Abstract
A mutant designated by the symbol E-1 was selected from the Callistephus chinensis Nees variety 'Dukat' seeds irradiated by a 4335 R dose. The variety 'Dukat' belongs to the group of tall asters with a paeony-type inflorescence of salmon colour. The mutant E-l differed from the outset variety by a stronger anthocyanin colouring of shoots and leaves, short shoots and a compact habit of the plant, smaller leaves, smaller dimensions of inflorescences and two-coloured ligulate flowers - with whitish edges and a violet centre.
