Mutants obtained from petal tissue in experiment 3 were examined. From light purple and dark purple flower-color mutants, five or ten mutant clones
randomly selected from somaclones or ion-beamed clones were tested, respectively. In the other colors, all the mutant clones were tested
Stability was examined at the individual level as well as at the clone level. The individual level of stability (%) was determined as the number of stable
individuals relative to the total number of individuals tested
Clones that segregated one or more differently colored individuals from the mutated flower color were evaluated as unstable. Thus, clone level stability
is shown as the number of stable clones/number of clones tested
