摘要: 选取来自巴西3个州的48份橡胶树(Hevea brasiliensis)野生种质,将胶孢炭疽菌(Colletotrichum gloeosporioides)活化后进行大田接种鉴定及自然条件评价,以筛选抗性种质。橡胶树种质人工接种大田鉴定结果表明,抗病种质3份,中感种质14份,感病种质25份,高感种质6份;自然评价的结果与大田接种鉴定结果显著相关。3份抗性种质均来自于巴西Rondonia州。

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
