Abstract: A total of 48 rubber tree（Hevea brasiliensis） clones from three states in Brazil were chosen,which field inoculation and natural conditions evaluation inoculated by purified anthracnose（Colletotrichum gloeosporioides） to evaluate the clone’s resistance level. The result showed that the resistance-susceptibility difference of rubber tree clones was distinct：resistance（3 clones）, mid-susceptibility（14 clones）, susceptibility（25 clones）, and high susceptibility（6 clones）. The results of natural evaluation were significantly related to field inoculation. All the three resistant germplasm came from Rondonia state of Brazil.

Key words: Hevea brasiliensis, wild germplasm, Colletotrichum gloeosporioides, resistance evaluation
