Resources & Knowledge Products
The Potato Council of Tanzania curates the technical knowledge, policy frameworks, and market intelligence that the sector needs to professionalise. This page is the single point of access to our library — for farmers, seed multipliers, processors, researchers, investors, and partners.
Tanzania Potato Variety Catalog
Developed in collaboration with the Tanzania Official Seed Certification Institute (TOSCI) and the Embassy of the Kingdom of the Netherlands, the Variety Catalog is the authoritative register of all potato varieties officially approved for commercial cultivation in Tanzania.
It is essential reading for anyone deciding what to plant, where to plant it, and what to plant it for.
Featured Varieties
| Variety | End-Use | Maturity | Yield Potential | Notable Traits |
|---|---|---|---|---|
| Markies | French fries / crisps | Late (>4 months) | High (>40 t/ha) | Number-one variety for the processing industry; yellow skin |
| Asante | Fresh market | Medium (3–4 months) | High (>40 t/ha) | Resistant to late blight; known as Victoria in Uganda |
| Arizona | Retail market | Early (<3 months) | High (>40 t/ha) | Large oval tubers; high tolerance to bruising |
| Manitou | Retail / chips | Late (>4 months) | Very high (60–70 t/ha) | Beautiful red skin; proven yield under irrigation |
| Sherekea | Fresh market | Late (>4 months) | High (>40 t/ha) | Round tubers with red skin; cream flesh |
| Tengeru | Multipurpose | Late (>4 months) | Med-high (35–45 t/ha) | Resistant to late blight; white-cream skin |
| Unica | Fresh / processing | Medium | High | TARI-released; climate-resilient |
| Shangi | Fresh market | Medium | Medium-high | Widely adopted in East Africa |
| Sagitta | Processing | Medium-late | Very high | Premium processing variety |
| Rumba | Multipurpose | Medium | Medium-high | Resistant to PCN |
| Sifra | Multipurpose | Medium | Medium-high | Resistant to PCN |
The full Catalog also covers Kuroda, Destiny, Costanera, Saviola, Roko, and additional cultivars in trial. Tanzania currently has 16 registered potato varieties — the most diverse formal catalog in East Africa.
The Catalog is regularly updated as new cultivars complete the national performance trials process.

National Round Potato Development Strategy (In Validation)
Tanzania’s first comprehensive policy framework for the potato sector is currently undergoing final technical review and stakeholder validation. Once adopted, it will serve as the authoritative roadmap guiding government investment, regulatory reform, and private-sector engagement across the entire value chain for the next decade.
Strategic Pillars
- Seed System Strengthening — certified seed scale-up, multiplication zones, foundation seed governance.
- Post-Harvest Infrastructure — cold storage, grading and packaging centres, aggregation hubs.
- Market Access — domestic, regional, and export market development.
- Agro-Processing Incentives — tax instruments, finance, and infrastructure for crisps, frozen fries, and starch.
- Research-Extension Alignment — closing the gap between TARI laboratories and farmers’ fields.
- Trade Reform — eliminating the lumbesa system, standardising weights and measures, modernising market governance.

EAC Seed Potato Trade Strategy
The East African Community Seed Potato Trade Strategy is the regional framework that establishes harmonised standards for cross-border seed potato trade across the seven EAC member states. It addresses:
- Phytosanitary protocols — pest and disease management standards.
- Certification equivalency — mutual recognition of seed quality grades.
- Quarantine procedures — at-the-border verification.
- Dispute resolution mechanisms — for trade conflicts.
For Tanzanian seed multipliers and export-oriented producers, this Strategy creates the predictable regulatory environment needed to scale regional trade. The Jumuiya Potato Platform is the body operationalising it.
