On September 29, 1992, hosted by Yunnan Land Reclamation Bureau, invited experts to conduct preliminary assessment on the topic of “Research on the Introduction, Identification and Utilization of New Brazilian Rubber Germplasm” by the provincial hot work station.

By 1990, a total of 5185 new germplasm of Brazil rubber were introduced from Guangzhou Yantang quarantine nursery and the South China Institute of Tropical Crops.
