| Scientific Name | Citrus unshiu Marc. (Satsuma mandarin); cultivar ‘Okitsu Wase’ |
| Type | Early‑season satsuma mandarin; seedless / parthenocarpic; easy‑peel |
| Origin | Japan; developed from a seed produced by controlled pollination of ‘Miyagawa’ satsuma (1940) |
| Primary Use / Market | Fresh fruit; domestic market; export potential (requires careful post‑harvest handling) |
| Plant Type | Evergreen citrus tree |
| Tree Habit | Medium‑sized, spreading tree with an open habit (suited to higher‑density planting systems) |
| Flowering / Fruit Set | Can set fruit without pollination (parthenocarpic), contributing to low/absent seeds |
| Bearing Age | Typically starts bearing about 1–2 years after planting when grafted (varies by nursery stock and management) |
| Ripening / Harvest Window | Early season. Example: in southern Australia, main harvest is typically concentrated in April, with quality declining quickly after early May if fruit is left on‑tree |
| Fruit Traits | Flattened fruit; smooth fine skin; internal maturity can occur before full external color (fruit may be edible while still partly green) |
| Quality Notes | Very high juice content has been reported in early harvest periods; fruit can become soft/puffy if held too long on the tree |
| Stress / Climate Notes | Satsumas are among the more cold‑tolerant citrus types; however, fruit can be sensitive to heat/sunburn when exposed |
