Summary
Productivity, fruit quality and biochemical characteristic of 10 new apple (Malus
domestica Borkh.) cultivars were studied at the Lithuanian Institute of Horticulture
in 1999–2005. Trees were grafted on M.26 rootstock at a spacing of 4 x 2.5 m.
Investigations showed that apple trees of cvs. ‘Antej’ and ‘Kovalenkovskoje’
produced the highest cumulative apple yield. The longest period of storage was that
of cv. ‘Sveþestj’, the shortest one – of cv. ‘Jubiliar’ fruits. The largest fruits have
cvs. ‘Verbnoje’ and ‘Jubiliar’, the smallest – cv. ‘Sveþestj’. Fruits of cv. ‘Delikates’
and ‘Sveþestj’ had better quality and chemical characteristic in comparison with
other apple cultivars. ‘Verbnoje’, ‘Bolotovskoje’ and ‘Sveþestj’ were distinguished
for firmness of skin, ‘Bolotovskoje’ and ‘Sveþestj’ – for firmness of flesh.
Key words: apple, chemical characteristic, cultivars, fruit quality, productivity.
