Cytogenetic peculiarities of cell genesis in apical meristems of apomicts has been analyzed using a series of the Asteraceae species as an example. The extent to which aneu- and mixoploids are spread among plants in the investigated populations of the Asteraceae species is so high (up to 30-60% of the studied plants and their offspring), that it seems reasonable to suppose that their rise is a natural phenomenon. It has been shown that in the aposporous facultative apomict Pilosella officinarum microgametophyte is a relatively stable element of the seed reproduction system from the point of view of caryotypical variation.
