3. Coping with Increasing Climate
Uncertainty: Flooding
Disease
and
Fruit
Loss
Excess soil moisture damages tomato plants leading to dramatic loss of yield

4. • Grafting: improved rootstocks
to manage bacterial wilt and
flooding in Solanaceous crops

tomato

5. Rubber tubing: Better for grafting than traditional
clips as it falls off naturally as the plant grows
Grafted plants prove successful in Qatar!

8. Several successful women’s
grafting cooperatives
trained by AVRDC in
Jessore, Bangladesh
Technology well suited to the
landless poor
Grafted seedlings sell for about 5 times
the price of normal seedlings and have
shown themselves to be effective
against bacterial wilt in Jessore
Graft recovery chamber with high humidity

9. Economic impact of AVRDC tomato grafting
technique in Lam Dong province, Vietnam
Parameter Lam Dong province
Yield (t/ha) 73
Adoption rate by tomato farmers 100%
Total area under tomato production (ha, 2011) 6,388.0
Contribution of grafting ($million/yr) 9.3

10. What’s next: Can tomatoes and eggplants grow on trees?
Solanum torvum (Prickly nightshade) as a new grafting
rootstock for eggplants and other Solanaceous spp.
• Highly resistant to common fungal and
bacterial wilts and root knot nematodes.
• Vigorous growth supports higher yield.
• Drought tolerant.
• Locally available root stocks (India,
Thailand)
• Easy to produce as root-stocks.
• Perennial and supports longer duration.
• Berries already used as local vegetable
in Thai Green Curry and Tamil Nadu
cuisine.
