storžki so zaradi specifične kemijske sestave nepogrešljivi v pivovarski industriji. Moške rastline uporabljajo le pri žlahtnjenju. V diplomskem delu je prikazan del žlahtniteljskega programa Inštituta za hmeljarstvo in pivovarstvo Slovenije oz. selekcija sejančkov hmelja s povečano odpornostjo na hmeljevo pepelovko (Podosphaera macularis) in hmeljevo peronosporo (Pseudoperonospora humuli) v rastlinjaku iz 2004, 2006, 2008, 2009, 2010, 2014, 2016 in 2018. V statistično raziskavo je bilo vključenih 140.877 sejančkov, potomcev več kot 1000 različnih kombinacij križanj. Moški genotipi so ključnega pomena za doseganje zadovoljivega števila potomcev in zaželene stopnje odpornosti preživelih sejančkov. Križanja kultiviranih ženskih komponent z divjimi moškimi genotipi so, v primerjavi s kultiviranimi moškimi genotipi, manj perspektivna. Raziskava kaže, da je stopnja odpornosti na omenjeni bolezni odvisna od obeh starševskih komponent: materne in očetne. V raziskavi smo izpostavili tudi nekaj superiornih maternih in očetnih komponent ter 55 najboljših kombinacij križanj, kar bi lahko predstavljalo zelo koristno in praktično informacijo za nadaljnje načrtovanje križanj hmelja s ciljem oblikovanja odpornih sort na hmeljevo pepelovko in hmeljevo peronosporo.

Title:Resistance of Hop seedlings to Powdery mildew and Downy mildew based on the Selection of Perspective Parental Hybrid Combinations
Abstract:Hop (Humulus lupulus L.) is a perennial, climbing, dioecious plant species, meaning that male and female blossoms are found on separate plants. Female inflorescences (cones) are, because of their specific chemical composition, indispensable in the brewing industry. Male plants are used only for breeding purposes. In the thesis, a part of a breeding programme at the Slovenian Institute of Hop Reseach and Brewing is presented, namely the selection of hop seedlings in a greenhouse associated with testing the resistance to powdery mildew (Podosphaera macularis) and downy mildew (Pseudoperonospora humuli) in the years 2004, 2006, 2008, 2009, 2010, 2014, 2016 and 2018. In the statistical evaluation, 140.877 hop seedlings were included: the offspring individuals derived from more than 1000 different crosses. The male genotypes are crucial for achieving a satisfactory number of offspring genotypes and a desired level of resistance, enabling the survival of seedlings. Crossings of cultivated female components with wild male genotypes are less perspective when compared to the cultivated male genotypes. The research shows that the degree of resistance to the aforementioned diseases depends on both parental components: maternal and paternal. As a result of the research, some superior female and male parental genotypes were exposed, together with 55 most promising hybrid combinations, which could be highly valuable information for further practical work associated with the developing of new hop varieties resistant to powdery and downy mildews.
