3. General information Country: Viet Nam
Principal Investigator: Mr. Nguyen The Nhuan
Organization: Potato, Vegetable and Flower Research Center
Project Duration: Three years from July, 2016 to July, 2019

4. I. Introduction Total production per year Area: 30.000 - 35,000 ha
Productivity: 600,000 tons
Cultivated area can be expanded to 100,000 ha
Current averaged yield
16-18tons per ha

5. Distribution of potato cultivation
Red River Delta (70-80%)
- Cultivation: Open Field
- Cropping season: 1
Dalat, Lam Dong province (20-30%)
- Cultivation: Green house, Open Field
- Cropping season: 2 – 3

6. Red River Delta (9 provinces)
Total cultivated areas: 20,000 ha
Averaged yield: tons/ha
Advantages
Cropping season from Nov. – Jan.
Large production area
Lower costs of labour, land and irrigation
Disadvantages
One season production
Low yield potential
Lower quality (lower dry matter)

7. Red River Delta
Low costs of labour and land
and irrigation

8. Lam Dong Province Disadvantages Advantages
- Favorable climate conditions
- Year round production
- High yield potential and quality
- High potential of Land expansion
- Plastic houses
Disadvantages
- High costs of labor and land rental
- High cost for irrigation during the dry season
- High cost for pests and diseases control during the rainy season

9. Sprinklers irrigation
Harvested by machine

10. Potato production Main varieties # 07, PO3, Atlantic, TK96.1
Sonara, Diamant
Current hybrid potential cultivars: TK10.6, TKC33

11. Problems Late blight Bacterial wilt Viruses Common scab Erwinia rot
Fusarium rot and wilt

12. Can not be harvested because of Late Blight

13. Potato Breeding Targets
Late blight resistance
Virus resistance
Common scab resistance
Processing quality (chipping)
Colour potatoes
Baby potatoes

15. TK96.1
Atlantic

16. Seed potato production in VietNam
In vitro Plants
Micro-tubers
G0 (Green house)
Domestic production is only about 30%
G1, G2 (Field)
Imports from China, South Korea ...
For Farmers

17. ELISA test for virus PVX, PVY affection

18. II. Main Activities for the first year 1) Evaluating Korean cultivars 2) Hybriding promising clones 3) Establising Aeroponic cultivation model 4) Establising ultra-pure seed production protocol

21. III. SUGGESTIONS FOR THE PROJECT - Starting the project soon - Supporting the Korean cultivars for evaluation - Training diseases test techniques - Changing germplast for hybriding

22. IV. Project Impacts and Recommendations
Create promissing cultivars reducing potato seeds import from other countries
Stabilizing and growing the potato market
Supplying healthy mini-tubers to processing companies in Viet Nam.
* Recommendations
Aeroponic cultivation is new for the PVFC Korean experts to the PVFC.

23. V. Future Plan
Next year activities are simialar to those in the first year. At the second year, it is expected to produce healthy mini-tubers to purchase to processing companies and growers at Da Lat.
