| Research Abstract |
Japanese dwarf bamboos(Sasa-group) develop hybrids easily, and the identification on the basis of the external morphologic traits of vegetative organs is difficult. The aim of this study was to investigate the usefulness of chloroplast and nuclear genes as DNA markers for differentiation between Sasa-group hybrid taxa. Thirty-seven and sixteen samples were collected in the University of Tokyo Chichibu Forest and the University of Tokyo Hokkaido Forest, respectively. Intergeneric and interspecific hybrids were identified on the basis of external morphologic traits. At the result of molecular analysis, one of the flowering genes, FLOWERING LOCUS T(FT) may be a useful DNA marker to detect hybrids.
