Abstract
Good quality planting material is a perquisite of a successful fruit production. Main sour cherry (Prunus cerasus L.) cultivar in Dalmatia is Maraska. With the aim of improving the quality of planting material, before harvest in the year 2014 in the largest plantation of Maraska in Croatia, selection of trees with elite phenotypic characteristics (n=50) were selected. Samples of leaves and branches from the selected trees were tested on the presence of all viruses compulsory by the EPPO certification sheme as well as Plum pox potyvirus were tested. Out of 50 selected elite trees, 11 of them were found to be free from all of the tested viruses, and just before harvest in the year 2015 they were evaluated visually and characteristics of fruits (length, height and diameter of fruit, length of the petiole, total soluble solids content, total acidity content, pH value of the juice) were measured. High level of intracultivar variability was detected that can be used in an individual clonal selection program.
