DNA of 35 species (Table 2). Figure 5 and Figure 6 show the distributions of repetitive 

DNA bands in different genomes and species, respectively. A total of 426 bands were 

observed in the allopolyploid species. Within the diploid species, the A-genome species 

produced 479 band characters, the largest number of band characters, while the K-

genome species produced 96 bands, the fewest number of band characters. The D-

genome species produced 126 band characters and the remaining genome species 

produced character bands between 119 and 181 (Table 3).
