In the conditions of the Republic of Belarus there were analyzed the results of comparative characteristics of indexes of vegetative growth, yield and fruit quality of apple (Malus) cultivar-rootstock combinations. On the basis on morphological analysis of crown there was determined the general number and density of growing points on tree branch of cv. Antey and Alesya depending on rootstock growth strength. According to the vegetative growth characteristics the trees on rootstock PB-4 showed worse indexes than the trees on dwarf rootstock 62-396. Despite the increasing of planting density on 50% the leaf area of the trees on PB-4 rootstock in-equivalent to hectare was on 2.15-2.5 times lower in comparison with the trees on 62-396 rootstock. According to the density and total number of growing points of encrusting type the trees 62-396 substantially exceeded the ones on PB-4 due to higher growth strength on this rootstock. Using of dwarf rootstock PB-4 led to decrease of average fruit mass on the large-fruited cv. Antey in comparison with 62-396 rootstock. For cv. Alesya with average fruit mass 140-166 gram the type of rootstock did not render substantial influence. Yield per tree and yield per growing area unit for both cultivars was higher at the dwarf rootstock 62-396 in comparison with PB-4 rootstock.
