The article presents results of research on preference of the regional food in Vysočina Region in the Czech Republic, with main focus on awareness analysis of Vysočina regional labels. Presented findings are a part of longitudinal research that aims to analyse the evolution of Czech regional labels and their impact on regional development. The questionnaire survey was conducted between January and March 2015 on the sample of 819 respondents from the Vysočina Region. The data have been processed with correspondence analysis and showed that half of respondents prefer regional food, but the results differ in each district, the highest preferences were reported in Jihlava and Třebíč districts. Awareness of the regional labels is rising in comparison with results of the research in 2012. To test respondents’ knowledge they were asked to identify regional labels: two existing - VYSOČINA Regional Product®, Regional Food Vysočina Region and also nonexistent label From Our Region Vysočina. The awareness of regional labels was tested according to chosen sociodemographic factors: gender, age, residence in each district of the region and residence in town or village.

Food labels allow producers to promote the unique selling points of their products and help consumers buy products with value-adding qualities. The aim of the present article is hence to explore Czech food producers’ expectations and experience with selected food labels. The selection was narrowed down to enterprises that had succeeded in the certification processes within the food labeling systems of European quality and origin labels (protected designation of origin (PDO), protected geographical indication (PGI), and traditional specialty guaranteed (TSG)), as well as schemes that fall under the remit of the Ministry of Agriculture of the Czech Republic, such as Klasa (Česká potravina/Czech food, Regionální potravina/regional food, and BIO). The research was made using an online questionnaire in January–February 2018, and was focused on determining possible discrepancies in expectations that the companies had before applying for quality/origin labels and their actual experience with the labelling systems, the benefits they had gained, and their overall experience with the labels. To compare the respondents’ expectations and their actual experience, both the non-parametric Wilcoxon test and t-test were used. The results show that the respondents positively evaluated the effects of marketing communication, but their expectations had been higher than what they experienced.

The article presents results of research study that focused on the recognition of the Vysočina regional labels among the consumers in the region in connection with media analysis about the topic. Research among consumers was conducted in each district of Vysočina Region (Jihlava, Žďár nad Sázavou, Třebíč, Havlíčkův Brod and Pelhřimov) by interviewing a sample of 819 respondents, selected by quota sampling methods. The research was aimed at analysing the ability of respondents to recognise and diff erentiate two existing regional labels VYSOČINA Regional Product®, Regional Food Vysočina Region and also nonexistent brand From Our Region Vysočina, created by authors. Data have been processed with correspondence analysis and showed that respondents connect diff erent characteristics with the labels. Media analysis of the Vysočina regional labels revealed that media may help building awareness about the labels but they do not shape respondents' views on them. Examining the link between the frequency of diff erent types of information in media and their potential impact on the labels' pereception by consumers have shown distorted image. Stronger consensus between research and media analysis have been examined only on importance of products' origin, which can be viewed as a logical inference from the name of the labels.

The article analyses the customer attitude towards the qualities and benefits of organic agriculture production for farmers and customers in the Czech Republic, comparing the situation in 2016 and 2019. More than 2500 respondents were subject to the marketing research in the years 2016 and 2019. The data were processed using correspondence analysis and logistic regression. The research study shows that the number of respondents who consider organic food is growing; at the same time, there is a rather large share of consumers who believe organic food to be of better quality. The results show a favourable change in the popularity of organic food. While, in 2016, the main decisive factor in shopping for organic food was its price, in 2019, the main criterion, for the respondents, was quality, with the criterion of price being complemented by the perception of organic food as healthier than conventional food. At the same time, it was established that, the amount spent on organic food in 2019 was higher than that in 2016. This finding was in positive correlation with the increase in respondents’ income. For farmers, organic farming is a promising alternative to conventional agriculture due to a rising demand for organic produce.
