摘要
用扩增性酶切片段长度多态性(AFLP)分析了来源于世界不同国家地域的23份红麻种质资源和2份红麻近缘种玫瑰茄资源。用选取的6对引物组合获得了505条AFLP分子标记。结果认为AFLP分析是红麻品种鉴定和遗传关系检测的非常有效的手段,同时根据AFLP分子标记检测到的红麻与玫瑰茄之间的遗传差异支持了它们在分类学上的独立性。红麻种质资源的AFLP分析结果支持了红麻起源于非洲的假设,并证实了栽培红麻首先被引到亚洲,并进一步被传播到中北美洲。
To investigate the diversity and genetic relationships, twenty - three kenaf accessions and two accessions of its relative, roselle ( H. sabdariffa var. altissima), were analyzed by AFLP analysis. In this study, a total of 505 polymorphic markers were produced by six selected AFLP primer combinations. It is concluded from this study that AFLP fingerprinting is the more effective tool in identifying of kenaf varieties and determining their genetic relationships. Kenaf and roselle are independent species with close relationships, based on the analysis of the AFLP markers. The AFLP analysis strongly supports the opinion that kenaf originated in Africa. It also demonstrated that the dissemination of kenaf was from Africa through Asia to Central and North America.
