Abstract

Abstract The most common apple rootstocks in Finland are YP (Yltöinen, Piikkiö) and A2. Their effects on yields and winter hardiness were studied at Häme Research Station in Pälkäne (61°20′N and 24°13′E) near Tampere. The scion varieties grafted on YP yielded better than those grafted on A2 in spite of a lower blooming rate. Both rootstocks had similar vigour and winter hardiness. Their winter hardiness proved acceptable, but both A2 and YP are vigorous and there is a demand for new dwarfing apple rootstock for Finnish climatic conditions.
