Biological properties of new apple cultivars in the region of Central Serbia

Abstract

Seven relatively new apple cultivars of late maturing time were studied during the three-year period (2004-2006) in the region of Central Serbia. They were as follows: 'Morren's Jonagored', 'Pilot', 'Pinova', 'Delbard Jubilé', 'Braeburn', 'Fuji Naga-fu 2' and 'Fuji Naga-fu 6'. The cultivar 'Idared', as the most grown apple cultivar in Serbia, was used as a standard. The average time of maturation of studied cultivars was from September 18 ('Jonagored') to October 17 (clones of 'Fuji'). The highest average yield of 15.8 kg per tree was achieved by cultivar 'Pinova' and it was significantly higher than other cultivars, including standard. The fruit weight ranged from 174 g ('Pinova') to 229 g ('Jonagored'). Three cultivars ('Pinova', 'Braeburn' and 'Pilot') had significantly lower fruit weight than the standard ('Idared'). New cultivars had higher contents of soluble solids and sugars than 'Idared'. The highest organoleptic scores had cultivars 'Jonagored', 'Pinova' and 'Delbardd Jubilé'. Generally, the best properties were shown by cultivars 'Pinova', 'Jonagored' and 'Fuji Naga-fu 2', so they can be recommended for commercial growing in the region of Central Serbia.

U periodu od tri godine (2004-2006) na području centralne Šumadije proučavano je sedam novijih zimskih sorti jabuke: Jonagored, Pilot, Pinova, Delbard Jubilé, Braeburn, Fuji Naga-fu 2 i Fuji Naga-fu 6, uporedo sa sortom Idared, koja je uzeta kao standard. Proučavane su sledeće osobine: vreme zrenja, rodnost, kao i važnije fizičke, hemijske i organoleptičke osobine ploda. Najbolje osobine pokazala je sorta Pinova, a pored nje za gajenje se mogu preporučiti i sorte Jonagored i Fuji Naga-fu 2.
