Sess05 2 vanderzaag – asian seed potato production systems related to the highlands of africa

  1. 1. Asian Seed Potato Production Systems Related to the Highlands of Africa
  2. 2. Four Potato Cropping Zones of China Multi‐crop Zone IV is like the Highlands of Africa
  3. 3. Asian Seed Potato Production Systems Related to the Highlands of Africa Locations: Yunnan, China Dalat, Vietnam  Mountain Trail, the Philippines Elevation: 1500 to 3,000 m asl Latitude: 11 to 24 N Constraints: late blight,  bacterial wilt (lower elevations),  viruses
  4. 4. National Program Collaboration with CIP Over the past 30 years 1. Varietal development with LB, BW & Virus  resistance 2. Tissue Culture demystified 3. Simple, informal, on‐farm Seed Programs  developed
  5. 5. Farmers doing Tissue Culture and RMT in their homes  1982 in Vietnam
  6. 6. Professor Wang Jun with tissue culture plants for RMT 1986 in Yunnan, China
  7. 7. Varietal Development 1. Mexican Clones: CFK69.1, B71.240.2, I1085,  Utatlan 2. Local Breeding: Mexican clones X CIP LB  germplasm 3. Products:  Cooperation 88, Igorota …
  8. 8. C88: late blight & virus resistance, excellent fresh & processed 2009 in Southwest China
  9. 9. Cooperation 88 (C88): yield 35 – 80 T/ha 2010 in Southwest China
  10. 10. Igorota:  late blight & virus resistance, excellent fresh & processed  2011 in Mountain Trail, the Philippines
  11. 11. Tissue Culture in Farmer’s home 2010 in Dalat, Vietnam
  12. 12. RMT program by farmer: 1.5M rooted cuttings sold/year 2012 in Dalat, Vietnam
  13. 13. Rooted cuttings in commercial grower’s field 2012 in Dalat, Vietnam
  14. 14. Rooted cuttings growing in commercial grower’s field 2012 in Dalat, Vietnam
  15. 15. Farmer multiplying tissue culture plants 2012 in Mountain Trail, the Philippines
  16. 16. Igorota:  generation 3 seed August 2012 in  Mountain Trail, the Philippines
  17. 17. RMT program by farmer: mini tubers sold 2012 in Dalat, Vietnam
  18. 18. Aeroponics Southwest China
  19. 19. National government subsidizes 3G basic seed production China
  20. 20. Results & Impact
  21. 21. Igorota:  yield of 40 T/ha during the rainy season August 2012 in Mountain Trail, the Philippines
  22. 22. Igorota:  growing during the rainy season August 2012 in  Dalat, Vietnam
  23. 23. Igorota, G6, in commercial grower’s field,  bacterial wilt infected plants pulled at first symptoms 2012 in Dalat, Vietnam
  24. 24. C88: processed in large chip factory 2010 in Yunnan, China
  25. 25. C88: sold as a gift to tourists 2009 in Southwest China
  26. 26. Yield Data by Country Location Average  Yield (T/ha) Variety High Yield  Observed  (T/ha) Season Yunnan 16 C88 80 dry Dalat 20 Igorota 40 wet Mountain  Trail 20 Igorota 40 wet
  27. 27. Status of C88 & Igorota in 2012 Variety Area (ha) % of  Total Locations Grown C88 400,000 40 Southwest China, Myanmar, Vietnam Igorota 8,400 70 Dalat, Vietnam  Mountain Trail, the Philippines
  28. 28. RMT Farmer building new home … “The house Igorota built!” 2012 in Mountain Trail, the Philippines
  29. 29. Potato Crop with no visual virus infection, but Late Blight! Ethiopian Highlands
  30. 30. Five Keys to Success 1. Potato Crop is a high value business 2. Varieties with durable resistance to LB &  viruses by local breeding 3. BW management (seed movement from high  to lower elevation & negative selection) 4. Initial seed production is supported by the  public sector 5. Seed production is a profitable business
  31. 31. Opportunity For Landless Youth Demystify Technology!
