... rs and rootstocks. The main objective of the study was to evaluate the service tree population in Eastern Serbia in order to single out good selections whose fruit can be used fresh or processed in the human diet, as well as genotypes suitable for the development of new cultivars and rootstocks. The service tree population was analyzed for tree age, tree size and major fruit properties (shape, size and soluble solids content). Small-sized, medium to large and large fruits ranging in weight from 7.5-9.8 g, 10.3-18.6 g and 21.7-25.6 g were found in 52.3%, 41.1% and 6.60% trees, respectively, within the test population. Fruit length was 18.6-33.4 mm, fruit thickness 22.8-37.4 mm, stalk length 1.8-3.7 mm, soluble solids content 15.7-22.5%. The study also presents 484 GENETIKA, Vol. 44, No.3, 483-490, 2012 properties of some superior trees which require greater attention in terms of propagation, collection activities and commercial cultivation.
