The meiotic process in F3BC1 and F4BC1 of crosess S. cereale (2n=28) × Triticale (2n=42) was analyzed. It was established that the variation of number of univalents per cell is heterogenous.The variation of total bivalent number, ring bivalents and rod bivalents per cell characters changes from homogeneous to strongly heterogenous.
The homogeneous variation of the total number of chromosomes shows that the selection of stabilized tetraploids with rye cytoplasm can start first in F3BC1.
