Other claims from this paper (8)
- Observation Seven A. ugamicum collections were tetraploid and self-fertilizing.
- Observation One A. ugamicum genome was partly homologous with the S genome of A. spicatum and A. libanoticum.
- Observation A. ugamicum shared only the S genome with four tetraploid Agropyron species.
- Observation The authors designated the second A. ugamicum genome Y and its formula SSYY.
- Observation All hybrids were sterile, precluding introgression.
- Observation The A. libanoticum × A. ugamicum hybrid was exceptionally vigorous.
- Observation The A. ugamicum × A. trachycaulum hybrid was exceptionally vigorous.
- Recommendation The authors proposed that the vigorous hybrids may have forage potential if fertility is restored.
