The monitoring of the frequency of apomixis was making in popu- lations of 7 species of Chondrilla in the south of european part of Russia. It is shown that the plants of 6 examined species (C. juncea, C. graminea, C. canescens, C. brevirostris, C. latifolia и C. acantho- lepis) are characterized by their ability to seed reproduction by apo- mixis. This fact is confirmed by results of a study of seed productivity of the species of the genus Chondrilla at the regime of blossoming without pollen and cytoembryological analysis megagametophytes of the same plants.
