Ten mutants and one original cultivar of chrysanthemum (Chrysanthemum × grandiflorum /Ramat./Kitam., syn. Dendranthema grandiflora Tzvelev) representing the Lady Group were analysed for pigment content in the inflorescence by the spectrophotometric method. The respective mutants obtained by ionising radiation differed in their quality and quantity of flavonoids and carotenoids in the inflorescence as compared with the original ‘Richmond’. Each mutant studied exhibited its own permanent repetitive profile of the occurrence of pigments, which allows the possibility of showing the distinctness of the cultivars analysed and may be useful in their identification.
