Asian Seed Potato Production SystemsRelated to the Highlands of Africa

Locations: Yunnan, ChinaDalat, Vietnam Mountain Trail, the Philippines

Elevation: 1500 to 3,000 m aslLatitude: 11 to 24 NConstraints: late blight, 

bacterial wilt (lower elevations), viruses

Five Keys to Success1. Potato Crop is a high value business2. Varieties with durable resistance to LB & 

viruses by local breeding3. BW management (seed movement from high 

to lower elevation & negative selection)4. Initial seed production is supported by the 

public sector5. Seed production is a profitable business
