The paper presents two-year results of the study (2008-2009) of the initial and final fruit set in sweet cherry cultivars Kordia, Summit, Karina and Regina grown under agroecological conditions of Čačak (Serbia), which were subjected to different types of pollination. Each of the above mentioned cultivars was investigated under cross-pollination and self-pollination conditions (16 combinations); for each combination 300 flowers were emasculated and pollinated. The study of the initial and final fruit set under the conditions of open pollination was concurrently performed. The characteristics of flowering phenophase as well as in vitro pollen germination of the stated cultivars were monitored. Generally, in all the cultivars fruit set was higher in the first year of study. Karina and Regina had high fruit set rate in both years, in cross- and open pollination. Regina proved to be the best pollinator, especially for Karina, and demonstrated the best in vitro pollen germination in comparison with the other studied cultivars.
