SCS443 ISADORA: late ripening apple cultivar with very high fruit storage ability

Abstract The objective of this study is to describe the agronomic attributes SCS443 Isadora apple tree cultivar and highlight its potential use in Brazil. Obtained by hybridization made at Epagri 2001 between ‘Imperatriz’ ‘Cripps Pink’, after 20 years evaluations carried out Caçador-SC Fraiburgo-SC, ‘SCS443 Isadora’ was originated. This has a wide plasticity adaptation southern Brazilian climate due medium chilling requirement overcome dormancy. It greater resistance main diseases than cv. Gala fruit harvest later Fuji. Its apples have red skin firm flesh (=18 lb), with high sugar content (= 14.5 %) very crunchy juicy texture, as well storage ability post-harvesting. can be stored for 8 months, even refrigerated air atmosphere chambers (21% O2) inhibition ethylene response 1-methylcyclopropene (1-MCP). Even long periods time, indices quality loss, physiological disorders rotting are lower on Fuji apples.
