Primula sieboldii (E. Morren), the ancestor of the Japanese garden Primula, is in danger of extinction in the wild. Genetic diversity is a key component for conservation efforts associated with population management. Genetic diversity in visible traits and several molecular makers were evaluated, respectively. Since it is difficult to determine the degree to which genetic and environmental differences contribute to observed phenotypic variation in natural habitats. A common-garden approach is used. The contribution of genetic and environmental differences to variation in petal shape and area of Primula sieboldii were evaluated. Samples from 108 genets gathered from five natural populations in three regions of Japan were analyzed in a commongarden experiment and also analyzed using eight microsatellite markers. From the results of quantitative evaluation based on image analysis, broad genetic variation in petal traits within populations and low level of population differentiation was found. For all petal shapes, Q_<st> was smaller than F_<st>, suggesting that wild populations might be under moderate selective pressure for a specific phenotype. For petal area, Q_<st>, was nearly equal to F_<st>, suggesting that population differentiation has been caused mainly by genetic drift.
