Biological properties of summer apple cultivars

Abstract

The paper presents the results of five-year studies of eleven summer apple cultivars in agro ecological conditions of Belgrade fruit growing area. Investigations included the flowering and ripening time, fruitfulness, as well as important physical, chemical and organoleptic fruit properties. The best results were shown in cvs. Vista Bella and Akane, that can be recommended for commercial growing. Following cultivars: Yellow Transparent Rubin and Erich Neumann,s Roter James Grieve can be recommended for growing in small orchards and for local markets fruit sale.

U radu su prikazani petogodišnji rezultati proučavanja jedanaest letnjih sorti jabuke u agroekološkim uslovima beogradskog voćarskog područja. Istraživanjima su obuhvaćeni: vreme cvetanja i zrenja, rodnost, kao i važnije fizičke, hemijske i organoleptičke osobine plodova. Najbolje rezultate pokazale su sorte Vista bela i Akane, koje se mogu preporučiti za gajenje u proizvodnim zasadima. Za gajenje u manjem obimu, za potrebe lokalnog trzišta mogu doći u obzir i sorte Belinik, Rubin i Crveni džejms griv nojman.
