4. II. GENEBANK (CIP – Lima, Peru)
• The world’s largest in vitro genebank which maintains
clonal and seed collections for over 100 years.
• Over 21,000 accessions of potato, sweetpotato, and
Andean root and tuber crops
6. III. IMPORTANCE OF POTATOES
• Third important food crop in the world
(380 million t/ 19 million ha in 2014 -
FAOSTAT)
• High yielding ability (100 t/ha)
• One of the major cash crops in SSA,
including Rwanda

9. One medium size tuber (150 g) may
contain:
• Potassium : 620 mg – more than a
banana
• Vitamin C: 45% of daily requirement for a
man
• Dietary Fiber : 13% of daily requirement
for a man
• Healthy food: Lack of fat, sodium and
cholesterol (major heath problems)
25. VI. YIELD GAP
• Yield Gap (Yg) = Potential Yield (Yp) –
Actual Yield (Ya)
• Yg is extremely high in SSA compared to
developed countries
• Yg can be significantly reduced by
addressing identified gap drivers
26. VII. TAKE-AWAY MESSAGE
Clean seed
Fertilizers
Chemicals (pests and diseases control)
3 entry points for a successful

27. Acknowledgements
We would like to acknowledge Humidtropics and the CGIAR Fund Donors
for their provision of core and project-specific funding without which this
research could not deliver results that eventually positively impact the lives
of millions of smallholder farmers in tropical Americas, Asia and Africa.
