Breeding of stone rootstock is very important problem for orcharding. In many countries of the world have been obtained a lot of new breeding material for sweet and sour cherries and plums. An analysis was conducted in Cacak (Western Serbia) in the 2006–2007 period to examine major morphological traits of the aerial part and root of suckers derived from mother bushes of three newly vegetative rootstocks for stone fruit species, particularly plum, peach and apricot trees. The newly breed rootstocks have been developed from autochthonous genetic material, their specific designations being: FA 2/53 (Prunus domestica L.), FA 5/7 (P. domestica L.) and FA 6/209 (P. cerasifera Ehrh.). The analysis of suckers of the new rootstocks included the investigation of morphological traits through the determination of: a) length of the aerial part, b) number of feathers on aerial part, c) number of roots, d) length of roots, and e) volume, weight and category of the roots. They developed branch roots and exhibited good length of the aerial part, a substantial number of roots and root dry weight. The FA 2/53 rootstock can be classified into low-vigour rootstocks, FA 5/7 into low to moderately vigorous ones (slightly more vigorous than the FA 2/53 rootstock) and FA 6/209 into moderately vigorous rootstock for stone fruits.
