Abstract The mango cultivar INDO‑18 (accession no. 50847370) has been recently released by the Indonesian Fruit Germplasm Centre for commercial cultivation in the tropical highlands of West Java. This study provides a comprehensive characterisation of the cultivar’s physicochemical properties, nutritional composition, and consumer‑perceived sensory quality. Fruit samples (n = 120) harvested at optimal ripeness (Stage 3, 75 % peel colour change) were analysed for total soluble solids (TSS), titratable acidity (TA), pH, firmness, colour parameters (L*, a*, b*), vitamin C, total carotenoids, total phenolics, and antioxidant capacity (DPPH assay). A trained sensory panel (n = 30) evaluated appearance, aroma, taste, texture and overall acceptability using a 9‑point hedonic scale. Results show that INDO‑18 exhibits TSS = 15.8 ± 0.7 % Brix , TA = 0.45 ± 0.03 % citric acid , pH = 3.8 ± 0.1 , and a firmness of 4.2 ± 0.4 N . Nutritionally, the fruit provides 45 mg 100 g⁻¹ vitamin C , 3.2 mg 100 g⁻¹ β‑carotene , and 210 mg 100 g⁻¹ total phenolics , conferring an antioxidant capacity of 12.5 µmol TE g⁻¹ . Sensory scores were significantly higher (p < 0.05) for aroma (7.8 ± 0.6) and overall acceptability (8.1 ± 0.4) compared with the reference cultivar ‘Carabao’. The combination of high sugar‑acid balance, robust aromatic profile, and superior textural attributes positions INDO‑18 as a promising candidate for fresh‑market distribution and value‑added processing.

Interpretation: INDO‑18 displayed a significantly higher sugar content (TSS) while maintaining comparable acidity, resulting in an improved (S/A ≈ 35) favorable for consumer perception. The deeper red hue (higher a*) aligns with market preferences for visually attractive mangoes. 6.2 Nutritional Composition | Component | INDO‑18 | Carabao | % Difference | |-----------|---------|---------|--------------| | Vitamin C (mg 100 g⁻¹) | 45 ± 2 | 38 ± 3 | +18 % | | β‑Carotene (mg 100 g⁻¹) | 3.2 ± 0.2 | 2.4 ± 0.2 | +33 % | | Total Phenolics (GAE mg 100 g⁻¹) | 210 ± 12 | 180 ± 10 | +17 % | | DPPH Antioxidant (µmol TE g⁻¹) | 12.5 ± 0.6 | 10.3 ± 0.5 | +21 % |

The cultivar, derived from a cross between the elite Indian cultivar ‘Alphonso’ and the local variety ‘Nam Dok Mai’, was selected for its early‑season fruiting, moderate tree vigor, and tolerance to anthracnose (caused by Colletotrichum gloeosporioides ). Preliminary field trials indicated a promising market‑ready fruit size (average weight ≈ 250 g) and an appealing orange‑red peel colour. However, comprehensive data on its post‑harvest quality attributes remain lacking.
