Abstract
A trial with four cultivars ‘Talvenauding’, ‘Meelis’, ‘Alro’ and ‘Sinap Orlovskij’ grafted on clonal rootstocks M.26, B.9, B.545, B.396 and E.75 was carried out at the Polli Horticultural Research Centre in the spring of 2001. Fruit yield and vegetative growth were assessed annually. Rootstocks B.9, B.396 and M.26 significantly reduced vegetative growth of apple tree (trunk diameter and shoot length during the first four years), whereas trees on rootstock B.545 had the strongest growth. Scion cultivars on B.9, B.396 and B.545 were the earliest to start cropping. Trees grafted onto them started to yield in the second year after planting. The highest cumulative yield was obtained on B.9 and B.396 followed by M.26. The lowest yield and the smallest fruits were from trees on rootstock E.75. The highest productivity up to 4 years after planting was obtained from the trees of ‘Sinap Orlovskij’ on B.396 and M.26.
