| h2A | h2A | h2AD | ||
| Petiole length | Petiole length (cm) | 0.630 | 0.715 | 0.733 |
| Leaf area | Ellipse approximation calculated as leaf length (cm) × leaf width (cm) × 3.14 | 0.589 | 0.769 | 0.78 |
| Brix | Degree of brix, measured using a refractometer | 0.357 | 0.724 | 0.765 |
| Fruit hardness | Samples compressed with a 2φ rigid plunger and a compression speed of 10 mm/min | 0.400 | 0.618 | 0.691 |
| Pericarp color | Calculated as L* × b*/a*, where lightness (L*) and hue (a*, b*) were measured by a colorimeter | 0.260 | 0.739 | 0.783 |
a105-ILs: 105 inbred lines; 275-F1s: 275 test F1 hybrids; h2A: heritability based on additive effect model; h2AD: heritability based on additive plus dominant effect model.
