摘  要:
采用ISSR分子标记对38份红麻品种进行遗传多样性分析。利用自行筛选的引物共扩增出117条带,其中多态性条带98条,多态性条带比率为83.7%。品种之间的遗传相似系数为0.36~0.98,表明部分红麻品种间存在显著的遗传分化。聚类分析表明:红麻栽培品种间基因型差异较小,亲缘关系较近,遗传基础相对狭窄;而野生种、近缘种和栽培种之间存在着较大的遗传差异性。

摘  要:
Inter-Simple Sequence Repeat(ISSR)molecular markers were used to analyze the genetic relationship of 38accessions of kenaf germplasm.Using 15primers,we amplifed 117bands,of which 98bands were polymorphic and the average percentage of poly-morphic bands was 83.7%.The range of genetic similarity was 0.36-0.98,suggesting that the substantial genetic divergence between some varieties.The cluster analysis suggested that cultivated species had small differences of genetypes and their genetic basis was comparatively narrow,and there were higher genetic diversity within kenaf cultivated species,wild species and relatives.
