摘要: Restriction fragment length polymorphisms (RFLPs) have been used to detect mitochondrial DNA (mtDNA) variation among 9 commercial cultivars of Vicia faba L. The was initially digested with 8 restriction endonucleases revealing complex banding patterns on ethidium bromide (EtBr) stained gels. However, no RFLPs were visualised from these profiles. Southern hybridisation using total mtDNA as a probe against the same enzymes revealed limited number which allowed be consistently distinguished into two main cytoplasmic types. 23 random clones covering 56 kb genome considerable levels polymorphisms. Of analysed, 12 detected at least 22 3 analysed. These analysed in this study 6 separate groups. Most
