Hodnocení výskytu houbových chorob u tritikale a jejich vliv na výnos
Petříková, Markéta
The bachelor thesis focuses on the occurrence of fungal diseases in two variants of the treat-ment of winter triticale. The first variant was with fungicidal treatment and the second variant without. The experiment was performed on the Field research station of Mendel University in Žabčice. Five varieties in four replications in each variant were evaluated. The work compares the occurrence of fungal diseases, the number of grains in spike, the number of spikes per m2, the thousand seed weight and the yield in both variants. Pathogens of Blumeria graminis and mild occurrence of Puccinia striiformis were found. The average yield of untreated variant was 6,3 t.ha-1 and in treated variant was 5,8 t.ha-1 As a result of drought, the treated variant was damaged, so the values were lower than in the untreated variant.

Hodnocení napadení vybraných odrůd tritikale houbovými patogeny v polních podmínách
Olšanský, Jiří
The bachelor thesis presents results of small-scale experiments with winter triticale on the grounds of Mendel University in Žabčice. Triticale was sown in two variants. One variant was with application of fungicide and the other without. A total of 6 varieties were tested with 3 repetitions. The work compares the fungal pathogen attack on both variants and evaluates other parameters such as yield, 1000 seed weight, plant height, ears per m2, number of grains in the spike and weather conditions. Due to insufficient precipitation, fungal pathogens had poor conditions to spread and yield has been greatly reduced. Untreated variants were slightly infected with Powdery mildew and leaf blights.

Rye and triticale growing in Czech Republic
MACHNÍK, Jiří
The aim of the bachelor thesis is to summarize the knowledge about cultivation of the rye and triticale in the Czech Republic. A partial goal was to summarize the knowledge about the use of life and tritical and the suitability for sustained management systems.

Možnosti použití žita a dalších obilovin pro surogaci při výrobě piva
Žák, Jiří
Bachelor's thesis Possibilities of rye and other cereal grains use as brewing adjuncts focuses on minority cereals and their properties relevant for brewing industry, with special regard to rye (Secale cereale) and triticale (× Triticosecale). As available studies suggest, triticale seems to be a promising material to be used in larger quantities as a source of starch, or to complement nitrogen and enzyme poor adjuncts. Rye, on the other hand, is a rather troublesome grain and offers little advantages for an extensive use. Nevertheless, it can be a valuable material for specialty beer production, due to its capability to impart specific flavours. With regard to gluten-free beer production, further attention should be paid to rarely used millets, especilally teff (Eragrostis tef).

The cereals growing in ecological farming system
VESELÝ, Tomáš
In this work were compared differences between organic, transitional and conventional farming systems. Grain yields were compared, the amount of agricultural engineering and economics in a selected company Farma Otročín Ltd. In the years 2007-2014.

Studium polymorfizmu DNA u tritikale
Svojsíková, Nikola
Recently known varieties of triticale do not meet milling and baking requirements. The reason is a presence of chromosome R in triticale, which decreases viscoelastic qualities of dough, and a presence of secalins, which decreases technological qualities of grain. Bachelor thesis devotes to detection of high-molecular-weight glutenin subunits (HMW-GS) and low-molecular-weight glutenin subunits (LMW-GS). In total there were 14 genotypes of triticale analyzed in the thesis. DNA markers based on polymerase chain reaction (PCR) were used to identify allelic combinations in loci Glu-A1, Glu-B1 and Glu-D1, which encode high-molecular-weight glutenin subunits, and secalin locus. Alleles Glu-A1a, Glu-A1b, Glu-A1c were detected in locus Glu-A1. Four allelic combinations of glutenin subunits Bx7+By18*, Bx7*+By8, Bx7+By8*, Bx7+By8 were detected in locus Glu-B1. Allele Glu-D1d was detected at two breeding lines. Sec-1 was detected at 12 breeding lines. DNA markers were used to discover allelic composition of locus Glu-A3, which encodes low-molecular-weight glutenin subunits. Alleles Glu-A3a, Glu-A3d and Glu-A3f were not detected at analyzed breeding lines at all.

Biodiversity of model agroecosystems on the ecological farm in the foothills of Šumava Mts.
OUŘEDNÍK, David
The content of the thesis was research and study of the epigeal beetle communities at three different sites in the cadastral municipality Mačice near village Soběšice in Western Region. Habitats were managed under organic farming. Specifically there were three different sites, a field sown triticale, meadow and pasture. Method of pitfall traps was used for the collection of biological material. In total, there were intercepted and identified 640 individuals from 57 species and 14 families in the reporting period. In all of the habitats, species of beetles family (Carabidae) (23 species) were mostly represented, followed by family rove beetles (Staphylinidae) (11 species) and family carrion (Silphidae) (6 species). Most individuals were found at the field habitat with the numbers in total of 255 (30 species from 8 families), followed by habitat meadow with 198 individuals (36 species from 9 families) and the pasture habitat with 187 individuals (34 species from 10 families). The species spectrum of epigeal beetles was divided into groups according to the sensitivity to anthropogenic influences. Species that do not have special requirements on the quality and nature of the environment (group E) dominated in all habitats with 48 species. Total of nine species inhabiting habitats moderately affected by human activities (group R2) were found in all habitats, the least of them occurred in the field (1 species) , pasture (5 species) and at the meadow were found most (6 species). Index of anthropogenic impacts shows that these are very heavily modified habitats. When comparing individual sites, field habitat (ISD 1,67 %) was found to be the most affected. The least affected was the meadow habitat (ISD 8,34 %). As a result we can conclude that the hypothesis that organic farming has a positive impact on biodiversity was not confirmed.

Qualitative parameters of triticale grains
PLÁNSKÁ, Vlasta
Triticale is a hybrid of rye and wheat. After both parents got good features. It is tolerant to worse conditions than wheat cultivation and has good health. Master thesis , Qualitative properties of grain triticale '' presents a comparison of the yield and quality evaluation of basic parameters of grain triticale. Among the selected quality parameters were included in the weight of a thousand grains, moisture , density and chemical composition of the grains. In 2010 and 2011 he was at the experimental plot Faculty of Agriculture, University of South Bohemia based varietal tests . Was grown and monitored 13 varieties of triticale. Based on the results of the thesis yielded the following conclusions. The values recorded for most varieties suggest the possibility of a potential for the breeding area of bakers use. The varieties showed lower gluten content and lower results in Zeleny test. The varieties have low values protein fraction and N-compounds. To improve the feeding value would increase the recommended dose of nitrogen fertilization. For the milling using these varieties are not suitable because of lower bulk density. Relatively good application would find these varieties in the use of bioethanol as a lower protein content means higher starch content. The results showed that triticale is more appropraite Grain other more intensive cultivation.
