Abstract
The present research investigated the number of chromosomes in the cells of apical meristems of roots for three original Dendranthema grandiflora Tzvelev cultivars and the derivative cultivars obtained due to radiomutation. It was shown that only in one mutation cultivar, ‘Bronze Wonder’, the number of chromosomes differed from that of the original cultivar, ‘Lilac Wonder’. Key words: Dendranthema grandiflora, mutants, chromosomes.
