The nature-reserve population of a rare species, Primula sieboldii in the Tajimagahara flood plain of the Arakawa River in Saitama Prefecture has been designated as precious natural product. However, recently the population has decreased tremendously and faces extinction as a result of biological and abiological changes in the environment due to rapid urbanization, etc. In terms of conservation of this rare species, WASHITANI et al. (in press) assessed intrapopulational variations of several characteristics related to fertility and found that there were wide inter-clonal variations of fertility, phenology, etc. and that insect visitation was rarely observed in this area. To build up a scheme for conservation of the population, we tried to clarify the genetic variation within the population.
