为了促进濒危物种三叶报春花的保护和恢复，我们对日本32个剩余野生种群中的8个微卫星位点进行了遗传变异分析。群体内总等位基因多样性在较大的群体中较高，但在疏离调整后则不如此。种群大小与近交系数之间的正相关关系表明，更多的杂合基因在栖息地收缩中幸存下来，可能是由于杂合性相关的适应度较高。通过主坐标分析和贝叶斯分析，我们检测到北海道、本州北部、本州中部和日本西部4个遗传群，这些遗传群可以被认为是p的管理单元。sieboldii。如果计划补充其他种群的植物，则应在属于同一管理单位并可能具有相同适应性变异的种群中进行。
To promote programs for the conservation and restoration of the endangered speciesPrimula sieboldii, we examined genetic variation at eight microsatellite loci among and within 32 remnant wild populations throughout Japan. Total allelic diversity within a population was higher in larger populations, but not so after rarefaction adjustment. The positive relationship between population size and the inbreeding coefficient may suggest that more heterozygous genets tend to survive the habitat contraction possibly because of the higher fitness associated with heterozygosity. By principal coordinate analysis and Bayesian analysis, we detected four genetic groups (Hokkaido, northern Honshu, central Honshu, and western Japan), which could be recognized as management units ofP. sieboldii. If supplementation with plants from other populations were planned, it should be conducted among populations which belong to the same management unit and which are likely to represent the same adaptive variation.
