Summary

Chromosome variation was studied in bulk populations of 27 advanced strains of hexaploid Triticale. Average frequency of euploids (2n=42) in the 27 strains analyzed was 81.5% with a range from 57.2% to 100.0%. Three strains showed particularly high aneuploid frequency in the bulk population; the average frequency for the three strains was 39.0%, while the mean for the other 24 strains was 14.8%. The progenies of 42-chromosome plants derived from the aforementioned three strains had 89.4% euploids on an average. It is assumed that a monosomic plant was selected in a single-plant (or spike) selection during the breeding period. The frequency of aneuploids is very high, even after several generations of breeding. Routine chromosome checking is recommended in breeding Triticale and other cytologically unstable induced amphiploids.
