摘要: Broussonetia × kazinoki Siebold has long been utilized as a major component in the manufacturing of Korean traditional paper, hanji, and suggested hybrid species B. papyrifera monoica. By applying three molecular markers, chloroplast (cp) ndhF-rpl32 IGS, nuclear ribosomal internal transcribed spacer, TOPO6 gene, origin is tested. As result, Korea demonstrated to be monoica papyrifera, most likely formed naturally Korea. The cp haplotypes detected provided information about origins genetic diversity maternal lineage paternal papyrifera. two markers were supplemented each other, leading discovery introgression Broussonetia.
