This study aimed to identify maturity indexes for the ideal harvest point of ‘SCS426 Venice’ apples intended for immediate marketing or cold storage. The fruits were harvested weekly, in Fraiburgo, SC, between 144-172 days after full bloom (DAFB) and were evaluated one day after harvest and after storage for 240 days under air atmosphere (AA) at 0.5 °C and 265 days under controlled atmosphere (CA), at 0.7 °C. Maturity indexes for ‘SCS426 Venice’ apples intended for immediate marketing range from 15.3 to 16.5 lb for pulp firmness, 12.9 to 13.4% for soluble solids content (SSC), 0.291 to 0.338% for titratable acidity (TA), 8.2 to 9 for starch index (scale ranging from 1 to 9) and 3.7 to 4.3 for the skin background color (scale 1to 5). Maturity indexes for ‘SCS426 Venice’ apples intended for storage (AA and CA) range from 17.2 to 18.0 lb for pulp firmness, 11.8 to 12.5% for SSC, 0.350 to 0.356% for TA, 3.0 to 5.5 for starch index and 2.1 to 3.1 for the skin background color.
