Cherry (Prunus avium L.) is a long-lived cultivated crop. It is grown in the continental and mediterranean part of the Republic of Croatia. Cherry production requires the cultivation of bigger grain varieties and better coloration of fruits. In addition, early births and achieving full productivity are required from the variety. The survey was conducted in the experimental orchard of the Institute of Fruit Growing of the Croatian Center for Agriculture, Food and Rural Development in Donja Zelina during the year 2020. The study included cultivars ´Kordia´ and ´Regina´ which were grafted on Gisela 5, Gisela 6, Piku 4,2 and PHL-C rootstocks. The aim of this study was to determine the influence of variety and rootstock on the occurrence of individual phenophases in cherries using the BBCH scale. Under the influence of the substrate, the largest differences between PHL-C and PiKu 4,2, in relation to swelling phenophases and generative bud openings of Gisela 5 and Gisela 6, were determined on March 16, 2020. The substrates of Gisela 5 and Gisela 6 influenced the earlier opening of these buds. The occurrence of individual phenophases between the cultivars 'Kordia' and 'Regina', if compared on the same substrates, were almost identical. Only small differences were observed on March 19. and March 24. 2020 when ‘the phenological phases of Regina’ were a little behind the ‘Kordia’ variety. The values on the BBCH scale increased at the fastest rate in the generative phase in March when the cherries reaches a value above 50 (fifty) from the resting phenophase and the mark 00 (zero) in less than a month.
