Four new aroma hop varieties – Saaz Brilliant, Saaz Comfort, Saaz Shine and Mimosa – were registered in the Czech Republic in 2019. All of the new hop varieties have significantly higher yields than the traditional Saaz aroma variety. Saaz Comfort has the significantly highest content of alpha acids (5.59%) whereas Mimosa has the significantly lowest content of alpha acids (1.90%). The Saaz Comfort and Saaz Brilliant varieties show a variability of alpha acid content below 20%. The other hop varieties, Saaz Shine and Mimosa, as well as Saaz, have a variability of alpha acid content above 25%. Mimosa has the significantly highest content of beta acids (6.07%). Mimosa shows the highest average cohumulone content (29.29% rel.) whereas Saaz Comfort has the lowest cohumulone content (18.04% rel.). Saaz Comfort and Saaz Shine have the highest average contents of hop essential oils (0.84% w. and 0.75% w., respectively). The Saaz, Saaz Shine and Saaz Brilliant varieties show the significantly highest farnesene contents (13.47% rel., 12.50% rel. and 12.38% rel., respectively), which are higher than those of Saaz Comfort and Mimosa.

In the last year, new hybrid hop (Humulus lupulus L.) variety Agnus was released for cultivation in the Czech Republic. It has been necessary to prepare the quality system of Agnus identification from other Czech genotypes and characterise the germplasm of this variety by molecular methods. We proved that utilization of five STS primer combinations successfully and completely identified and determined Czech released varieties and new promising breeding materials. The use of STS method was also very effective and sensitive for control of authenticity and purity of variety Agnus in multipropagation cycle. The study of genetic diversity of 61 hop varieties by RAPD, STS, ISSR and AFLP methods confirmed, that germplasm of variety Agnus has ranked among high-alfa varieties. The results can be successfully used for identification, germplasm management, genetic studies and breeding purposes by breeders, multipropagators and hop growers.

Collecting of Carabidae was conducted using pitfall traps at four sites. The first two sites (T1 + T2) were at the slope of Macošská stráň and the other two sites (T3 + T4) at the slope of Vilémovická stráň. The study was done in 2008 and 2009. At Macošská stráň in 2008, 21 species of Carabidae with the total number of 228 individuals were found and in 2009, 18 species of the total number of 116 specimens were collected. At Vilémovická stráň in 2008, 22 species of Carabidae with the total number of 1977 specimens were found and in 2009, 21 species of the total number of 623 specimens were caught. In terms of classification of relictness, Macošská stráň in 2008 was dominated by species of adaptable group A (60%), species of eurytop group (E) were represented by 35% and of relic group (R) by 5%. In 2009, the same representation of species of groups A and E (47%) were found and the species of group R were represented by 6%. Vilémovická stráň in 2008 was dominated by species of group A (52%), species of group E were represented by 43% and of group R by 5%. In 2009 also dominated species of group A (54%), species of group E were represented by 41% and of group R by 5%. In the studied area we reported four endangered species of Carabidae protected by Law (No. 395/1992 Coll.) as amended, these were Calosoma auropunctatum (critically endangered), Brachinus crepitans, Carabus ullrichii and Cicindela campestris (endangered) and two species listed under the Red List of Threatened Species of the Czech Republic (Veselý et al., 2005). One of the species is listed as vulnerable (Calosoma auropunctatum) and one as near endangered (Carabus cancellatus). Another significant species found on the monitored sites was Aptinus bombarda.

Araneofauna of vineyards is relatively known in Central Europe but we have a lack of knowledge about araneofauna which occur directly on the vine plants. Our investigation was focused on spiders which live on vine plants, especially on the vine plants trunks. We investigated spiders in six vineyards in southern Moravia (Šatov, Mikulov, Popice, Morkůvky, Nosislav and Blučina). Vineyards were under different soil management, traps were placed on different parts of particular locality (terraced and plain) and all localities were under integrated pest management. We employed two types of cardboard traps for spider collecting during whole vegetation season. Altogether, we collected 21 spider species which belong to seven families. The most important species was Marpissa nivoyi (Lucas, 1836), which is mentioned in the Red List as vulnerable (VU) and Sibianor tantulus (Simon, 1868) which had unknown distribution in the Czech Republic. The other very interesting result is that the most common species is myrmecomorph Synageles venator (Lucas, 1836), which is scarcely recorded in such huge numbers as we documented in our study.

The contribution “Anti-state Crimes in Modern Codifications” deals with the topic of anti-state crimes during centuries. Firstly, legal concepts in the pre-state period are mentioned. Then the attention is paid on the evolution of this institute in the Euro-Atlantic area. From this point of view, there are mentioned mainly regulations from England (1351), France (1810), Germany (1871) and Soviet Union (1958) which could be remarked as the most important for the development of other countries. On the other hand, it also reminds the development of codifications in Czechoslovakia, the Czech Republic and Slovakia, which were affected by the Austro-Hungarian legislations as well as German and Soviet approaches. The Czech current arrangement generally does not depart from the other European samples, but it cannot be omitted that in the Czech Republic it is distinguished the penal concept of the high treason (Landesverrat, vlastizrada) from the constitutional concept (Hochverrat, velezrada) which is dedicated to the presidential anti-state activities. The contribution also indicates that the concept of anti-state crimes in countries has not been unified and it has been varying according to various experiences and attitudes.

The upper values of the extractability of trace elements (As, Be, Cd, Co, Cr, Cu, Ni, Pb and Zn) in 2 mol/L HNO<sub>3</sub> and 0.025 mol/L ethylenediaminetetraacetic acid (EDTA) (compared with their pseudototal content in aqua regia) for determination of prevailing anthropogenic and geogenic soil load were proposed and compared with the results of the other 30 Fluvisol samples collected from the Labe fluvial zone. The increased geogenic load of Fluvisols was confirmed in the case of Be and As in some localities where low extractability with increased pseudototal contents were detected as opposed to the other elements when their increased pseudototal contents were followed by their increased extractability. The maps of probability of increased geogenic soil load in the area of the Czech Republic based on the comparison of geological substrates and trace element load were constructed. The combination of proposed elements extractability values for geogenic load together with developed maps is a suitable tool for the definition of prevailing Fluvisol or sediment load on some localities in the whole area of the Czech Republic. The results can be also a useful tool in the decision making processes regarding dredged sediment application on agricultural soil (support tool for legislative norms, Direction No. 257/2009 Sb.).

A survey to estimate the prevalence of verotoxigenic E. coli (VTEC) or enterohaemorrhagic E. coli (EHEC) in rectal swabs from healthy dairy cattle aged three weeks, three months and one year was conducted in three herds from the Czech Republic. Screening for the presence of the stx1, stx2 and eaeA genes in faecal swab cultures was performed by PCR, and in positive samples, isolated colonies were examined. Immunomagnetic separation was used for the isolation of the VTEC serogroup O157 from samples. VTEC were detected in animals from all three herds under study. In the group of 3-week-old calves, VTEC were only detected in samples collected in the summer months. However, in the other age-groups, VTEC were detected in both the summer and winter months. EHEC shedding was observed in 30 to 100% of the total samples collected from cattle aged three months and one year in the summer months, and in 30 to 60% of samples taken in the winter months. EHEC strains of serogroup O157 were detected in two herds. The range of verotoxins shed by VTEC isolates of serogroup O157 differed between herds. Besides serogroup O157, additional EHEC belonging to the antigen groups O26, O103, O128 and O153 have been identified, and in some of them, no somatic antigen was detected.

Abstract In 2015–2016, 6,429 km medium-voltage power lines with 76,430 pylons were checked for bird mortality in the Czech Republic. 1,326 bird victims of power lines were found, 156 of which died after collisions, and 1,170 birds were electrocuted. They belonged to 60 species from 12 orders, and birds of prey made up almost half of all victims. Steel pylons bearing several cross-arms including upper and crosswise jumpers were identified as most dangerous from the electrocution point of view. On the other hand, pylons in straight lines with Pařát cross-arms (triangular arrangement of conductors without any horizontal bar) were among the least dangerous, and when they had a simple perch fitted below the cross-arm, no mortality was recorded. But these pylons are new in practice and despite becoming widely used recently, they form less than one tenth of all pylons in the Czech Republic. On other pylons various types of mitigation measures have been installed. Commonly used plastic covers and plastic strips have proved to be especially effective, but only in cases when they are undamaged and correctly installed.

This paper deals with problems of rural tourism development. The works is focused on researching the situation in the area of rural tourism in the Czech Republic, on understanding the attitudes of entrepreneurial sphere and rural population to this entrepreneurship and mainly on the determination of limiting factors that prevent this form of tourism from a more distinctive development. Rural tourism in the Czech Republic is still in the initiating stage of its development and it is not as developed as in some countries in West Europe. This goal has been reached with the help of primary questionnaire inquiry among business and agricultural subjects in rural areas in the individual regions and the detail results of this questionnaire inquiry are enclosed to the following paper. These identified factors were mainly insufficient financial means and at the same time insufficient state assistance connected with this. Insufficient awareness of this support as well as its inaccessibility for small business appears to be a difficulty, too. From the other obstacles, we can mention the current legislation system, bureaucracy, the state of communication and tourist infrastructure, fears of neighbours’ intolerance and losing privacy and also unfamiliarity and little experience.

Researchers analyzing self-employment in post-communist Eastern Europe have frequently adopted a “dualist” model which relegates the self-employed to marginal sectors of the economy. This paper challenges the dualist approach and argues that the self-employed cannot be regarded as refugees from poverty with few resources and few opportunities to earn high incomes and accumulate wealth. Data from the Czech Republic, Poland, and Slovakia are used to show that self-employment in post-communist Eastern Europe encompasses two distinct class locations: the individually self-employed on the one hand, whose socioeconomic status differs little from that of ordinary workers, and employers on the other, who receive incomes and possess assets far in excess of that of both the individually self-employed and ordinary workers. A proper understanding of the manner in which systems of stratification have changed in Eastern Europe thus requires that one acknowledge processes of differentiation among the self-employed as well as the importance of property ownership in generating new forms of social inequality in the post-communist period.
