The results showed that the average thousand-seed weight , kernel percentage , kernel oil percentage and seed oil percentage are 567.9 g , 56.671%, 61.781% and 35.133% , respectively. There are very significant differences in thousand-seed weight , kernel percentage , kernel oil percentage and seed oil percentage among populations . The populations marked as Lijiang A, Honghe D, Lijiang B, and
Yuxi A are evaluated as the most potential ones for future development . Temperature is the most significant limitation factors on distribution of J. curcas. There is a remarkable negative correlation between altitude and mean annual temperature of the distribution areas. The dry-hot valleys in Jinshajiang River and Yuanjiang River are the most suitable areas for J. curcas
plantation , and followed by the hot and low elevation areas in Lincang, Baoshan, Puer and Xishuangbanna prefectures. Suggestions were proposed for further studies and development in Yunnan Province .
