[Hybrids of triticale and agrotriticum. II].
Meiosis in F1 plants of Triticale X Agrotriticum hybrids with 56- and 63-chromosomes and different genome composition is shown to be strongly violated. The following main anomalies of meiosis were revealed: the univalent state of chromosomes; an irregular movement of 8 to 33 chromosomes to the poles; the lag of 6 to 25 chromosomes and their premature splitting into chromatids; formation of micronuclei in diads and tetrads, formation of polyads. The average number of bivalents per one cell was 14.1-14.6.
