It is shown that the plants of the five investigated species (C. juncea, C. graminea, C. ca-nescens, C. brevirostris, C. latifolia) are characterized by a high degree of defectiveness of pollen (60–80%) and the presence of cytoembryological marker signs gametophytic atomixis. This indicates a high probability of their ability to seed reproduction by apomixis. It is established that the frequency of detection of these signs varies significantly among years and between-population level. It is revealed that C.
