Mahaleb cherry (Prunus mahaleb L.) is the most widely used rootstock for sweet
cherries in Latvia, however it has several disadvantages - strong vigour of grafted trees and an
intolerance to heavy, waterlogged soils. The aim of the study was to test the suitability of
rootstocks of different origins for winter-hard sweet cherry cultivar in Latvian climate. The trial
was established in the spring of 2014 at the Institute of Horticulture (LatHort) to test four clonal
rootstocks: ‘PiKu 1’, PHL-A’, ‘GiSelA 5’, ‘VSL-1’, and generative rootstock P. mahaleb
(control) grafted with cultivar ‘Anu’ (Estonian breeding). Cherries were planted at 5×3.5 m in a
random block design in three replications with three trees per plot. Tree height, annual growth of
shoots, the viability of trees after wintering period and the intensity of flowering and production
were evaluated in 2016–2019. Sweet cherry cultivar ‘Anu’ had the best overall winter-hardiness
in the combinations with rootstocks ‘GiSelA 5’ and P. mahaleb. The highest intensity of
flowering and production were observed in trees grafted on ‘GiSelA 5’. Trees on ‘VSL-1’ had
the highest decease rate and the lowest winter hardiness.
