<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Long-term field trials with the apple cultivar ‘Krista’ on different vegetative rootstocks were held at the Polli Horticultural Research Centre (58°07`N, 25°32`E) in Southern Estonia in 2005-2015.

The apple cultivar ‘Krista’ is well suited for growing in the climatic and soil conditions of Estonia. The cultivar performs best on vegetative rootstocks that are well-adapted to the Estonian climate: MM106, E75, B396, M26, M27, and P59. The rootstocks Supporter 1, Supporter 2, Supporter 3, and Supporter 4 did not turn out to be suited for growing in Estonia. The trees grafted on rootstocks MM106, E75, MTT1, and M26 grew taller, had a bigger crown spread and crown volume. In dense orchards with the planting scheme 4 × 1.5 m, trees with a smaller crown diameter may be grown on rootstocks MM27, P59, and Supporter 4.
