The study presents malting quality and agronomic characteristics obtained during testing of barley varieties in the Czech Republic. After the  harvest of 2020, the following spring barley malting varieties were registered: Amidala, Focus, Greenway, KWS Jessie, LG Belcanto, and LG Stamgast. LG Stamgast was recommended for production of the beer with the protected geographical indication České pivo. In addition, the non-malting spring barley variety RGT Gagarin was registered. Amidala, Focus, Greenway, KWS Jessie, LG Belcanto provided malt with the extract content over 83%. These varieties also easily degraded nitrogenous substances. The value of the Kolbach index ranged from 48.6 to 52.1%. Diastatic power was at the optimal level. Degradation of cell walls was also optimal. Friability moved from 89 to 97% and β-glucan content in wort achieved satisfactory values of 65 – 170 mg/l in the given varieties . Wort quality, which is characterized by final attenuation, was at the above average to optimal level of 80.9 – 83.2% in these varieties of spring barley. LG Stamgast showed lower values of proteolytic and cytolytic modification and lower values of final attenuation, which is required for the varieties recommended for the production of the beer with the protected geographical indication České pivo.

The study presents results of malting quality and agronomic characters determined within varieties of Avus, Fandaga, and LG Tosca after a three-year period of testing and Adam and LG Ester after four years of testing with the purpose of obtaining the registration of these spring barley varieties in the Czech Republic. Adam and LG Ester were recommended for the production of beer with the Protected Geographical Indication “České pivo”. Extract from the varieties was at the levels of 82.6 and 81.9%. They exhibited the required lower level of proteolytic modification and apparent final attenuation. Cytolytic modification was also low. Avus, Fandaga, and LG Tosca had a high extract in malt dry matter, which ranged from 83.4 to 84.1%. The varieties had optimal to strong proteolytic modification (the Kolbach index of 46.8–55.6%). Fandaga exhibited the highest content of free amino nitrogen (246 mg/l). Amylolytic and cytolytic modifications were at the optimal level. Wort quality was optimal (apparent final attenuation was between 82.1 and 83.2%). LG Tosca always provided clear wort while other varieties provided weakling opalizing wort.

This study presents the results of malting quality and agronomic characters obtained within state varietal testsof malting barley in the Slovak Republic. After the harvest of 2019, new spring malting barley varieties of Avus,Bernet, and LG Nabuco were registered. The spring barley varieties provided malt with extract content above 83%. All varieties degraded nitrogenous substances easily. The values of Kolbach index ranged from 47.5 to 49.5%. Diastatic power was at the optimal level and moved above the level of 300 WK un. in all the studied varieties. Also, cell wall degradation was optimal and friability was higher than 90%. Content of β-glucans in wort reached favourable values (72–141 mg/l). Quality of wort characterized by apparent final attenuation was at the above average value to the optimal level (81–81.8%) in the studied spring barley varieties.

After harvest 2018 new spring barley malting varieties Cosmopolitan, Ismena, Klarinette, Laureate, LG Aurus, and Runner were registered in the Czech Republic. The spring barley varieties were rich in extract. The varieties Cosmopolitan, Laureate, and LG Aurus had more than 83 % of extract. The values of Kolbach index, diastatic power and apparent final attenuation were at the above average to optimal level in the studied varieties of spring barley. The level of cytolytic modification was at above average to optimal level with the exception of the variety Runner which exhibited higher β-glucan content in wort (192 mg/l). In addition, non-malting varieties of winter six-row varieties Azrah, Impala, Journey, SU Jule, and hybrid variety SU Hylona were registered.

Virulence frequencies to powdery mildew resistances in winter barley cultivars mostly registered in the Czech Republic were studied in 2007 and 2008. Random samples of the air populations originating from winter and spring barley fields were obtained by means of a mobile version of a jet spore sampler. Conidia were sampled by driving across the Czech Republic. In total 349 isolates were studied and 17 differentials were used. The virulence frequencies to specific resistances of given cultivars showed wide range from 0% to 100%. Nine differentials were used to distinguish 134 pathotypes, of which 32 representing 63.9% of isolates were detected in both years. Pathotype 773, which broke down the resistance of eight differentials, was the most abundant. In 2008, lower virulence frequencies to all differentials, and thus lower population complexity, were determined, which may be caused by different regional origins of the isolates examined. Importance of the study of the given pathogen population is discussed in terms of successful breeding of resistant barley cultivars.

The study presents results of malting quality and agronomic characteristics of the LG Verdi, LG Tosca, and Spitfire spring barley varieties that were obtained during a three-year period of testing within the state varietal trials in the Slovak Republic. Extract from the varieties was at the level from 82.9 to 84.1%. The varieties exhibited optimal and high levels of proteolytic modification (47.4 to 52.0%) and satisfactory to optimal levels of final attenuation (80.8 to 81.8%). Degradation of cell walls was high – between 86 and 96%. Beta-glucan content was at a satisfactory to optimal level of 67 to 158 mg/l. In addition, the study presents results which the Suez winter barley variety achieved in a two-year period of state varietal trials. The variety exhibited satisfactory quality of the extract level, optimal level of proteolytic modification and optimal wort composition. This variety had a slow degradation of cell walls, but its beta-glucan content was at the satisfactory level.

The Relationship

This article focuses on the experience of Czech customers with the purchase of products labelled by the Association of Regional Brands and Bohemian Paradise Association. The aim of this paper is to evaluate selected indicators associated with purchasing certified regional products. The studied characteristics focus on the knowledge and perception of several chosen microregional brands and on the purchase of a certified product itself. The article presents the results of research conducted through a questionnaire survey, whose 1390 respondents are residents as well as visitors of eight different micro‑regions in the Czech Republic. Awareness of regional brands within the sample surveyed is around 46 %. The relationship between awareness of regional brand and respondents’ age, education and status towards the region has been identified. The perception of consumers considered, a brand is most often associated with tangible products, namely food and agricultural produce. Consumers view brands chiefly as a guarantee of production in the given region and a certain tradition. Most often, the respondents take notice of brands on the packaging of a particular certified product.

Abstract The article’s aim is to compare the opposite processes of social exclusion and inclusion in South Africa and in the Czech Republic, in the past and at the present time. Even though these societies differ culturally and geographically, the comparison of some important factors, which are causing the exclusion of some people groups, might be interesting. In both cases we will closely follow the social, ethnic and racial groups, which are mostly excluded in the given environment. In South Africa it concerns Black and Coloured Africans, and in the Czech Republic the Roma ethnic minority group, the only ethnic group which is to a high extent excluded. In the history of these two countries we can find a similar historic aspect, both of them had experienced totalitarian regimes. Today, with the benefit of more twenty years, we can see the changes, which both these countries have undergone, and observe as well how these changes influenced the processes of inclusion and exclusion of the given social, racial and ethnic groups.
