Other claims from this paper (10)

Observation Nine durum-einkorn amphiploids were obtained.
Observation Most amphiploids had the expected genomic constitution AABBAA.
Observation Three amphiploids retained high resistance to Bgt race E09.
Observation Four amphiploids showed moderate resistance to Bgt race E09.
Observation Two amphiploids were moderately susceptible to Bgt race E09.
Observation Five einkorn accessions carry known Pm genes, including Pm60, Pm60b and PmNCA6/Pm37.
Observation Two einkorn accessions and their amphiploids may harbour novel Pm genes.
Association Amphiploids showed some improvement in tillering, spike length and seed weight in field evaluation.
Association The amphiploids had better seed-setting rates in crosses and backcrosses with common wheat.
Recommendation The amphiploids offer a new bridging platform for transferring alien genes from einkorn to common wheat.
