In the conditions of the Republic of Belarus there were presented results of a study of basic economic and biological indexes of columnar apple (Malus) tree varieties 'Valyuta' and 'President' of the All-Russian Breeding and Technological Institute for Horticulture and Nursery on the rootstocks 62-396, 54-118, M26 and 106-13. Research results showed that the studied varieties 'Valyuta' and 'President' grown on 62-396, 54-118 rootctocks were characterized by high fruit growth intensity. The highest trees at all varieties appeared to be on the rootstocks 106-13 and 54-118. Columnar apple varieties 'President' and 'Valyuta' on the rootstocks 62-396, M26 and 54-118 started fruiting on the second year. The highest total yield for 2 years of investigation was produced by the following inoculated and rootstocked combinations: 'Valyuta' variety on the rootstocks M26 and 62-396 (49, 47.2, tons per hectare), 'President' variety on the rootstocks M26, 54-118 (37.9 and 31.2 tons per hectare accordingly). The lowest total yield was at the variety 'President' on the rootstock 106-13 (5.4 tons per hectare).
