利用ISSR技术对37份药用石斛属种质资源进行亲缘关系分析,从备选72条引物中筛选出15条引物,共扩增出89条谱带,有89条多态带,多态性条带比例为100%。采用NTSYS‐PC2.0软件分析结果,37份石斛种质资源遗传相似系数在0.50~0.85。聚类结果显示,以相似系数为0.55,可将37份石斛种质明显划分为7个类群,表明药用石斛植物遗传多样性丰富, ISSR技术可应用于药用石斛的亲缘关系研究。
利用ISSR技術對37份藥用石斛屬種質資源進行親緣關繫分析,從備選72條引物中篩選齣15條引物,共擴增齣89條譜帶,有89條多態帶,多態性條帶比例為100%。採用NTSYS‐PC2.0軟件分析結果,37份石斛種質資源遺傳相似繫數在0.50~0.85。聚類結果顯示,以相似繫數為0.55,可將37份石斛種質明顯劃分為7箇類群,錶明藥用石斛植物遺傳多樣性豐富, ISSR技術可應用于藥用石斛的親緣關繫研究。

Genetic relationship of 37 Dendrobium was studied by ISSR technique. Fifteen primers with clear and polymorphic bands were screened out from 72 ISSR random primers. Eighty‐nine locus were detected with polymorphic percentage in 100% . As analyzed by NTSYS‐PC2.0 , the genetic similarity of 37 Dendrobium were ranged from 0.50 -0.85 and grouped into 7 sub‐cluster when the similarity coefficient was 0.55. The results indicated that plants of medicinal Dendrobium were rich in genetic diversity and their genetic relationship could be studied by ISSR technique.
