Chromosome designations follow the nom enclature of Raupp et al. (

1995

) where “T” indicates a terminal translocation, “Ti” indicates an interstitial transloca-

tion, a “•” indicates the location of the centromere, a “-” indicates an interstitial breakpoint, “S” identifi

es the chromosome short arm, “L” identifi

es the chromo-

some long arm, numbers are used to identify the homoeologous group followed by a letter indicating the genomic origin followed

by a superscript identifying

the donor species, and the “#” sign is used to distinguish between homologous chromosomes derived from different donor accessio

ns. In cases where the

genomic origin is unknown only the homoeologous group followed by a superscript indicating the donor species is used; REC = rec

ombinant chromosome,

ROBT = Robertsonian translocation, I = ionizing radiation, HR = homoeologous recombination, S = spontaneous, MU = misd
