Other claims from this paper (19)
- Observation Chromosomal rearrangements occurred in 70 of 208 tetraploid wheat accessions.
- Observation Chromosomal rearrangements occurred in 69 of 252 hexaploid wheat accessions.
- Observation Chromosomal rearrangements occurred in 3 of 39 triticale forms.
- Observation The study identified 58 types of major chromosomal rearrangements.
- Observation Six chromosome modifications of unknown origin were observed.
- Observation Single translocations were the most frequent aberration type, with 39.
- Observation Nine types of multiple rearrangements were identified.
- Observation Nine types of pericentric inversions were identified.
- Observation Three types of paracentric inversions were identified.

- Observation Breakpoints were in interstitial chromosome regions in 52 cases.
- Observation Interstitial translocation breakpoints were often at C-band borders or between adjacent C-bands.
- Observation B-genome chromosomes were most often involved in translocations, then A- and D-genome chromosomes.
