In this paper, during the three-year period of testing, the variability of the flowering time and fruit set in 13 Oblačinska sour cherry clones was studied. It was found that on average for all three years of testing, the start of flowering was in the period from 06.04. until 12.04., full flowering from 09.04. until 15.04, and the end of flowering from 18.04. until 23.04. The number of fruit set ranged from 41.09% to 71.61%, and the number of fruit harvested from 16.31% to 47.74%. The greatest share of genetic variability in total phenotypic variability was determined for the start of flowering (64.92%). The coefficients of genetic and phenotypic variation were the highest for the number of fruit harvested (17.99%; 19.36%). The high values of the heritability coefficients for the studied properties (over 80%) are obtained, that evidence of the low effect of the environment factors on the expression of these properties and their possible improvement through selection.
