The quality of wheat grain
VOKATÁ, Lucie
The main objective thesis was consider resistence of grow grain as elementary qualitative parameter food wheat by selection variety winter wheat. The test was create in vegetational period of years 2014/2015 on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. In total was for test select 9 variety winter wheat. All variety had show high value number fall, high resistence against grow grain, which ranged 376 to 512 s. In evaluation observe variety suitability in terms of baking, we can say elite (E) inbreads reached the highest average number values fall (479 s). Quality (A) varietes showed value (453 s) and bread (B) varieties reached the lowest value (435 s). The partial objective was evaluation and other indicators (Zeleny test, The content of N-substances and density). Value of Zeleny test ranged 35 to 53 ml., from it averaged of all varietes 49,4 ml. The content of N-substances varied for each variety in 14,23 % - 16,52 %. Most of the studied varieties meet the standard set limit density (760 g/l-1). Ranged from 747 to 819 g/l-1. During the vegetation was also evaluated the health status of vegetation and there has been a determination of ears per square meter. After harvesting, they were also evaluated as further yield elements (number of grains per spike and HTZ). The experiment was evaluated by a high level of quality indicators, where individual varieties also showed high rebenues. This may be primarily affected by higher than average temperatures during the period of years 2014/2015, agrotechnics, but but also the level of nutrition and fertilization of crops.

Evaluation of grain yield components in selected winter wheat cultivars
ZELINKOVÁ, Monika
This thesis deals with the yield ability of chosen winter wheat varieties during growing season 2014/2015. Comparison of the two varieties (hybrid and linear). The experiment was established in standard and reduced seed rates and also in four replicates on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. Were examined yield components: the amount of spikes per 1 m2, amount of grains per spike and weight of thousand grains. During the vegetation observed were the amount of plants per 1 m2, each growth phase, the number of stalks per 1 m2 and plant height. Furthermore, measured were amounts of units of chlorophyll in plants using device N-Tester and the SunScan device sunlight usable for photosynthesis of plants wherein the processed values of leaf area index (LAI). At the end, compared were the theoretical and real yield and evaluated were spike length, amount of spikelets in spike and density.

Hodnocení potenciálních donorů vyšší odolnosti k suchu u pšenice ozimé
Prokešová, Lenka
This work summarises the results of experiments with common wheat lines (T. aestivum L. emed. Fiori et Paol.) during the growing season 2013/2014. Field experiments were carried out in two locations -- Žabčice and Branišovice. Two winter wheat varieties (Etela and Meritto) commonly cultivated in the Czech Republic and 45 Syrian lines with potentially high drought tolerance were evaluated in this work as well as Syrian variety CHAM 6. Spikes analyses were performed and the evaluated characters included awn length, spike length, spike weight, spikelet number, rachis length, rachis segments number, grains per spike number, and grains per spike weight. We focused also on grain yield per plant and the weight of thousand grains. The effect of location was highly significant for both characters -- yield per plant was higher in Žabčice, thousand grain weight in Branišovice. Two quality indicators were assessed -- the content of proteins and starch. As to protein content, all lines and control varieties exceeded the standard given in ČSN 461100-2. The amount of starch was between 66 and 68 %. The response to day length was characterised according to the photoperiod loci Ppd-D1. Photoperiod insensitive allele Ppd-D1a was more common in lines of Syrian origin than sensitive allele Ppd-D1b. To evaluate the tolerance to drought the osmotic potential was determinated and the greatest ability of osmotic adjustment was found in line 27/1.

Yield formation of winter wheat
ŠEVČÍKOVÁ, Tereza
This thesis deals with yield formation with the 12 varieties of winter wheat during growing season 2013/2014. The experiment was established in four repetitions on the plot of Faculty of Agriculture, University of South Bohemia in České Budějovice. Examined yield components were the amount of spikes per 1 m2, amount of grains per spike and weight of thousand grains. Furthermore evaluated were the amount of plants per 1 m2, amount of spikelets in spike, real and theoretical yield, spike length and density. The next step was the processing of the results where the average value of all the varieties in the amount of ears per 1 m2 was 783 units/m2. The second element of the yield varieties reached the average number of grains per spike 36.2 pieces. And the mean weight of´thousand grains was 44.42 grams.

The comparison of seed production and biomass yield on propagate stands of selected grass varieties
MIMRA, Michal
The topic of the thesis: Comparison of the seed and biomass yields of breeding vegetation cover This thesis was focused on yield ability of the selected ryegrass species grown in the Czech Republic. Experimental fields were based on the land of private working farmer Mr. Pavel Mimra in Slatina u Vysokého Mýta. There were grown three species of ryegrass on the farm in vegetational period of 2013/2014. Monitoring was primarily focused on the formation of yield aspects - the number of the ears, the number of the grains in the ear and the weight of thousand grains. In the vegetational period was also monitored presence of weeds, pests and diseasases and was evaluated total amount of plants and their offsets. The total amount and subsequent use of remaining biomass from breeding covers was also monitored. In the end, there were discovered results compared with theoretical yield. Costs, profits and economical relevance were evaluated in the final part of thesis
