From different autochthonous populations that are present on the territory of Serbia, 17 cherry plum types were selected, characterized by distinctive morphological properties and fruit quality. During the two-year period of research, the following parameters were examined: fruit weight, stone weight, soluble solids content, total sugars content, and total acids content. For all of the examined properties, coefficients of genetic and phenotypic variation, as well as the coefficient of heritability on a broader sense were calculated, based on a two-factorial analysis of variance results. It was determined that genetic variability had a major influence on the total acids content, while at he same time the interaction genotype x year played the decisive role in determining the variability of soluble solids content and total sugars content. Coefficients of genetic and phenotypic variation show that in the cherry plum trees that were examined, the least variation was in the soluble solids contents, and that the highest variation was in the fruit weight. The lowest level of heritability in a broader sense was established in the total sugars content and the highest in the stone weight.
