Phenophase of flowering and pollen germination of seven peach cultivars, i.e. Goldcrest, Springold, Julija, Dixired, Redhaven, Dora and Southland were being studied over 2004-2005. The investigated flowering properties are as follows: flowering - onset, full bloom, end, and the amount. Pollen germination was investigated by in vitro pollen germination test which includes seeding pollen of each cultivar into two Petri dishes at previously established medium concentration, i.e. 12% sucrose and 1% agar. The results of the study have shown that differences among cultivars were observed only over the period flowering onset, suggesting that early flowering - early ripening regularity cannot be established. The amount of flowering ranged from 3 (cvs Dixired and Southland) to 5 (cv Springold) in the first year of study, whereas it was somewhat lower in all cultivars over the second year of study ranging from 1 (cvs Dixired and Dora) to 3 (cv Julija). All studied cultivars had high, rather uniform pollen germination rate.
