Two-year-old apple trees on rootstock M.26 were planted in an orchard in 2001. Trees were placed at 4 × 2 m and 3 trees presented selection, 1 tree per replication. Apple tree yield, fruit size, picking time, storage life, fruit quality, chemical content and colour coordinates were investigated. It was determined that cumulative yield of selections No 20244 and No 21199 was the highest. The longest period of storage had selection No 21199, standard cultivars ‘Tellissaare’ and ‘Štaris’. Fruit taste and quality of selections No 20244, No 22159 and cultivar ‘Auksis’ were the best. Selections No 20244, No 21664, No 22159 and cultivar ‘Auksis’ had uniform fruit size. Cultivars ‘Štaris’, ‘Auksis’, selections No 20244 and No 22159 had the largest fruits. Biochemical characteristics of fruit distinguished selections No 21199 and No 21664. Fruit skin firmness of selections No 22159 and cultivar ‘Tellissaare’ was the highest, flesh firmness – of selection No 19943 and cultivar ‘Tellissaare’.
