This paper reports a new evidence for the multiple origins of the U genome in 2 UM genome tetraploid species, A. binuncialis and A. ovata, based on the PCR-restriction fragment length polymorphism (RFLP) of the U genome-specific U31 fragment developed previously. The PCR-RFLP of the U31 fragment of 48 accessions each of A. binuncialis and A. ovata was investigated. Common alleles were found between the U genome of diploid A. umbellata and A. binuncialis, and between A. umbellata and A. ovata.
