以湖北省的４０个杉木优树为研究材料，初步开展了运用ＰＣＲ—ＲＡＰＤ技术对杉木优树进行识别的研究。研究表明，运用 ８个引物的 １７个分子标记可以对其中的３８个无性系进行识别，只有２个无性系相互不能识别。说明湖北省杉木遗传资源变异幅度较大，可以运用 ＤＮＡ技术对优树进行品系管理。
In this paper, 40 Cunninghamia lanceolata trees in Hubei Province were used as materials to study the identification of Cunninghamia lanceolata by PCR-RAPD. The results showed that 38 of them could be identified by 17 molecular markers of 8 primers and only 2 of the clones could not recognize each other. This indicated that the genetic variation of Cunninghamia lanceolata in Hubei Province was large and DNA technology could be used to manage the superior tree.
