The aim of the study was to learn about the consumers’ opinions about the technologies used in the production of cereals and their relationship with the acceptance of the bread with added fibre. Computer Assisted Computer Interviewing (CAPI) was carried out in October and November of 2013 within a group of 1000 people aged over 18 years. The participants accepted the use of traditional cross-breeding of cereals varieties in order to obtain seeds of greater nutritional value than the breeding using genetic modifications. Supporters of both technologies were recruited primarily from medium-sized cities and those with vocational education. Opponents of both technologies are mainly people from the cities of over 100 000 residents and people with lower levels of education. The participants accepting the traditional cross-breeding and rejecting genetic modifications lived in larger cities and represented a relatively higher education. A more positive attitude towards the breeding using genetic modifications favoured declaring the willingness to eat bread with added fibre.
