| Research Abstract |
All plants of Lychnis senno existed in Japan are triploid, and are considered to be the same clone. In order to clarify the origin, the chroloplast DNA(PS-ID sequence) of Lychnis senno and those of related taxa was compared. As a result, the DNA of a wild species from Zhejiang province, China was identical with that of Lychnis senno.Thus the Chinese wild species is considered to be conserned in formation of triploid Lychnis senno.Generally triploid plant has low pollen fertility, and has not been utilized for breeding. However, in triploid Lychnis senno, progenies with various characters were obtained by self-pollination, they are considered to be favorable materials for breeding. Although some interspecific hybrids have been obtained by ovule culture, almost all hybrids showed chlorophyll-deficiency.
