Meiosis was observed in pollen mother cells in plants of four rye Secale vavilovii Grossh. lines (nos. 52, 109, 116, 225). The behavior of 2R chromosomes with additional heterochromatin, and of other chromosomes, was observed in diakinesis, metaphase I, anaphase I and anaphase II. 2R chromosomes with additional heterochromatin formed ring and rod bivalents without disturbances. Some other chromosomes formed heterobivalents and trivalents as well as chromosome bridges and chromosome fragments, indicating structural modifications.
