摘要：

为了全面了解橡胶树野生种质资源对低温胁迫的忍受能力，在2007—2008年发生典型平流型寒害后即采用苗期寒害鉴定和分级方法对1675份1981’IRRDB野生种质资源和215份Wickham栽培种质进行逐株调查。调查结果表明：Wichham栽培种质有19.07%的平均寒害级别小于1级，而野生种质中有55%显示出对低温具有一定的忍耐能力，说明种质群体中存在大量的耐寒基因，且以来自Rodonia地区的抗寒基因材料选出率较高，可作为抗寒种质选择的优质、高效群体。

Abstract:

In order to entirely understand the cold stress adaptability of Hevea brasiliensis, 1675 1981’IRRDB accessions and 215 Wickham clones were investigated in the field germplasm pool after the typical advective cold damage between 2007 and 2008, with the one by one investigation, identification of chilling injury in seeding stage and classification methods. The results showed that there were just 19.07% Wickham clones with the average level of chilling injury below 1 rank, whereas 55% 1981’IRRDB wild Hevea accessions showed a certain degree of cold stress tolerance which indicated that there were quite amount of gene for cold tolerance, especially the accessions which came from Rodonia, it could be a valuable group screening for cold resistance.
