We have previously obtained populations of plants harboring mutants of soybean cultivars. In the present study, we analyzed the stability of altered flowering time and chlorophyll content for four to five generations in the field. Differences in the extent of phenotypic changes were detected between generations; the extent of generational variation also differed between plant lines. These results imply the presence of a genetic mechanism that influences the extent of phenotypic changes, which presumably responds to environmental signals.
