Abstract
The results of cytogenetic studies of genome stabilization in secalotriticum are presented. Comparative analysis of microsporogenesis in hexaploid secalotriticum, triticale, and reciprocal hybrids of them (S/RRAABB, T/AABBRR, 2n = 6x = 42) was carried out. The cytogenetic properties and genotypic factors of genome stabilization in heteroplasmic triticale were found. The inheritance by the secalotriticum of the genotypically caused first meiotic division, the so-called reduction division, of univalents from original combinations of rye-triticale hybrids was demonstrated for the first time.
